Annuity Calculator

Q: Is this an annuity quote?

No. Actual annuity products can include mortality credits, guarantees, riders, fees and insurer-specific terms.

Q: What does payment timing change?

Beginning-of-period payments occur sooner, so the modeled amount differs from an end-of-period annuity.

Q: Are taxes and surrender charges included?

No. Contract expenses, taxes and surrender provisions are not modeled.

Q: Are calculator results financial advice?

No. Results are educational estimates and do not replace personalized financial, investment, tax, legal or insurance advice.

Q: Do results clear after I edit an input?

Yes. A displayed result is hidden as soon as an input changes so an old answer is not mistaken for a current calculation.

Q: Can I use the calculator on a phone?

Yes. The page and result panel are responsive for phones, tablets and desktop screens.
