Project investment growth

How to use the investment growth calculator

1. Enter the initial amount and the monthly contribution.
2. Enter the expected annual return and the product's annual fee.
3. Enter the term and review the projected value and its yearly growth.

Investment growth formula

Net return = return − fee · Value = C × (1 + i)^m + A × ((1 + i)^m − 1) / i

What each variable means

C

initial amount

A

monthly contribution

i

monthly net return

m

months

Fees look small but compound: half a point a year can cost thousands over the long term.

Investment growth example

With €5,000 to start, €200 a month, a 6% return and a 0.5% fee (5.5% net) over 20 years, you contribute €53,000 and the projection reaches €102,108.61.

Illustrative example with the data shown; not a guaranteed outcome.

Assumptions and limitations

• Constant return; in reality it varies every year and can be negative.
• The fee is deducted from the return each year.
• Taxes and inflation are not included.
