Frequently Asked Questions

How much can extra payments save me?

Even small extra payments save significant amounts. On a $300,000 30-year mortgage at 7%, an extra $200/month saves approximately $80,000 in interest and cuts 7 years off the loan. The earlier in the loan you start, the more you save.

Where do extra payments go?

Extra payments go directly to your principal balance. This reduces the balance that future interest is calculated on, creating a compounding benefit — every dollar of extra principal reduces all future interest charged against it.

Should I make one extra payment per year instead?

Yes, one extra full payment per year (making 13 payments instead of 12) is equivalent to roughly $250/month extra on a $300K loan. It takes about 5 years off a 30-year mortgage. Both strategies are effective — use whichever fits your budget.

What is a bi-weekly payment schedule?

Instead of 12 monthly payments per year, bi-weekly payments mean 26 half-payments — equivalent to 13 full payments. This one extra payment per year can shave 4-6 years off a 30-year mortgage and save tens of thousands in interest.

Does my lender apply extra payments immediately?

Most lenders apply extra principal payments when received if clearly marked as principal-only. Always specify "apply to principal" on extra payments. Some lenders hold extra payments until the next due date — check your loan servicer policy.

What is my break-even point for making extra payments?

Unlike refinancing, extra payments have no break-even point — they save money from day one. Every extra dollar reduces your balance and the interest calculated on it. The only consideration is whether the money could earn more invested elsewhere.

Can I make a lump-sum extra payment?

Yes. A one-time lump sum applied to principal can dramatically reduce your loan term. For example, $10,000 extra on a $300K 30-year loan at 7% early in the loan saves roughly $25,000 in interest and 18 months off the term.

What is the payoff date shown in the calculator?

The payoff date is the month and year your loan will be fully paid off given the payment amounts you enter. Making extra payments moves this date earlier. The calculator shows both your current payoff date and your accelerated payoff date side by side.
