❓ Frequently Asked Questions
What is the power of compounding?
Compounding allows you to earn interest on your interest, leading to exponential growth of your investment over time.
How often should interest be compounded?
The more frequent the compounding (e.g., monthly vs annually), the higher the final amount will be.
Which compounding frequency should I choose?
More frequent compounding (monthly/daily) yields slightly higher returns than annual—choose what matches your account terms.
Do you include contributions?
Use principal plus the compounding frequency to model growth. A future update may add recurring contributions explicitly.
How accurate are results?
We use the standard compound interest formula and preserve decimals for precision.
Is this investment advice?
