Methodology & how to use this
Formulas used
We use the future-value-of-an-annuity formula: FV = PMT × ((1+r)^n − 1)/r with monthly compounding at your APY. When solving for months we simulate month-by-month until the balance reaches the target.
Practical caveat
Real high-yield savings APYs move with the Fed. Re-check the rate quarterly — a 1% APY change compounds meaningfully over years.
