Calculate monthly payments and amortization in Simple mode, run refinance breakeven checks, and compare multiple loan scenarios side by side.
In Simple mode we use the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n – 1], where P is principal, r is monthly rate, and n is total months. This gives a fixed payment for fully amortizing loans.
An amortization schedule shows every payment over your loan's term, breaking down how much goes to principal vs. interest each month. Early payments are mostly interest; later payments are mostly principal.
Refinancing can help when rate or term improvements outweigh closing costs. Use Refinance mode to compare your current loan against a new offer and review breakeven timing before deciding.
Extra payments go directly to principal, reducing your interest costs and shortening your loan term. Even small additional payments can save thousands over the life of a loan. Use our calculator to see the impact.
