Frequently Asked Questions
What does “More money down will save you” mean here?
It is the present value of paying a larger down payment today in exchange for a lower car payment each month, using your entered investment return (after tax) as the discount rate. It is lower than raw interest savings because tying up cash has an opportunity cost.
Why can this differ from another website?
Rounding, last-payment treatment, and how opportunity cost is modeled vary. Use results for directional planning, not as a lender quote.
