Did You Know?
How Does Money Market Growth Work?
Compound Interest
Your initial deposit grows via FV = P(1 + r/n)^(nt) with monthly compounding (n=12).
Regular Deposits
Monthly deposits add PMT × [((1 + r/n)^(nt) - 1) / (r/n)] to future value.
Tax & Inflation
Interest is taxed as ordinary income. Real value = after-tax balance ÷ (1 + inflation)^t.
