How this calculation works
Value = M × ((1 + r)^n − 1) ÷ r × (1 + r), using annual rate ÷ 12 as r. At 0%, value = M × n.
Assumptions & limitations
Illustrative monthly compounding with deposits at the beginning of each month. Actual bank RDs may use quarterly compounding and different day-count rules. Before tax.
