hat is an Annuity Due?

An annuity due is a series of equal payments made at the start of each period. This is different from an ordinary annuity, where payments occur at the end of each period.

For example:

  • Annuity Due: Paying rent at the beginning of the month.
  • Ordinary Annuity: Receiving a salary at the end of the month.

Because payments in an annuity due are made earlier, they earn more interest compared to an ordinary annuity. This makes them especially important in retirement planning, leases, or loan repayments.

How to Use the Annuity Due Calculator

Using this calculator is simple and requires just three steps:

  1. Enter Payment per Period
    Input the fixed amount you plan to pay each period (e.g., monthly deposit).
  2. Enter Interest Rate
    Provide the interest rate per period (e.g., monthly interest rate if compounding is monthly).
  3. Enter Number of Periods
    Input the number of periods (e.g., number of months or years).

Finally, click “Calculate” to see the results:

  • Future Value (FV)
  • Total Payments
  • Total Interest

Formula Behind the Calculator

The future value of an annuity due is calculated using this formula: FV=P×((1+r)n−1r)×(1+r)FV = P \times \left( \frac{(1 + r)^n - 1}{r} \right) \times (1 + r)FV=P×(r(1+r)n−1​)×(1+r)

Where:

  • FVFVFV = Future Value of the annuity
  • PPP = Payment per period
  • rrr = Interest rate per period
  • nnn = Number of periods

If the interest rate is 0%, the formula simplifies to: FV=P×nFV = P \times nFV=P×n

Example of Annuity Due Calculation

Example 1:

  • Payment per period = $500
  • Interest rate = 5% annually
  • Number of periods = 10 years

Calculation: FV=500×((1+0.05)10−10.05)×(1+0.05)FV = 500 \times \left( \frac{(1+0.05)^{10} - 1}{0.05} \right) \times (1+0.05)FV=500×(0.05(1+0.05)10−1​)×(1+0.05) FV=500×12.578×1.05=$6,617.79FV = 500 \times 12.578 \times 1.05 = \$6,617.79FV=500×12.578×1.05=$6,617.79

  • Future Value = $6,617.79
  • Total Payments = $5,000
  • Total Interest = $1,617.79

This means that by depositing $500 annually for 10 years at 5% interest, you’ll accumulate $6,617.79.
