Compound Savings Calculator

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.
