The Variable Annuity Calculator simulates a variable annuity contract by combining a principal, periodic contributions, expected market return, annual fees, and scheduled withdrawals. It produces the projected ending balance, total fees, total withdrawn, and the year (if any) when the account is depleted.
How to Use Variable Annuity Calculator
- Enter initial principal and per-period contribution amount.
- Select contribution frequency (monthly, quarterly, or annual).
- Set the expected annual return and annual fee rate.
- Provide the withdrawal start year and per-period withdrawal amount.
- Review the projected ending balance, fees paid, and any depletion year.
Formula & Theory - Variable Annuity Calculator
For each period:
balance = (balance + contribution - withdrawal_if_started) × (1 + net_periodic_return)
net_periodic_return = (annual_return - annual_fee) / frequency
Use Cases for Variable Annuity Calculator
- Stress-test a variable annuity before purchasing.
- Compare the impact of different fee levels on long-term returns.
