Reading the result

Returns, charges, inflation and contributions remain constant. Negative annual returns can be entered to explore losses.

How it works

An assumed effective annual return is reduced by an annual percentage charge. The equivalent monthly factor grows the balance before each month-end contribution; inflation discounts the final value.

Worked examples

Worked example

Initial investment (£): 10000; Monthly investment (£): 200; Assumed annual return (%): 5; Years: 20; Annual charge (%): 0.5; Annual inflation (%): 2

Can investments lose money here?
