2026 Research Report | Cheapest Auto Insurance
How much can car insurance prices vary when the driver, vehicle, and coverage remain the same? In Oklahoma City, the difference can exceed $5,000 over a six-month policy.
An analysis of September 2026 insurance data found that premiums for a 16-year-old male driver ranged from $1,158 to $6,845 across participating insurance companies. Both figures were based on the same standardized driver scenario, producing a $5,687 difference between the lowest and highest six-month premiums.
The gap extended beyond younger drivers. Among 10 standardized Oklahoma City driver profiles, eight showed a highest-to-lowest insurance price ratio of at least five to one.
To investigate these differences, Cheapest Auto Insurance analyzed 200 premium observations published by the Oklahoma Insurance Department alongside 348 original online quote scenarios covering drivers ages 18 through 75.
The research examines how insurance prices vary between companies, how those differences change across driver profiles, and what additional quote data reveals about age and discount configurations in Oklahoma City.
Key Findings From the 2026 Oklahoma City Car Insurance Study
The research identified five notable findings:
- Eight of 10 driver profiles had at least a fivefold difference between the highest and lowest insurer premiums. Significant price differences appeared across younger, middle-aged, and older driver scenarios.
- The largest six-month price gap was $5,687. The highest premium for a standardized 16-year-old male profile was nearly six times the lowest.
- A 36-year-old male profile had a $2,095 price gap. The median premium was $1,064, compared with the lowest published rate of $391.
- Insurance quotes did not change at every age. In our original no-discount analysis, 47 of 57 consecutive age transitions showed identical displayed monthly prices.
- The four-discount configuration produced an average quoted monthly installment approximately 24% lower than the no-discount configuration. The difference between the published monthly averages was $17.69.
These findings use two separate datasets with different vehicles and coverage assumptions. The insurer comparisons and original quote scenarios are analyzed independently rather than combined into one average Oklahoma City insurance rate.
The Largest Oklahoma City Insurance Price Gap Reached $5,687
The Oklahoma Insurance Department’s September 2026 rate comparison provides a way to examine how different insurers price standardized driver profiles.
The department asked participating companies to provide six-month premiums for a 2018 Chevrolet Malibu LS with Oklahoma’s 25/50/25 liability limits and $500 comprehensive and collision deductibles.
Our analysis examined 20 insurer entries across five age groups, with separate male and female scenarios, totaling 200 premium observations.
Oklahoma City Car Insurance Price Differences by Age
The following figures show the lowest, median, and highest six-month premiums across the 20 insurer entries for each male-driver profile.
| Driver age | Lowest premium | Median premium | Highest premium | Price gap |
| 16 | $1,158 | $4,179 | $6,845 | $5,687 |
| 21 | $649 | $1,758.50 | $3,431 | $2,782 |
| 36 | $391 | $1,064 | $2,486 | $2,095 |
| 55 | $371 | $881 | $2,349 | $1,978 |
| 70 | $392 | $824.50 | $1,979 | $1,587 |
Source: Oklahoma Insurance Department, September 2026. Medians and price gaps calculated by Cheapest Auto Insurance. Figures represent six-month sample premiums, not average premiums paid by Oklahoma City residents.
The largest difference appeared in the 16-year-old driver scenario, where the most expensive insurer’s premium was $5,687 higher than the least expensive.
Yet substantial differences remained across older profiles.
For the 55-year-old male scenario, premiums ranged from $371 to $2,349. That’s nearly $2,000 in variation for the same vehicle and coverage specifications.
The 70-year-old profile also showed a $1,587 difference between the highest and lowest published premiums.
These findings demonstrate that large insurer price differences were present throughout the age groups examined, rather than being limited to teenage drivers.
The age scenarios also have different marital-status, annual-mileage, and vehicle-use assumptions. Therefore, the figures compare insurer prices within each profile and should not be interpreted as measuring the independent effect of age.
Eight of 10 Driver Profiles Showed a Fivefold Price Difference
Looking at the complete state dataset reveals a broader pattern.
Across the five male and five female driver scenarios, eight had a highest premium at least five times the lowest.
All five male-driver profiles met that threshold.
For the 36-year-old male profile, the most expensive premium was approximately 6.4 times the least expensive. The 55-year-old male profile showed a similar ratio of approximately 6.3 to one.
The price gap was therefore substantial even for profiles with no reported accidents or moving violations in the previous three years.
This matters because insurance companies use different rating systems and underwriting requirements when determining premiums.
Although insurers received the same scenario specifications, they did not produce similar prices.
The results do not establish which insurer will be cheapest for every Oklahoma City resident. Each company’s published rate assumes the applicant meets its underwriting criteria, and individual discounts may change the actual premium.
The Median Premium Tells Another Story
Looking only at the highest and lowest premiums can make a price gap appear to be driven by an unusually expensive quote.
The median helps provide additional context.
For the 36-year-old male profile, the median six-month premium across the 20 insurer entries was $1,064. The lowest was $391.
That is a $673 difference between the lowest premium and the midpoint of the published rate distribution.
A similar pattern appeared in the 55-year-old male profile, where the median was $881 compared with a low of $371.
The $510 difference shows that the price variation was not limited to the highest-priced entry in that sample.
However, these medians describe the 20 published insurer entries, not the median amount paid by Oklahoma City residents. Multiple entries also belong to related insurance groups, meaning the analysis does not represent 20 independently owned insurance brands.
Does the Cheapest Insurance Company Change by Driver Profile?
Another finding was that the lowest-priced insurer was not identical across every age group.
In the state comparison, State Farm Mutual Automobile Insurance Company reported the lowest premium for the 16-year-old male scenario at $1,158.
GEICO Secure Insurance Company reported the lowest premiums for the male profiles at ages 21, 36, 55, and 70.
This indicates that an insurer’s relative pricing position can change depending on the characteristics of the driver scenario.
It also helps explain why company rankings based on a single driver profile have limited value for someone with different circumstances.
A company that offers competitive pricing for one age group may use different rating or underwriting rules for another. Individual eligibility, previous insurance, driving history, and other factors still matter when obtaining a personalized quote.
What Our 348 Oklahoma City Quotes Reveal About Driver Age
To examine pricing differences in greater detail, Cheapest Auto Insurance also analyzed 348 online insurance quote scenarios collected through its affiliated insurance quoting operations in September 2026.
The dataset included every age from 18 through 75, male and female driver profiles, and three discount configurations.
The sample used a 2014 Toyota Camry with Oklahoma’s minimum liability limits of 25/50/25 and a six-month policy term.
Unlike the Oklahoma Insurance Department comparison, these quotes were for minimum liability coverage without collision or comprehensive protection.
How Monthly Liability Quotes Changed Across Age Groups
| Driver age | No discounts | Four discounts |
| 18 | $148.33 | $112.25 |
| 21 | $94.00 | $68.25 |
| 25 | $73.50 | $54.08 |
| 30 | $69.67 | $51.25 |
| 35 | $68.83 | $50.42 |
| 45 | $66.00 | $51.58 |
| 55 | $64.67 | $50.25 |
| 65 | $64.67 | $51.00 |
| 70 | $66.67 | $54.42 |
| 75 | $74.75 | $54.42 |
Source: Cheapest Auto Insurance analysis of September 2026 company quote data. Figures are monthly installment amounts averaged across the male and female profiles for each age.
The most noticeable difference appeared between younger and middle-aged driver profiles.
At age 18, the no-discount monthly quote was $148.33. By age 25, it had decreased to $73.50, representing a difference of $74.83, or approximately 50%.
The decline became considerably smaller across later age groups.
For the age-30 profile, the no-discount quote was $69.67. At age 55, it was $64.67, a difference of only $5 per month.
However, the analysis revealed something more interesting than the difference between younger and older drivers.
Insurance Quotes Did Not Decrease at Every Birthday
Across all 58 ages in the no-discount sample, only 11 distinct monthly prices appeared.
Of the 57 consecutive age transitions, 47 showed no change in the displayed quote.
The longest period of unchanged pricing occurred between ages 50 and 66, when the no-discount monthly figure remained at $64.67.
The biggest year-to-year decrease appeared between the age-20 and age-21 profiles, with the monthly price falling from $121.75 to $94.00.
That’s a difference of $27.75.
By comparison, the difference between ages 24 and 25 was $17.17.
These findings challenge the assumption that a driver’s insurance price necessarily becomes lower at every birthday or that turning 25 always produces the largest reduction.
In the tested scenarios, monthly quote averages followed a stepwise pattern, with several consecutive ages sharing the same displayed price. The results do not establish how individual insurers structure their age-based rating rules.
The study also does not predict how the premium for one individual will change as they get older. Each figure represents a separate standardized quote scenario rather than a long-term record of one driver’s policy renewals.
How Much Difference Did Insurance Discounts Make?
The original quote analysis also examined whether different discount configurations produced different monthly installment prices.
Three scenarios were tested:
- No discounts applied
- Automatic payments only
- Automatic payments, homeowner, prior insurance, and defensive driver discounts combined
Across the 58 ages, the results showed the following average monthly installments.
| Discount configuration | Average monthly quote |
| No discounts | $72.77 |
| AutoPay only | $70.00 |
| Four discounts combined | $55.08 |
Source: Cheapest Auto Insurance analysis of September 2026 company quote data.
The four-discount configuration produced an average quoted monthly installment approximately 24% lower than the no-discount configuration in the tested sample.
That represents a $17.69 difference between the published monthly averages.
The dollar difference was not identical across all ages.
At age 18, the no-discount quote was $148.33, compared with $112.25 under the four-discount configuration. That was a $36.08 monthly difference.
At age 55, the corresponding difference was $14.42.
The results show that discount configurations were associated with different quoted prices, and the dollar differences varied by age.
These figures do not guarantee that every driver can receive the same discounts or achieve the same savings.
The no-discount and four-discount scenarios were collected on September 3, 2026, while the AutoPay-only scenarios were collected on September 6. Because of this timing difference, the AutoPay comparison should not be treated as a controlled measurement of its individual effect.
Why Are Insurance Prices So Different in Oklahoma City?
The findings demonstrate substantial variation, but the study does not establish which individual pricing factor caused each insurer’s premium.
According to the Oklahoma Insurance Department’s guidance on choosing automobile insurance, insurance companies may consider driving history, vehicle characteristics, garaging territory, age, accidents, and other rating factors when determining premiums.
Each company also has its own underwriting guidelines and pricing models.
An insurer may place a different level of emphasis on certain characteristics or operate different insurance programs for different types of applicants.
That helps explain why standardized insurance scenarios can result in different prices.
Does the Oklahoma City ZIP Code Matter?
An important consideration for local drivers is where a vehicle is normally kept.
Insurance companies may use garaging territory when calculating premiums, meaning an address change within the Oklahoma City area can affect a personalized quote.
However, the research presented here does not establish how premiums differ between individual Oklahoma City neighborhoods.
The company’s original quote research used a single Oklahoma City location input. A separate controlled experiment using verified residential garaging addresses would be necessary to determine how much otherwise identical insurance quotes change across the city’s neighborhoods.
The study therefore focuses on differences between insurance companies, driver profiles, and discount configurations rather than neighborhood-level insurance rankings.
What the Research Means for Oklahoma City Drivers
The findings illustrate why a single advertised insurance price cannot represent the range of premiums available to every applicant.
In the state comparison, insurers quoted substantially different premiums for the same standardized driver scenario. Meanwhile, the original quote data showed that age-related prices did not change every year and that different discount configurations were associated with different monthly costs.
For someone comparing insurance, these results support three practical considerations.
Compare equivalent coverage. A lower monthly price may reflect different liability limits, deductibles, or coverage selections. Minimum liability insurance also differs significantly from a policy that includes comprehensive and collision.
Review quotes based on your actual circumstances. Driver age, previous coverage, vehicle details, garaging address, and eligibility requirements can influence which insurance options are available.
Consider the total policy cost. Monthly installments, first payments, payment-plan fees, and discounts can affect the amount ultimately paid for a policy.
For Oklahoma City residents, understanding these details can make insurance comparisons more meaningful than choosing a company solely because it advertises a low starting price.
Research Methodology and Data Sources
This report combines two separate data analyses conducted by Cheapest Auto Insurance.
Study 1: Oklahoma Insurance Department Rate Comparison
Source: Oklahoma Insurance Department, September 2026 Auto Insurance Rate Comparison
Research specifications:
- Geographic market: Oklahoma City
- Published insurer entries: 20
- Driver scenarios: Five ages, with male and female profiles
- Total premium observations analyzed: 200
- Sample vehicle: 2018 Chevrolet Malibu LS four-door sedan
- Coverage: 25/50/25 liability, with $500 comprehensive and collision deductibles
- Policy term: Six months
- Driving history: No accidents or moving violations within the preceding three years
The state-defined scenarios use different assumptions for age, marital status, annual mileage, and vehicle use.
Cheapest Auto Insurance calculated each profile’s minimum, median, maximum, dollar difference, and highest-to-lowest premium ratio using the department’s published figures.
The median represents the midpoint of the 20 insurer entries after premiums are ordered from lowest to highest. For an even number of entries, the two middle values are averaged.
The price gap is calculated by subtracting the lowest premium from the highest premium within each profile. The highest-to-lowest ratio is calculated by dividing the highest published premium by the lowest.
The state comparison excludes individual operator discounts but includes applicable vehicle-related discounts. Rates also assume that each hypothetical applicant qualifies under the insurer’s underwriting guidelines.
Study 2: Original Oklahoma City Insurance Quote Analysis
Source: Cheapest Auto Insurance company-affiliated quote research, September 2026.
Research specifications:
- Collection period: September 3–6, 2026
- Geographic reference: Oklahoma City
- Quote scenarios: 348
- Driver ages: 18 through 75
- Profile categories: Male and female
- Discount configurations: Three
- Sample vehicle: 2014 Toyota Camry
- Coverage: Minimum liability, 25/50/25
- Policy term: Six months
The 348 scenarios represent 58 ages multiplied by two driver-profile categories and three discount configurations.
The report analyzes the published monthly installment figures, averaging the male and female quotes within each age and discount scenario.
The analysis includes calculations of age-to-age differences, unchanged pricing periods, and differences between the discount configurations.
These figures represent standardized quote scenarios rather than completed customer purchases or a representative survey of Oklahoma City residents.
What the Data Does Not Tell Us
Several limitations are important when interpreting the results.
The figures are not average premiums paid by Oklahoma City residents. The state data uses hypothetical driver profiles, while the original quote dataset contains standardized insurance quote scenarios rather than a representative sample of customers.
The two datasets cannot be combined into one insurance price average. Their vehicles, coverage selections, and collection methods differ.
The study does not establish the cheapest company for every driver. Actual policy eligibility and pricing depend on each applicant’s circumstances.
The research does not isolate every pricing factor. The government profiles differ in more than age, and differences between quote configurations should not automatically be interpreted as causal savings.
The research does not rank Oklahoma City neighborhoods. The original quote scenarios used one geographic input, and a controlled comparison across multiple residential garaging locations was not performed.
The original quote records have not been independently audited for every underwriting assumption. The findings describe the collected scenarios and the published monthly figures rather than verified outcomes across the entire local insurance market.
All figures reflect the conditions and collection periods described above. Insurance pricing may change after publication.
Data Availability and Calculation Notes
The government premium observations used in this research are publicly available through the Oklahoma Insurance Department’s September 2026 rate comparison.
The article presents the calculated insurer price gaps, medians, and selected monthly quote results. The original online quote findings are based on company-affiliated pricing records and their published age-by-age summaries.
For transparency, the figures in this report should be interpreted using their original units: six-month premiums for the government comparison and monthly installment amounts for the company quote analysis.
The two types of prices are not interchangeable and are not combined to produce a single average.
Conclusion: Oklahoma City’s Insurance Price Gap Is Larger Than One Rate Comparison Suggests
The central finding of this research is that substantial insurance price differences exist across standardized Oklahoma City driver scenarios.
Among the 10 profiles examined in the Oklahoma Insurance Department’s September 2026 comparison, eight showed at least a fivefold difference between the highest and lowest six-month premiums.
The largest gap reached $5,687, while the 36-year-old male profile showed a $2,095 difference between insurers.
Our additional analysis of 348 original quote scenarios revealed another pattern: age-related monthly prices remained unchanged across most consecutive age transitions in the tested no-discount configuration, while different discount configurations produced noticeably different quotes.
These findings demonstrate why insurance prices are best evaluated using consistent coverage specifications and individual driver information rather than relying on one advertised rate.
