About

Loan & Deposit Calculator helps you quickly calculate loan payments, deposit returns, interest, and amortization schedules. It supports four calculation modes:

• Simple Interest — flat-rate interest on a fixed principal • Compound Interest — interest accrued on principal plus accumulated interest • Annuity Loan — equal monthly payments (standard mortgage / consumer loan) • Straight-line Loan — fixed principal payments with decreasing interest

The app works fully offline and stores nothing on external servers.

Frequently Asked Questions

How is annuity payment calculated? PMT = P × r / (1 − (1 + r)^−n), where P is principal, r is monthly rate, and n is number of months.

How is compound interest calculated? A = P × (1 + r/n)^(n×t), where P is principal, r is annual rate, n is compounding periods per year, t is time in years.

Do you store my calculation data? No. All calculations happen on your device. Nothing is sent over the network, logged, or shared.

Can I export the amortization schedule? Yes — use the share button on the Schedule view to send results via Mail, Messages, or copy to clipboard.

Why does the app show "Interest" under the icon but a different name in the App Store? "Interest" is the short label for the Home Screen; "Loan & Deposit Calculator" is the full App Store name.
