Quick Answer: How do extra payments affect a mortgage?
Specifically, because standard mortgages use an amortization schedule that heavily front-loads interest, applying even a small extra payment directly to your principal balance bypasses future interest charges. For example, paying an extra $100 per month on a 30-year loan can shave several years off the term and save tens of thousands of dollars in lifetime interest.

How accurate are these debt payoff estimators?
Our estimators use standard financial amortization formulas to project interest savings and payoff timelines. Actual results may vary slightly based on your specific lender’s daily or monthly compounding schedule. We recommend reviewing guidelines from the Consumer Financial Protection Bureau (CFPB) for official lending standards.
Is my loan and financial data stored?
No. All interest, debt, and asset calculations run entirely via local Javascript in your browser. We never store, collect, or transmit your personal financial data to any server.
These tools provide mathematical estimates only and do not constitute certified financial, mortgage, or legal advice.
