Frequently Asked Questions
What is compound interest?
Compound interest means your balance earns returns on both the original principal and previously earned interest, so growth accelerates over time.
Why are contribution frequency and compounding frequency separate?
In real savings plans, you might contribute monthly while interest compounds quarterly or annually. Keeping them separate produces a more realistic projection than forcing both to use the same cadence.
What happens when the rate is 0%?
At 0%, the future value is simply your initial deposit plus all recurring contributions. The calculator still works and shows zero interest earned.
Does this include taxes, fees, or inflation?
No. This is a nominal pre-tax projection. Investment fees, taxes, and inflation can materially reduce your real return.
