Compound Savings Calculator

About this app

Compound interest is the closest thing to free money — but it only works if you can actually see it. CompoundCalc turns your principal, rate, and time into a clear projection so you know exactly how much your money will be worth. Most calculators spit out one lonely number. CompoundCalc draws the whole curve: a year-by-year growth chart, a running principal-vs-interest split, and a side-by-side of compound against plain simple interest — so you can watch returns start earning returns. WHAT YOU GET - A projected final balance from your principal, annual rate, and time horizon - A growth chart that shows exactly when compounding starts to snowball - Compound frequency you control: daily, monthly, quarterly, semi-annual, or annual - Recurring deposits modeled on a monthly, quarterly, or yearly schedule - A clean principal-vs-interest breakdown of every dollar you end up with - Saved scenarios you can compare to find the plan that grows fastest PERFECT FOR - Savers deciding how much to set aside each month - Investors sizing up long-term returns before committing - Anyone planning a retirement nest egg or emergency fund - Students learning how compounding and the Rule of 72 really work WHY NOT JUST USE A SPREADSHEET? Because a spreadsheet won't chart the snowball, split principal from interest, or let you flip between saved plans in a tap. CompoundCalc does the math the moment you move a slider — no formulas to fix, no cells to break. PRIVACY Every projection stays on your device. No accounts, no ads, no tracking — ever. FULL ACCESS CompoundCalc is free to project a balance and view the growth chart. Premium unlocks recurring deposits, unlimited saved scenarios and comparisons, and the full year-by-year breakdown table. Upgrade with a weekly or yearly subscription, or a one-time lifetime purchase. Subscriptions auto-renew until cancelled; manage or cancel anytime in your App Store account settings. Set a deposit, pick a rate, and see your money compound — start your first projection today.
