Model extra monthly principal on a mortgage and compare payoff timelines with a balance-over-time chart for base vs accelerated payments.
How to use this tool
1. Enter loan principal, APR, and original term in years. 2. Add your planned extra monthly payment. 3. Click Calculate. 4. Review savings and the balance chart comparing base vs extra-payment paths.
Worked example
Example: $250,000 mortgage at 6.5% for 30 years with an extra $200/month saves several years and tens of thousands in interest versus the standard payment schedule.
How it works
Enter your mortgage balance, interest rate, original term, and an extra monthly payment. The calculator compares standard vs accelerated payoff, showing months and interest saved plus a balance-over-time chart for both scenarios.
