Vehicle EconomicsVehicle Upgrade Break-Even Price
What is the most a candidate upgrade should cost, given how much cheaper it is to run than what you drive now?
Why this comes up
Current Car vs Candidate Vehicle answers "does this specific candidate at this specific price beat what I drive now." This engine flips the question: given how much cheaper the candidate is to run, what is the most it should cost before switching stops making sense? Useful when you have not settled on a real price yet, and want a ceiling to shop against.
How we calculated this
We compute your current vehicle's remaining-life cost over your chosen horizon, then search for the candidate price at which its total cost, financing, depreciation, fuel, insurance, maintenance, repairs, and transaction costs, exactly equals that figure. Any price below that ceiling makes the candidate cheaper overall; any price above it does not.
Worked example, using this page's own defaults over 5 years: run the calculator above to see the exact price ceiling for a candidate with lower fuel, insurance, and maintenance costs than a $12,000 current vehicle running $1,500/year in depreciation.
What this means
- A candidate with meaningfully lower running costs can justify a real price premium over your current vehicle, not just price parity.
- This is a modeled ceiling from your own assumptions, not a market prediction or a recommendation to spend up to it.
- Once you have a real candidate price, Current Car vs Candidate Vehicle gives you the direct forward comparison.
Limitations
Depreciation, fuel, and every operating cost figure for both vehicles are your own flat annual estimates. If no price in a wide plausible range produces a solution, the search reports that directly rather than guessing. See Methodology.
Methodology
This engine reuses Current Car vs Candidate Vehicle's own ownership total cost and amortization functions inside a break-even search, so the two engines never drift apart. See Methodology for the full detail.
