Store description excerpt

Compound interest is the eighth wonder of the world. Compound makes you feel it. Type in a starting amount, what you deposit (daily, weekly, monthly, quarterly or yearly) and an interest rate. Compound instantly plots your wealth curve on a beautiful interactive chart. Hold the chart and scrub through the years to watch your money grow. THE MOMENT THAT CHANGES EVERYTHING Compound finds your crossover year: the year your interest starts earning more than everything you put in. From that point on, your money works harder than you do. BUILT FOR CLARITY - Interactive growth chart with invested vs. interest, with haptic scrubbing - Full breakdown table, per year or per month - Effective rate (APY), time to double, and what your money earns per day - Inflation mode: see every amount in today's purchasing power - Growing deposits: model a yearly raise on your contributions - Compounding per day, week, month, quarter or year WHAT IF... ...you had put your exact plan into Bitcoin, gold, the S&P 500 or a savings account, starting 5 or 10 years ago? A dose of perspective, based on approximate historical returns. For perspective only; past performance says nothing about the future. SCENARIOS Save any plan, compare them head to head on one chart, and swipe to clean up. Your pension plan vs. your house fund vs. your FIRE dream. STAY ON TRACK Optional monthly wealth check on the 1st of every month: open the app and see what compounding did while you slept. 21 CURRENCIES Dollar, euro, pound, yen and more. PRIVATE BY DESIGN No account. No tracking. Everything stays on your device. Compound does not provide financial advice. Projections are mathematical illustrations based on the numbers you enter.
