Check a zero-interest example

A principal of 1200 over 12 months at 0% annual interest gives a monthly payment of 100, a total of 1200 and no interest.

When to use it

For an interest-bearing loan, the estimate assumes equal payments and a constant rate. Compare it against the lender’s complete cost disclosure.
