## What is Compound Interest?

AssetCurve is a simple, private calculator for rough compound-growth estimates.

Three ways to use it:
- Future Value: enter a starting amount, monthly contribution, expected annual return, and years to see an estimated future balance.
- Withdrawal: enter your assets and a monthly withdrawal to see roughly how long the money could last.
- Goal Backsolve: work back from a target to the monthly contribution, the number of years, or the annual return it would take.

Every result comes with a balance chart and a year-by-year table showing contributions and estimated growth.

Private by design:
- Everything is calculated on your device
- No account, no ads, no tracking, no network connection

AssetCurve is not investment advice and does not recommend any investment. Results are rough simulations with monthly compounding and do not guarantee future outcomes. Taxes, fees, inflation, currency changes, and market volatility are not included.
