Compound Growth, Contributions & Solver Toolkit
Calculate future value, total interest, required return, and full growth schedules with flexible compounding and deposit timing.
Future Value
—
Total Interest Earned
—
Effective Annual Yield
—
Estimated End Date
—
Results assume a constant rate and no taxes, fees, or withdrawals. If your rate changes over time, run multiple scenarios.
Future Value
—
Total Contributions
—
Total Interest Earned
—
End Date
—
Contribution mode models steady deposits and constant rate growth. For irregular deposits, use the schedule tab as a planning proxy.
Required Annual Rate
—
Effective Annual Yield
—
Approx. Periodic Rate
—
Required rate is solved numerically and is sensitive to contribution timing and compounding frequency. Use conservative assumptions for planning.
Required Contribution
—
Contribution Per Year
—
Estimated Total Contributed
—
Required contribution is solved numerically and assumes steady deposits and constant rate. If returns vary, consider running conservative and optimistic cases.

Schedules illustrate the mechanics of compounding. Real-world investing can differ due to fees, taxes, variable rates, and irregular contribution timing.
