Store description excerpt
Before you sign up for a bank product, instantly see "how much will I actually get at maturity" and "how much do I need to repay each month" with a fully offline interest calculator. No account, no network, no permissions required. 💰 Deposit Calculator Enter the principal, annual rate, and term, choose simple or compound interest, and instantly get pre-tax interest, tax withheld, and the after-tax payout. The tax rate defaults to 15.4% (Korea standard) but can be edited directly to match tax-free or reduced-tax products. 📈 Savings (Installment) Calculator Enter the monthly deposit, annual rate, and term to see the maturity payout along with pre-tax and after-tax interest. 🏦 Loan Repayment Calculator Enter the loan amount, annual rate, and term, choose a repayment method (equal principal & interest / equal principal / lump-sum), and get the monthly payment and total interest. 📊 Principal vs. Interest Visualization See the ratio between principal and interest at a glance with a simple bar chart on the results screen. 🌏 Korean / English support Pick your preferred language right in Settings. 🔒 Privacy-friendly No sign-up or login needed. Amounts and rates you enter are stored only on your device and never sent to any server. Deposits, savings, loans — let Simple Interest Calculator handle the math.
