Do the arithmetic before you commit

Three questions to answer with numbers instead of instinct. What a plan compounds into, what a fund's ongoing charge takes back, and what it takes to reach a figure you have in mind. Everything runs in your browser and nothing you type is stored.

Every calculator publishes the assumptions it runs on. A constant annual return is a planning device, not a forecast. Real markets do not deliver the same number every year, and the order the good and bad years arrive in changes what you end up with.
