📐 How annuities work

An annuity is a series of equal payments at regular intervals. Here are the key formulas:

Annuity formulas:

FV (Ordinary) = PMT × [ ((1+r)n - 1) / r ]
PV (Ordinary) = PMT × [ (1 - (1+r)-n) / r ]
  • PMT = Periodic payment amount
  • r = Interest rate per period
  • n = Number of payment periods
  • FV = Future Value (accumulated amount)
  • PV = Present Value (lump sum needed)
Example: $100,000 principal, 5% interest, 20 years
Annual payment (ordinary) = $8,024
Annual payment (annuity due) = $7,642

Key insight: Annuity due payments (at the beginning of each period) are worth more than ordinary annuity payments (at the end) because you get them sooner.

Factors Affecting Annuity Calculator Results

Initial Investment

The initial size of your deposit is critical. Investing a greater sum of money initially would result in a larger final figure through the process of compounding.

Regular Contributions

Regular periodic contributions increase the overall contribution of funds and enhance significant growth of long-term of an annuity based on an investment time period.

Interest Rate

Expected Annual return directly influences the growth of our investment. Generally, the higher the rate, the more value we expect to generate in the future.

Investment Duration

Longer investment terms allow the annuity time to mature. Compounding can increase the size of the annuity over the years.

Contribution Frequency

Depending on how often contributions are made monthly, quarterly or annually it may influence the final return since more frequent deposit may start earning interest sooner.

Type of Annuity

The period over which the annuity operates will determine whether it is an immediate or deferred annuity, when payments are made, and the manner in which accruals are accounted.

Compounding Frequency

Interest added (or compounded) in monthly, quarterly or annual periods will alter the total amount and an important choice to make to ensure you provide an accurate calculation estimate.
