Example Calculation

Suppose you want to save $500 per month for 10 years at an interest rate of 6% per year, compounded monthly. You want to calculate the future value for an ordinary annuity.

Step 1: Calculate Future Value (FV)
Using the formula:FV=Payment×(1+rate)periods−1rateFV = Payment \times \frac{(1 + rate)^{periods} - 1}{rate}FV=Payment×rate(1+rate)periods−1​

  • Payment = $500
  • Rate = 0.06 / 12 = 0.005
  • Periods = 10 × 12 = 120

FV=500×(1+0.005)120−10.005=500×160.75≈80,375FV = 500 \times \frac{(1 + 0.005)^{120} - 1}{0.005} = 500 \times 160.75 \approx 80,375FV=500×0.005(1+0.005)120−1​=500×160.75≈80,375

Step 2: Total ContributionsTotalPaid=Payment×Periods=500×120=60,000Total Paid = Payment \times Periods = 500 \times 120 = 60,000TotalPaid=Payment×Periods=500×120=60,000

Step 3: Interest EarnedInterest=FV−TotalPaid=80,375−60,000=20,375Interest = FV - Total Paid = 80,375 - 60,000 = 20,375Interest=FV−TotalPaid=80,375−60,000=20,375

So, after 10 years, your annuity will grow to $80,375, with $20,375 earned as interest.
