How It Works

An annuity converts a pile of savings into a stream of income, and the central question is usually one of two things: how much monthly income a given lump sum will buy, or how large a lump sum you need to fund the income you want. Because interest rates and the broader economic landscape keep shifting, the answers change from year to year, which makes it worth running the numbers fresh for 2026 before committing any retirement assets.

The projections here lean on actuarial principles, adjusting for current market conditions and the annuity type you choose, whether immediate, deferred, fixed, or variable. An immediate fixed annuity, for instance, weighs prevailing interest rates against your age and life expectancy to set a guaranteed payment. Ask instead for the lump sum behind a target income and the same machinery runs in reverse, solving for the principal those variables imply.

Two forces can quietly erode what you actually keep. Inflation chips away at the buying power of a fixed payment over time, and variable annuities expose your income to investment risk, so weigh your own tolerance honestly. Fees and surrender charges deserve the same scrutiny, since they cut into net income more than most people expect. Treat these figures as a starting point and confirm with a financial advisor that an annuity fits your wider goals and tax picture.

Example: Securing a $5,000 Monthly Income

  1. 1 Let's say Sarah, a 65-year-old, wants to receive a guaranteed $5,000 per month in 2026 from an immediate fixed annuity. She has a lump sum available and wants to know how much she needs to invest.
  2. 2 Inputting her age (65), desired monthly income ($5,000), and assuming an average payout rate for a fixed immediate annuity in 2026 (e.g., 6.5% annually for a single life, non-inflation-adjusted annuity), the calculator works backward. It determines the lump sum required to generate this income over her projected lifespan, considering current mortality tables and interest rate environments.
  3. 3 Based on these inputs, the calculator estimates Sarah would need a lump sum of approximately $923,077 to secure a $5,000 monthly income for life, starting in 2026. This value reflects the present value of all future payments, discounted by the annuity's effective interest rate.
  4. 4 This means Sarah would need to invest nearly $1 million to achieve her desired income target. This calculation provides a clear financial goal, allowing her to assess if her current savings are sufficient or if further adjustments to her retirement plan are necessary. It's important to note that actual rates can vary by provider and specific annuity features.

Frequently Asked Questions

How much does a $100,000 annuity pay per month?
A $100,000 immediate annuity for a 65-year-old pays roughly $550-$650 per month in 2026, depending on the insurance company, type of annuity, and whether you choose a single-life or joint payout.
Are annuity payments taxable?
It depends on how you funded the annuity. If purchased with pre-tax money (like a traditional IRA), the entire payment is taxable. If purchased with after-tax money, only the earnings portion is taxed as ordinary income.
What is the difference between immediate and deferred annuities?
An immediate annuity starts paying income within a year of purchase. A deferred annuity grows tax-deferred for years before converting to income, typically offering higher future payments.
