Future Value of Retirement Savings (Compound Interest):

FV = P × (1 + r)t + PMT ×
(1 + r)t − 1r

Where:

FV = Future Value of Retirement Savings

P = Current savings

PMT = Monthly contribution

r = Monthly interest rate (annual rate ÷ 12)

t = Total months until retirement

Step-by-Step Worked Example

Example: Retirement Savings Projection

  • Current savings (P): $50,000
  • Monthly contribution (PMT): $500
  • Annual interest rate: 6% → Monthly rate: 0.06 ÷ 12 = 0.005
  • Years until retirement: 30 → Total months: 30 × 12 = 360
FV = 50000 × (1 + 0.005)360 + 500 ×
(1 + 0.005)360 − 10.005
≈ 648,000 + 780,000 ≈ 1,428,000

Result: Estimated retirement savings = ontouchstart="",428,000
