How it works
The starting balance grows by the monthly interest rate each month. Monthly contributions are added to the compounding balance, so older deposits earn interest longer.
Worked example
Starting with $10,000, adding $200 monthly for ten years at 6% annual interest produces about $52,000, depending on contribution timing.
Keep in mind
This is a fixed-rate projection; real investments can rise or fall and may have fees or taxes.
