Use this calculator for early planning and comparing scenarios. It shows the mathematical relationship between principal, interest rates, and payments. When you're ready to purchase, get quotes from actual insurance companies, as they factor in your age, health, and current market rates, which can significantly affect your actual payments.

The calculator uses the standard annuity formula to provide mathematically accurate results based on your inputs. However, real annuity rates from insurance companies may vary based on market conditions, your age, health status, and specific product features. Use these results as estimates for planning purposes.

The bar chart displays your annuity's starting balance (in dark blue) and closing balance (in green) for each year. This visual representation helps you see how your principal decreases over time as you receive payments while still earning interest.

The interest rate depends on current market conditions and varies by annuity provider and type. When interest rates go up (like bond yields or Federal Reserve rates), annuity rates typically increase too. When rates drop, annuity rates follow. For planning purposes, try calculating with a range — for example, 4%, 5%, and 6% — to see how different rates affect your payments. When you're ready to purchase, get quotes from multiple insurance companies to see what rates they're actually offering.

Work backwards with the calculator! Try different starting principal amounts until you reach your desired monthly payment. For example, at 5% interest over 20 years, you would need approximately $155,000 to generate $1,000 per month.

Yes, slightly! Annual payments result in more total money than monthly payments over the annuity term. This is because the full amount stays invested for a longer period, earning more interest before being withdrawn. For example, with $100,000 at 6% over 10 years, monthly payments total about $133,200, while annual payments total about $135,900 — a difference of about 2%. The difference is usually small, so choose based on your budget needs rather than trying to maximize this effect.

Most people prefer monthly payments, as they align with regular expenses, such as rent and utilities. However, less frequent payments (quarterly or annual) leave more money in the annuity longer, earning slightly more interest. Keep in mind that not all insurance companies offer every payment frequency, so be sure to check with providers about available options when comparing quotes.

Buying multiple smaller annuities over time (called "laddering") is a strategy worth considering instead of one large purchase. This spreads your risk across different interest rate environments — if rates rise, your next purchase benefits; if they fall, you've locked in earlier rates. It also allows you to diversify across insurance companies (reducing counterparty risk) and provides flexibility to adjust as your needs change. For example, instead of investing $200,000 at once, consider $50,000 now, $50,000 in 2 years, and so on.

Run multiple scenarios! Try different principal amounts, interest rates, payout periods, and payment frequencies to see how each variable affects your income. This helps you understand trade-offs before speaking with insurance providers. For example, you might discover that choosing a 15-year term instead of 20 years significantly increases your monthly payment while still providing long-term security.
