Vehicle Replacement Calculator

Vehicle reliability doesn't decline evenly — as components approach end of life, breakdown frequency tends to accelerate rather than increase at a flat rate. Projecting a 20% downtime increase reflects that aging vehicles typically become progressively less reliable year over year, not just marginally more expensive to maintain.

New vehicles typically benefit from updated engine technology, less mechanical wear, and often stricter fuel efficiency standards than the vehicle they're replacing, especially when the current vehicle is several years old. This assumption lets the comparison account for one real advantage of replacement that a pure maintenance-cost comparison would otherwise miss.

A vehicle sitting in the shop isn't generating revenue even when the repair bill itself is modest, and that lost productivity is a real cost that maintenance spending alone doesn't capture. Multiplying expected downtime days by their daily cost puts that lost-revenue impact on equal footing with the maintenance, fuel, and depreciation costs that are easier to see on an invoice.

It estimates how many years of annual savings from replacing now it would take to recover the difference between the new vehicle's price and the current vehicle's remaining value. A short break-even period suggests replacement pays for itself quickly, while a long one suggests keeping the current vehicle remains the more cost-effective choice for now.
