About this calculator

Keeping a car for a decade changes the story: more tyre sets, batteries and uncertain late-life repairs, but depreciation flattens.

Use this when you buy to keep rather than flip after the loan ends.

Formula summary

OwnershipEngine estimate with years fixed at 10.

Assumptions

  • Insurance, service and repair reserves use your inputs or site default percentages.
  • Resale residual is an assumption, not a live market bid.
  • All totals are indicative estimates — not guarantees of future costs.
  • Long horizons amplify uncertainty in fuel prices and repairs.

FAQs

Are major repairs included?

A percentage repair reserve is included; sudden engine or dual-clutch jobs can exceed it. Raise the reserve if the car is complex or high-km.

How is 10-year resale set?

Defaults lean toward a lower residual. Override only with grounded market knowledge.
