Annuity Income Withdrawal Schedule Planner

Model a withdrawal schedule from an annuity account value using a constant withdrawal amount, payment frequency, assumed annual growth rate, and planning horizon. This planner is most relevant to annuity contracts that have an accessible account value and scheduled withdrawals, not to an immediate income annuity with no comparable withdrawable balance.

The calculation applies growth between withdrawals and tracks how many full payments the modeled balance can support. It also reports total withdrawals, estimated growth earned, and the ending account value. Contract charges, surrender schedules, rider rules, market-value adjustments, taxes, and insurer-specific guarantees are not included, so actual contract values can differ materially from the projection.

1. Enter the current value
Use the account value that is actually available for the withdrawal strategy you want to test.

2. Set a payment amount
Enter the amount you plan to withdraw at each scheduled payment.

3. Set payment frequency
Choose how many withdrawals the model should apply each year.

4. Enter an assumed growth rate
Use a net annual growth assumption appropriate to the contract scenario you are testing.

5. Choose the horizon
Review whether the modeled value survives the full period and how many withdrawals are funded.

Periodic growth rate = annual growth rate / payments per year Next value = prior value × (1 + periodic growth rate) − withdrawal Total withdrawals = withdrawal × funded payments Estimated growth = ending value + total withdrawals − starting value

This is a deterministic account-value projection. It does not model variable returns, contract fees, surrender charges, guaranteed benefit bases, or tax effects.

What the result means

A positive ending value means the modeled annuity account still has value after all scheduled withdrawals in the selected horizon.

If the modeled value cannot support the next full withdrawal, the calculator stops the schedule and reports the number of payments funded.

Given

  • Starting annuity value: $200,000
  • Monthly withdrawal: $1,500
  • 12 payments per year
  • Assumed annual growth: 4%
  • Planning horizon: 10 years

Calculation
Periodic growth rate = 4% ÷ 12 = 0.3333%
First update = $200,000 × 1.003333 − $1,500 ≈ $199,167
Repeat the same growth-then-withdrawal step for 120 monthly periods.

Result
The modeled account retains a positive ending value after the 10-year schedule.

The result can be rerun with a larger withdrawal or lower growth rate to stress-test the plan.

Can I use this for an immediate annuity payment stream?

Only with caution. The planner assumes there is an account value that grows and is reduced by withdrawals, which may not describe an immediate income annuity.

Does the growth rate include contract fees?

Only if you enter a rate that is already net of the fees and charges you expect. The calculator does not subtract separate rider, mortality, expense, or surrender charges.

What does “payments funded” tell me?

It counts the number of full scheduled withdrawals the modeled balance can make before the account is exhausted or the planning horizon ends.

Are taxes deducted from withdrawals?

No. The schedule is shown on a pre-tax account-value basis. Taxable portions and withholding depend on the contract and individual circumstances.

Why might my insurer statement differ from this projection?

Real annuity values can reflect credited-rate rules, market performance, fees, surrender terms, guarantees, and transaction timing that this simplified model does not reproduce.
