How to use these calculators
Each calculator focuses on a core decision point that shapes long-term results: saving rate, costs, risk tolerance, and inflation. Keep inputs realistic and consistent. When comparing scenarios, change only one variable at a time so you can isolate its effect. Annual return inputs are net of taxes and before platform fees unless stated otherwise. Markets do not move in straight lines, so results are ranges rather than promises. Use outputs to inform a written plan that you can follow through different conditions. Revisit your assumptions periodically, especially after major life events, to ensure your plan still aligns with your horizon and capacity for risk. If you find a concept unclear, move to the learning paths in our guides and then return to the tools with fresh context.
Contribution Planner
Estimate a future portfolio value using monthly contributions. Assumes monthly compounding at a constant annual rate. This is an educational model and not a forecast.
Enter values and select Calculate to see the projection.
Fee Impact Comparator
Compare outcomes with your annual fee versus a low-cost benchmark of 0.10%. Uses a constant gross return to highlight fee drag. Taxes and trading costs are excluded.
Enter values and select Calculate to compare fee scenarios.
Drawdown Simulator
Understand the impact of a peak-to-trough decline and the return required to recover. This helps with setting rebalancing rules and planning cash buffers.
Enter values and select Calculate to see the effect of a decline.
Inflation Adjuster
Estimate how much money you may need in the future to match today’s purchasing power. Useful for planning emergency funds and long-horizon goals.
Enter values and select Calculate to see the inflation-adjusted amount.
