Accumulating a balance and funding a life are separate calculations.

A retirement calculator can show how contributions and an assumed return build a balance. It cannot, by itself, establish a sustainable income or a retirement date.

Accumulation is the first phase

The accumulation question is arithmetic: how does current savings plus recurring contributions change under an assumed rate and time period? The answer is sensitive to contribution timing, fees, inflation and the return assumption.

Income introduces new risks

Withdrawals change the direction of the balance. Spending needs may rise with inflation, returns may arrive in an unfavourable order, and taxes differ by account and jurisdiction. Longevity also turns a single balance into a time-and-uncertainty problem.

Use scenarios, not one finish line

Test lower returns, different contribution levels and delayed starts. Treat the outputs as comparisons that expose trade-offs. They are not a promise that a portfolio will earn the entered rate.
