How this is calculated
This uses the compound interest formula with monthly contributions. Each month, we calculate interest on the current balance, add it, and then add your monthly contribution.
Formula: A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)]
Example: $1,000 at 12% for 1 month: $10 interest. Balance becomes $1,010. If you add $100, final is $1,110.
