Frequently asked

Questions about the lump sum annual return calculator

What return do I need to reach my goal?

The calculator solves for it: the steady annual rate that grows your lump sum into the target over your timeline. It is the hurdle your investments must clear.

What if the required return is unrealistic?

If it exceeds what you can safely earn, extend the timeline, add regular contributions, or lower the target. Chasing an unrealistic return usually means taking imprudent risk.

Is a higher required return riskier?

Yes — higher returns generally require holding riskier assets with bigger swings. Make sure the return you need matches a risk level you can actually tolerate.
