Frequently asked questions

How is the monthly payment calculated?

It uses the standard amortization formula: each payment covers the interest for the month and the rest reduces the balance, so the interest part shrinks over time.

Does paying extra help?

Yes. Extra payments go straight to the balance, which shortens the loan and cuts the total interest. Try the amortization schedule calculator to see by how much.
