How this calculator works
Use the explanation to understand the formula, assumptions, and practical limits behind the calculator result.
What This Calculator Does
This calculator projects future net worth from current savings, income, savings rate, expected return, and years invested. It applies compound growth to the current balance and recurring contributions.
What Drives the Projection
The biggest levers are time, contribution size, and return assumption. Starting earlier gives contributions more years to compound, while even a modest change in return can create a large gap over decades. The result is a scenario, not a promise: taxes, inflation, fees, income changes, withdrawals, and market volatility can all move the real outcome.
Use the calculator to compare conservative, base, and optimistic cases. If you need a retirement-specific plan, compare the result with the retirement and savings-goal calculators rather than treating one projection as a complete financial plan.
Frequently asked questions
Why does starting earlier matter so much?
Because compounding needs time. Earlier contributions have more years to earn returns on both the original money and the returns already earned.
Should I use nominal or real returns?
Use nominal returns for future dollars and real returns when you want purchasing-power comparisons. Mixing the two can make a projection look more precise than it is.
What is missing from this projection?
Taxes, investment fees, inflation changes, irregular contributions, withdrawals, and market volatility may all be omitted or simplified depending on the scenario you enter.
How should I compare the scenarios?
Compare several scenarios instead of trusting one forecast. A conservative case is usually more useful for planning than a single optimistic number.
