Investment Calculator

Use our Investment Calculator to see what a starting investment and a regular contribution could grow to, the contribution you need to reach a target balance, or how long it will take to get there.

Choose whether you add money monthly, quarterly or yearly, and whether it goes in at the start or the end of each period. Your return is compounded at the same frequency, and the annual fee is taken off the return — the calculator shows what that fee costs you over time.

Because prices rise, the results also show what your balance is worth in today’s dollars, and how the answer changes if your return is a little lower or higher than you expect.

Returns, fees and inflation are kept steady, and taxes are not included, so treat the results as an estimate. To plan for retirement, use our Retirement Calculator with Inflation or, for two people, our Couple Retirement Calculator. To see how much compounding itself adds, compared with simple interest, use our Simple vs Compound Interest Calculator. If interest compounds on a different schedule from your deposits — daily, say, with deposits every two weeks — or you want to see how long regular withdrawals last, use our Compound Interest Calculator with Contributions.
