See how much time and money you save by paying a little extra each month — uses your current loan above.
Compare two loan offers to see which actually costs less over the full term.
Your monthly payment uses the standard amortization formula, factoring in your loan principal, annual interest rate (APR), and loan term in months. Each payment covers accrued interest first, then reduces the outstanding balance.
Rates depend on the loan type, your credit score, and market conditions. Borrowers with excellent credit (740+) typically qualify for significantly lower rates. Even a 0.5% difference on a 30-year mortgage can save tens of thousands.
Even small extra payments toward principal can dramatically shorten your loan term and reduce total interest paid. Use the Extra Payment Calculator above to see exactly how much you'd save.
