A loan payoff planner for iPhone, iPad, and Mac: calculate payments, model extra payments, and compare scenarios side by side — fully offline.
What does Amortize calculate?
Enter your loan amount, interest rate, term, and start date, then tap Calculate. Amortize shows your monthly payment, total interest, payoff date, a principal-vs-interest breakdown, and a year-by-year payoff ladder.
How do extra payments work?
Use the Extra Payment slider to add a fixed amount on top of your monthly payment. The payoff ladder updates instantly — the gold bars show your balance with extra payments, and faint blue bars behind them show where you'd be without them, so you can see exactly how many years and dollars you're saving.
What are scenarios?
Every calculation is automatically saved as "Loan 1", "Loan 2", and so on, forming a timestamped history with the newest on top. Tap any scenario to load it back into the calculator, or give it your own name with the Save button. Select two scenarios to compare them side by side.
How do I delete a saved scenario?
Swipe left on a scenario in the list and tap Delete.
What do the timestamps under scenario names mean?
They show the date and time each scenario was calculated or saved, down to the second.
Does Amortize need an internet connection?
No. Everything is computed on your device and the app works fully offline.
What data does Amortize collect?
None. No account, no analytics, no ads. See our Privacy Policy.
