Car Maintenance Cost Calculator
Project realistic maintenance and repair costs as your car ages and the miles add up — annual average and 5-year total.
How much will car maintenance cost?
It rises with age and mileage. This tool starts from a per-mile rate for a new car and grows it about 8% for each year of age. On the defaults — a 5-year-old car driven 12,000 miles at $0.05 a mile — that's about $840 this year and roughly $4,680 over the next five years, near $936 a year on average.

Insight — Maintenance cost climbs as a car ages — tires, brakes, fluids and out-of-warranty repairs stack up. Once annual upkeep approaches a car payment, it's often the signal to compare repair vs replace.
What if Vehicle age changes?
| Vehicle age | Estimated annual maintenance |
|---|---|
| 1 yr | $648 |

Typical range: public estimates put car maintenance and repair around $0.09–$0.10 per mile averaged over a car's life (published driving-cost data). This tool starts lower for a new car (about $0.05/mile) and grows it ~8% per year of age to approximate that curve. Use your own figures for a closer estimate.
How this calculator works
This is a modeled estimate, not a quote. The calculator multiplies your annual miles by a per-mile maintenance rate, then raises that rate by about 8% for every year of vehicle age to reflect wear items and out-of-warranty repairs stacking up. It reports this year's cost, a five-year projection that ages the car one year at a time, and the implied cost per mile.
Formula
Annual cost = annual miles × per-mile rate × (1 + 0.08 × age). Five-year total sums that cost for the car's current age through four years older.
Worked example
A 5-year-old car driven 12,000 miles at $0.05 a mile: 12,000 × $0.05 × (1 + 0.08 × 5) = $600 × 1.40 = $840 this year. Summing ages 5 through 9 — $840, $888, $936, $984, $1,032 — gives about $4,680 over five years, roughly $936 a year and $0.07 a mile.

Good to know
Clear, practical answers about the maintenance cost calculator.
How much should I budget for car maintenance per year?＋
A common rule is $0.05–0.10 per mile, so 12,000 miles a year is roughly $600–$1,200. Older and luxury vehicles run higher, while newer mainstream cars under warranty run lower.
Why does maintenance get more expensive as a car ages?＋
Wear items (tires, brakes, suspension, belts) reach replacement intervals, the factory warranty expires, and the odds of a larger repair rise each year. This tool grows the per-mile cost by about 8% for every year of age.
When does it make sense to replace instead of repair?＋
A useful benchmark: if a single repair — or a year of repairs — costs more than a few months of payments on a replacement, or exceeds the car's value, replacing usually wins. Compare against your annual figure above.
