What Is an Annuity Due and How Does It Work? đź’°

An annuity due is a stream of equal payments made at the beginning of each period, rather than at the end. This timing difference—though it sounds small—affects how much money you actually receive or owe over time.

To understand why timing matters, compare it to a regular annuity, where payments arrive at the end of each period. With an annuity due, you get your money sooner, which means it has more time to earn interest if you're investing it, or you pay down debt faster if you're making payments.

The Core Difference: Timing Is Everything

Most everyday financial arrangements—mortgages, car loans, rent—involve ordinary annuities, where payment happens at the end of the period. But certain situations use annuities due:

  • Lease payments (you pay at the start of the month to use the space for that month)
  • Insurance premiums (typically due upfront before coverage begins)
  • Pension or structured settlement payouts (some plans pay at period start)
  • Lottery winnings distributed in installments (often annuities due)

How the Math Works

Because payments arrive earlier with an annuity due, the present value and future value of that stream are mathematically higher than an ordinary annuity with the same payment amount and interest rate.

Key variables that shape the outcome:

  • Payment amount — How much each installment is
  • Interest rate or discount rate — What the money could earn (or what it's worth today)
  • Number of periods — How many payments you'll receive or make
  • Inflation — Whether your purchasing power changes over the life of the annuity

Two people with identical payment amounts and time horizons may experience very different real outcomes depending on interest rates at the time the annuity is structured and whether the payments are fixed or adjust over time.

Annuity Due vs. Ordinary Annuity: What Changes

FactorAnnuity DueOrdinary Annuity
Payment timingBeginning of periodEnd of period
Present valueHigher (money sooner)Lower
Future valueHigher (more earning time)Lower
Common usesLeases, insurance, some pensionsMortgages, bonds, most loans
Calculation factorMultiplied by (1 + interest rate)No adjustment

When This Distinction Matters Most

The timing difference has the largest impact when:

  • Interest rates are high — Earlier money is worth more when it can earn substantial returns
  • The annuity is long-term — Small per-period differences compound over years or decades
  • You're comparing offers — Two annuities that appear similar may have different structures

For a short-term annuity with low interest rates, the difference between due and ordinary might be negligible. For a 20-year pension or structured settlement at higher rates, it could mean thousands of dollars.

What You Should Evaluate

If you're considering or receiving an annuity (whether due or ordinary), the key questions depend on your own circumstances:

  • Does the payment schedule match your needs? (Do you need money at the beginning or end of each period?)
  • What interest or growth rate is assumed? (Is it fixed, variable, or based on market performance?)
  • Are there fees or adjustments that affect the real value you receive?
  • How does inflation affect purchasing power over the life of the annuity?
  • What happens if you need the money early? (Are there surrender charges or withdrawal restrictions?)

A financial advisor or tax professional familiar with your full situation can help assess whether an annuity due structure actually serves your goals—or whether an ordinary annuity, lump sum, or other approach would be better for you.
