FAQ
What is an annuity payment?
A payment schedule where the total monthly payment stays the same throughout the loan, though the split between principal and interest shifts over time — the most common structure for consumer loans and mortgages.
Does this include fees or insurance?
No, this is a pure interest calculation based on principal, rate, and term — add any fees or required insurance separately for a complete cost picture.
What if the interest rate is 0%?
The calculator correctly handles a 0% rate by simply dividing the principal evenly across the term with no interest added.
