Savings and Investment Calculator
Model how starting capital, ongoing contributions or withdrawals, time, and an annual growth rate combine. Use a custom CAGR or a historical Grizzly Bulls/SPX preset, then inspect the projection rather than relying on one ending number.
Enter data in all but one field below, then calculate the missing value.

Use the chart as a scenario, not a forecast
The starting-capital line shows what you began with. Net capital adds your cumulative contributions or withdrawals. The modeled total applies the CAGR assumption, and the gap between total value and net capital shows the compounded effect.
Try different rates and contribution schedules to see which assumption drives the result. Historical presets are useful reference points, not expected future returns.
