Tips for Best Results
- Always use the actual interest rate from your loan documents. Do not guess. Your loan’s APR (Annual Percentage Rate) includes fees and gives you the true cost of borrowing.
- Make extra payments as early as possible. Interest accrues on your remaining balance. Extra payments made early in the loan term save the most money.
- Round up your monthly payment. Paying $1,000 instead of $987.42 might seem small, but over time it adds up to significant interest savings.
- Consider bi-weekly payments. Making half your monthly payment every two weeks results in 26 half-payments (13 full payments) per year — one extra payment annually that shortens your loan term.
- Check for prepayment penalties. Some loans charge fees for paying off early. Always verify with your lender before making extra payments.
- Use the amortization schedule to understand your loan. Look at how much interest you pay in the first year compared to the last year — it will motivate you to pay extra early.
Common Mistakes to Avoid
- Only looking at the monthly payment. A longer loan term lowers your monthly payment but dramatically increases total interest. Always compare total interest paid across different terms.
- Ignoring loan fees and closing costs. Origination fees, application fees, and prepaid interest affect your true borrowing cost. Add these to your loan amount for accurate calculations.
- Forgetting about variable interest rates. If your loan has a variable rate, your payments can increase. Use the calculator with a higher rate to stress-test your budget.
- Not accounting for escrow accounts. For mortgages, your monthly payment may include property taxes and insurance. Our calculator can include these if you enable the advanced options.
- Assuming all extra payments apply to principal. Some lenders apply extra payments to future interest. Specify in writing that extra payments should go toward principal.
- Taking on more debt than you can afford. A general rule: your total monthly debt payments (including housing) should not exceed 36-43% of your gross monthly income.
