Questions & answers
Is nominal interest the same as APR?
Not necessarily. APR may include lender fees and other charges under local rules. This model uses only the nominal interest rate and does not calculate regulatory APR.
Which repayment method has the smallest payment?
At a positive rate, equal-principal payments start higher and decline; equal monthly payments stay steady. Interest-only starts with just interest but leaves all principal due at maturity. Compare total interest and the final payment too.
