What this calculator helps you understand
A goal planner works backward from a target amount and time horizon to estimate a monthly contribution. It can help compare how the required contribution changes when expected returns, inflation or the time horizon change.

Open calculator ↗How to use the result
Change one assumption at a time and compare the outcome. Use conservative, base and optimistic assumptions rather than relying on a single forecast.
Important assumptions and limitations
The target is adjusted using the inflation assumption, and monthly contributions are assumed at month-end. Returns are not guaranteed; review the assumptions and consider a range of outcomes.
Frequently asked questions
Are the results guaranteed?
No. Results are estimates based on the values entered and simplified assumptions. They are not forecasts or guarantees.
Are taxes and fees included?
No. Unless a calculator explicitly asks for a fee or tax input, those costs are excluded. Rules vary by country and product.
