Formula and method
This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:
- Total lease cost:
leaseMonthly*leaseMonths - Net buy cost:
buyMonthly*buyMonths - residualValue
Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.
Examples
- Example: with Lease monthly payment = 350, Lease term = 36 months, Loan monthly payment = 450, Loan term = 60 months, Estimated resale value after loan term = 12000, this calculator returns Total lease cost = 12600, Net buy cost = 15000.
