FAQ
What is compound interest?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. This differs from simple interest, which is calculated only on the principal.
How are regular contributions calculated?
Contributions are added at the frequency you select and earn interest for the remaining duration. The calculation assumes contributions are made at the end of each period.
What's the difference between APR and APY?
APR (Annual Percentage Rate) does not account for compounding, while APY (Annual Percentage Yield) includes the effect of compound interest over a year.
Are these results guaranteed?
No. This calculator provides illustrative estimates based on the inputs you provide. Actual returns may vary based on market conditions and other factors.
Why is this version different?
It's the same math, just presented without overwhelming options. Enter numbers, see estimates. That's it.
Do I need to understand compounding?
Not in detail. The key concept is that money may grow faster the longer it has to compound. The calculator shows an illustrative projection.
