How this calculator works
The standard amortization formula produces the base payment. Extra payments are applied to principal, which shortens the term and reduces interest.
Frequently asked questions
Is this only for personal loans?
It works for any fixed-rate installment loan: personal, student (simplified), or furniture financing.
What if my rate is variable?
Use a conservative average rate. Variable loans can change.
Why include extra payments?
Even small extras can cut months and hundreds in interest.
