  1. Rate per period

    i = annual rate ÷ 100 ÷ 12

    7 ÷ 100 ÷ 12 = 0.005833333333

  2. Months until retirement

    m = (retirement age − current age) × 12

    (65 − 35) × 12 = 360

  3. Balance: savings and contributions grown

    S × (1 + i) to the power of m + C × ((1 + i) to the power of m − 1) ÷ i

    50,000.00 × (1 + 0.005833333333) to the power of 360 + 500.00 × ((1 + 0.005833333333) to the power of 360 − 1) ÷ 0.005833333333 = 1,015,810.37

Estimates for general information only — not financial advice.

How it works

Balance = S(1 + i)^m + C((1 + i)^m − 1) ÷ i with i = annual return ÷ 12 and m = 12 × years to retirement; today's dollars = balance ÷ (1 + inflation)^years
