How to Use Annuity Payout Calculator
Quick Answer
Annuity monthly payout formula: PMT = PV × [r(1+r)^n] ÷ [(1+r)^n - 1]
Where: PV = present value (lump sum), r = monthly interest rate (annual rate ÷ 12), n = total number of payments (years × 12).
Example: $200,000 at 4% for 20 years. r = 0.04 ÷ 12 = 0.003333. n = 240. PMT ≈ $1,212 per month.
An annuity converts a lump sum of money into a guaranteed stream of regular payments over a fixed period or for life. Use the free Annuity Payout Calculator on CalConvs to find your monthly payout for any scenario.
How Annuities Work
| Type | Description |
|---|---|
| Fixed term annuity | Pays a fixed amount each month for a defined number of years. Payments stop at the end of the term. |
| Lifetime annuity | Pays every month for the rest of your life regardless of how long you live. Provides longevity insurance. |
| Deferred annuity | You pay in now. Payouts begin at a future date. Money grows in the accumulation phase. |
| Fixed annuity | Interest rate is guaranteed and fixed for the term. Predictable and low risk. |
| Variable annuity | Payments vary with investment performance. Higher potential returns but more uncertainty. |

Under the National Pension System (NPS), at retirement (age 60) at least 40% of the accumulated corpus must be used to purchase an annuity from an IRDAI-registered insurer. The remaining 60% can be withdrawn tax-free. The Employee Provident Fund (EPF) can be withdrawn as a lump sum at retirement.
Pakistan: EOBI and Private Pension
The EOBI provides a modest monthly pension. Under the Voluntary Pension System (VPS) launched by SECP, contributions can be converted to an annuity at retirement. NSS Defence Savings Certificates provide a structured withdrawal option.
Annuity vs Drawdown

Frequently Asked Questions
How much annuity does £100,000 GBP buy?
In the UK in 2024, £100,000 buys approximately £6,000 to £7,500 per year as a single life annuity for a 65-year-old, depending on the insurer and type chosen. Use the Annuity Payout Calculator to model different rates and terms.
What is a good annuity rate?
Annuity rates rise with interest rates. In 2024, UK annuity rates are significantly better than in 2020 to 2022 due to higher gilt yields. A rate that provides 6 to 7% of the purchase price annually is considered good in the current UK environment.
Can I outlive an annuity?
With a fixed-term annuity, payments stop at the end of the term. With a lifetime annuity, payments continue until death. Choosing a lifetime annuity eliminates the longevity risk of outliving your savings.
