Repair vs. Replace Calculator

Based on the numbers you provide, the calculator gives you the total cost per mile of each option. For the repair option, it factors in the cost of the repair spread over the expected remaining lifetime (in miles) of the vehicle. For the replacement option, it factors in the purchase price and other associated costs. The option that gives you a lower cost per mile is likely the better choice financially.

It's the ongoing cost to keep the vehicle running, averaged per mile. It includes scheduled maintenance and typical repairs that occur over the lifetime of ownership. The calculator's default value is based on data reported by AAA. For vehicles more than 5 years old, you should increase the number by a small amount, as these costs tend to increase as vehicles age.

This factor can swing the result all by itself. For a modern vehicle, 200,000 total miles is a reasonable target. But you should consider the vehicle's overall condition and the likelihood of additional repairs.

If you stay at or under the break-even cost, then the repair gives you an equal or lower cost per mile vs. replacing the vehicle. If the repair puts you over the break-even cost, then replacing the vehicle becomes a more appealing option.

Definitely. If you choose to replace your current vehicle, the sale price or trade-in value offsets the purchase price of the replacement vehicle. You should enter a realistic number that accounts for the vehicle being sold "as-is" with repairs needed.

The calculator is mathematically correct. The more accurate your inputs are, the better the analysis will be. Take your time and enter accurate information for the best results.
