- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of payments (term in years × 12)

Monthly Payment: $477.50
Total Interest: $3,650
Total Payment: $28,650

- Refinance when rates drop: Even a 0.25% rate drop can save thousands.
Common Mistakes to Avoid
- Not including taxes and fees: Real loans include additional costs.
- Ignoring extra payment options: Even small extras make a big difference.
- Choosing too long a term: Longer terms mean more interest paid.

Adding $100/month to a $250,000 mortgage at 4.125% saves $36,000 in interest and pays it off 4 years early.
15-year: higher payments, less interest. 30-year: lower payments, more interest. Use the calculator to compare.
