Engine Type Comparison

Estimate ownership cost over 1 to 10 years — depreciation, fuel, insurance, maintenance, repairs, financing and taxes. Useful when choosing between two cars or comparing new vs used.

Engine Type Comparator

Compare ICE, hybrid, PHEV, battery-EV and hydrogen on annual energy and maintenance.

How It Works

Aggregates depreciation curves (steepest first 3 years), historical maintenance schedules by make/model, average insurance by class, and current fuel prices.

Formula: Total cost = depreciation + fuel + insurance + maintenance + repairs + financing + taxes − resale value.

How to Use This Calculator

  1. Enter purchase price, ownership years and annual miles.
  2. Set fuel economy and fuel price.
  3. Add insurance and financing.
  4. Calculator returns total cost broken down by year and category.

Worked Example

Example: $30k Toyota Camry, 5 years, 15k mi/yr, $3.50/gal, 32 mpg, $1 200 insurance. 5-yr TCO ≈ $33k (depreciation $13k, fuel $8k, insurance $6k, maint $3k, taxes $3k).

Reference Table

Cumulative depreciation reaches 55–60% by year 5 on average.

Year Major cost driver
Year 1 Depreciation 18–22%, no major maintenance
Year 2 Depreciation 12–15%, first major service ~$300
Year 3 Depreciation 10–12%, tire replacement $600–1 200
Year 4 Depreciation 8–10%, brake service $400–800
Year 5 Depreciation 7–9%, timing belt or major scheduled service
Year 6+ Depreciation flattens to 5–7%, repair costs rise

Frequently Asked Questions

How is this different from 5-Year TCO?

The TCO tool gives a single 5-year total. This tool shows the year-by-year curve so you can see when costs spike and plan for them.

What’s the cheapest year of ownership?

Usually years 3–4 — depreciation has slowed, the original warranty is still active or recently expired, and major repairs haven’t started yet.
