What Is a Payoff Date Calculator?
Your mortgage's scheduled payoff date is fixed by the term, but extra payments move it earlier. This calculator simulates the loan month by month with your extra payment amount to find the actual payoff date and the interest saved.
It works from your current balance and rate, so it is accurate for loans that are partway through their term.
How It Works
The standard amortization is simulated with the extra amount applied each month. Every extra dollar reduces the balance immediately and the interest charged thereafter — that is where the savings come from.

Frequently Asked Questions
When will my mortgage be paid off?
Enter your balance, rate and payment — the calculator simulates every month until the balance reaches zero.
How much interest can extra payments save?
Each extra dollar skips future interest on itself. The calculator totals the saving over the remaining term.
What is the difference between payoff date and amortization end date?
The scheduled end date assumes no extra payments; extra payments shorten it.
Should I round up my payment?
Even $50 extra per month can cut years off a 30-year loan — the calculator shows the exact effect.
Does it account for the rate changing?
No — it assumes your current fixed rate continues to payoff.
