The True Cost of Owning a Mazda MX-5 Miata

Cost example updated October 25, 2026

Start with the price you will actually pay

For a representative example, use a 2025 Mazda MX-5 Miata Sport soft-top with the six-speed manual at $30,515. That is the 2025 Sport starting price including the $1,185 destination charge, as reported from Mazda's announced pricing. Two listings put the same car lower before destination: $29,330 before destination, and a dealer table lists $29,530. Kelley Blue Book lists the Sport at $30,715 and Edmunds lists it at $30,765, so the example price sits inside the published spread, and the differences come from whether destination is included and when each listing was updated. The Sport is manual-only and soft-top-only; the Club soft-top starts around $34,015 including destination and the Grand Touring around $35,815, so replace this starting point with a written quote for the exact trim you are considering.

The down payment does not make the Miata cheaper; it changes how much you finance (borrow). With 10% down ($3,052), 8% APR (the yearly interest rate on the loan) and 60 months, and the 7% sales tax ($2,136) and $900 in title and dealer fees rolled into the loan, this example finances $30,500 at $618 a month, and the loan costs about $6,606 in interest over five years. The 7% sales tax is a national-style assumption for this model page, not any one state's rate, your state's tax changes the amount financed.

Fuel: small car, premium gas, honest math

The 2.0-liter four-cylinder with the six-speed manual is rated 29 mpg combined (26 city, 34 highway). At 12,000 miles a year that is about 414 gallons annually, roughly $2,152 a year, $10,759 over five years at $5.20 a gallon. That $5.20 is the AAA national average for premium gas on October 24, 2026, and premium is what Mazda recommends for the full 181-horsepower rating; regular is allowed with a small power loss. If you run regular instead, the same miles at the October 24, 2026 regular average of $4.30 a gallon would cost about $8,897 over five years, roughly $1,862 less, so the fuel line here is the premium case, stated openly. One more honest note: iSeeCars finds Miatas are typically driven only about 5,373 miles a year in their first ten years, well under this page's 12,000-mile example, so a weekend-only Miata would burn less fuel than this example shows. The method behind that math is in the EV vs. gas guide: miles divided by mpg, times price, times years.

Depreciation is the biggest bucket, but a smaller one than most sports cars

Depreciation is the value a vehicle loses over time. iSeeCars puts the MX-5 Miata's five-year value loss at about 36.3%, it keeps roughly 63.7% of its price. On a $30,515 purchase, that means a resale value near $19,438 after five years, about $11,077 of depreciation, roughly $185 a month.

Three conflicts, stated rather than settled: a comparison citing iSeeCars for the 2026 model puts the loss at 33.5% ($10,223 depreciation, $20,292 resale); a report on the 2021 model citing iSeeCars puts the loss at 30.8%; and CarEdge's figure for a 2021 model implies only about a 20.7% loss (79.3% kept). Those older-model figures describe cars bought years ago in a different used market, not a forecast for a 2025 car, which is why this page uses the current 36.3% figure and why the resale number here is a planning assumption, not a promise: run a second scenario with resale 10% lower so the decision does not depend on an optimistic used market.

Insurance runs sports-car money, with a wide spread

Full-coverage averages for an MX-5 Miata spread widely depending on the source: MoneyGeek averages about $137 a month overall and $152 for a 2025 model, Compare.com averages $179, InsuredBetter averages about $145, and Insurify averages $214. This example uses $152 a month, or $9,120 over five years, the 2025-specific figure, inside the published range, not at either end. Premiums depend heavily on the driver, ZIP code, coverage and insurer, and a second-car, low-mileage Miata can price very differently from a daily driver, so get a quote on the exact trim with matching deductibles (what you pay first on a claim) and limits before treating any average as yours.

Miata maintenance costs: small car, small bills

RepairPal puts MX-5 Miata repair and maintenance costs near $429 a year on average, with a 4.0-out-of-5.0 reliability rating, and owners averaging only about 0.3 unscheduled shop visits a year. This example allows $600 a year, or $3,000 all-in for maintenance and repairs, above the RepairPal average to leave room for routine upkeep and a set of tires inside five years. A Miata's tires are small and comparatively cheap next to a truck's, which is part of why the allowance stays modest. The cushion still matters after the warranty years: the basic warranty runs 3 years or 36,000 miles while the powertrain runs 5 years or 60,000 miles, so years four and five are when out-of-warranty items would first land on the owner.

The full five-year example

Every figure below comes from the site's own calculator math. The stated inputs are: 2025 Mazda MX-5 Miata Sport soft-top with a six-speed manual, $30,515 price, 10% down ($3,052), 8% APR, 60 months, 7% sales tax (national-style assumption, not a state rate), $900 in title and dealer fees, 12,000 miles per year, 29 mpg, $5.20 per gallon premium (AAA, October 24, 2026), $152 per month insurance, $600 per year maintenance, $19,438 resale value after five years. The sales tax and fees are rolled into the loan, so the amount financed is $30,500.

• Depreciation: $11,077 ($30,515 minus $19,438 resale)
• Insurance: $9,120 ($152 x 60 months)
• Fuel: $10,759 (12,000 / 29 x $5.20 x 5 years)
• Maintenance: $3,000 ($600 x 5 years)
• Tax, fees and interest: $9,642 ($2,136 sales tax, $900 fees, $6,606 loan interest)

That totals roughly $43,598, or about $727 a month. Notice what that says about the $618 payment: on this roadster the payment is about 85% of the average month's true cost, and during the loan years the cash actually going out is the payment plus insurance, fuel and upkeep.

Formula

The five-year total is the sum of five buckets: depreciation, insurance, fuel, maintenance, and tax, fees and interest. Depreciation is the $30,515 price minus the $19,438 resale value after five years, which is $11,077. Insurance is $152 a month times 60 months, which is $9,120. Fuel is 12,000 miles a year divided by 29 miles per gallon, times $5.20 a gallon for premium, times 5 years, which is about $10,759. Maintenance is $600 a year times 5 years, which is $3,000. Tax, fees and interest is 7% sales tax on $30,515, which is $2,136, plus $900 in title and dealer fees, plus about $6,606 of loan interest, which is $9,642.

Added together, $11,077 plus $9,120 plus $10,759 plus $3,000 plus $9,642 equals $43,598, or about $727 a month. The amount financed is $30,500, as stated on this page. At 8% APR over 60 months, the payment on $30,500 is $618 a month, and the loan costs about $6,606 in interest over five years.

Why Miata buyers should think past year five

Miatas are keepers, iSeeCars puts the average lifespan near 149,000 miles, about 24.6 years, and that is where the economics can improve: the loan ends at year five, and the depreciation curve flattens. The costs that arrive later are the wear-and-repair years: tires, soft-top upkeep, and the out-of-warranty items no average can predict for one specific car. The keep it 10 years guide shows how to extend this same math honestly.

Calculation transparency

Jurisdiction. United States. Sales tax, titling, registration and insurance rules are set by your state, so your exact numbers depend on where you buy and register the car. The 7% sales tax and $900 in fees in this example are planning figures, not any one state's actual rates.

Rules and time period. Five years, 12,000 miles a year, premium gas at $5.20 a gallon (AAA national average for premium, October 24, 2026), 8% APR, 60 months, 10% down. The resale value is a planning assumption, not a forecast.

Scope and limitations. Educational estimate only. Insurance and maintenance are planning figures, not quotes. Get a real quote for the same trim, coverage and loan before you decide.

Sources disagree on the Miata's five-year value loss: iSeeCars puts it at 36.3 percent, while other iSeeCars-based figures put the loss at 33.5 percent for a 2026 model and 30.8 percent for a 2021 model, and CarEdge's figure for a 2021 model implies only about a 20.7 percent loss, so the 36.3 percent figure used here is kept as a planning assumption, not as a current reading. The $30,515 example price also sits below Kelley Blue Book's current $30,715 and Edmunds' $30,765 listings, and it is kept as printed. RepairPal puts average annual repair costs at $429, below the $600 a year used here, and that figure is kept as printed.
