Portfolio Calculator

Amount invested today The lump sum already invested. Use 0 if you are starting from nothing.

Expected annual return (%)Your own nominal return assumption before fund costs. Nothing here forecasts a market.

Compounding periods a year (1/year)1 for an annually compounded return, 12 for monthly, 365 for daily.

Years invested (years)

Annual fund cost (expense ratio) (%)Deducted from the return before compounding, as a fund deducts its expense ratio.

Compounding periods

Worked out from Lump-sum compound growth, FV = P(1 + r/n)^(nt), with growth = FV - P and 2 other sources.

The return is the assumption you entered, not a forecast. Investment returns are not fixed and a portfolio can lose money.

How this is worked out

4 steps

Net return = 7% gross - 0% fund cost = 7% a year, compounded 1 times a year.
Growth factor per period = 1 + 7/(100 * 1) = 1.07.
Lump sum alone: 10000 * (1 + r/n)^(n*t) over 20 years.
Ending balance = 38696.84; of that, 28696.84 is investment growth on 10000 paid in.
