About this app

Amortize is a fast, clean set of eight loan calculators — the mobile companion to Amortization-Calc.com. Enter your numbers on a purpose-built keypad and get a complete picture of any loan: monthly payment, total interest, payoff date and a full month-by-month amortization schedule with yearly subtotals.

CALCULATORS

• Mortgage — PITI breakdown with property taxes, insurance, HOA and PMI (including the date PMI drops off), LTV, extra-payment savings
• Refinance — new payment after refinancing, with optional cash out
• Auto Loan — trade-in, sales tax and down payment in dollars or percent
• Personal Loan — terms in years, months or weeks
• Business Loan — origination and documentation fees financed into the loan
• Reverse Mortgage (HECM) — principal limit, line of credit, lump sum, monthly tenure payment and an equity projection chart
• Mortgage Payoff — see how extra monthly or one-time payments shorten the loan and how much interest they save
• Car Loan Payoff — the same acceleration math for your car loan

EVERYTHING ON ONE SCREEN

Swipe the results panel in from the right: headline figures, a summary table, an interactive chart of principal, interest and balance by year, and the full payment schedule. Tap any year on the chart for its exact numbers.
