Separate market return from fund cost

The gross return and expense ratio are applied as separate annual factors. The fee impact includes both the cost and the compound growth that money could have earned.

How the calculation works

The calculator applies the values in chronological order and keeps deposits, withdrawals and calculated growth separate. This makes the result easier to audit.

Formula used

annual net factor = (1 + gross return) × (1 − TER)

Assumptions and limits

Rates stay constant for the whole scenario. Taxes, product rules and market volatility are excluded unless the tool explicitly includes them.

How to use the result

Treat the output as a comparison of assumptions. Change one input at a time and compare the final balance, cash flows and growth.

How the calculation works

Is the sensitivity range a forecast?

No. It shows the same cash flows at a lower and higher constant return so you can see how strongly the assumption affects the result.

Is this a forecast?

No. It is an educational calculation based on the values you enter.

Can I compare scenarios?

Yes. Change one assumption at a time and compare the final balance and yearly table.

Are taxes included?

No, unless the page explicitly says otherwise.
