How to use this calculator
- 1
Enter loan amount, interest rate, and term
Loan amount is the original principal (or current balance if modeling mid-loan). Rate is annual interest rate. Term is total loan duration in years (15, 20, or 30 typical for investment).
- 2
Review the monthly payment
The monthly P&I (principal + interest) payment is fixed for the life of a standard amortized loan. The calculator shows this before you look at the schedule.
- 3
Scan the schedule
Each row is a month. Notice that in month 1 most of your payment is interest, and by the final months almost all of it is principal.
- 4
Model extra principal payments
An extra $100-$200/month applied to principal can cut years off a 30-year loan and save tens of thousands in lifetime interest. Use the extra-payment field to see the impact.
