Example setup: initial value 100,000, annual contribution 12,000, projection 10 years, inflation 2.50%, contributions at year end.

Formula Used

Weighted gross return = Σ (normalized asset weight × expected return).

Weighted fee drag = Σ (normalized asset weight × annual fee).

Weighted tax drag = Σ (normalized asset weight × max(expected return − fee, 0) × tax rate).

Net nominal return = weighted gross return − weighted fee drag − weighted tax drag.

Real return = ((1 + net nominal return) ÷ (1 + inflation rate)) − 1.

Future value = initial portfolio growth + future value of yearly contributions, adjusted for contribution timing.

FAQs

1) What does this calculator measure?

It estimates portfolio return from your asset mix, then subtracts fees and tax drag. It also projects future value and inflation-adjusted value over your selected time horizon.

2) Must my weights total exactly 100%?

No. The calculator automatically normalizes weights when the total differs from 100%. It still shows your entered total so you can catch input mistakes quickly.

3) Why are fees and taxes separated?

Separating them shows how much return disappears from costs versus taxes. This makes it easier to compare fund choices, account types, and tax-efficient allocation strategies.

4) What is real return?

Real return adjusts nominal performance for inflation. It reflects purchasing power growth instead of headline growth, which is often more useful for retirement and long-term planning.

5) How are taxes handled here?

The tool applies tax drag only to positive post-fee gains for each asset. It is a planning estimate, not a replacement for account-specific tax advice.

6) Can I use negative returns?

Yes. You can enter negative expected returns for stress testing. That helps model bear markets, conservative forecasts, or downside scenarios across specific asset classes.

7) What does contribution timing change?

Beginning-of-year contributions compound for longer than end-of-year contributions. Choosing the right timing gives a more realistic estimate of future portfolio value.

8) When should I export results?

Export when you want to document planning assumptions, compare scenarios, or share a portfolio estimate with a client, partner, or adviser.
