A fixed annuity quoting a “guaranteed” rate can look unremarkable next to a taxable alternative advertising a higher number — until you run the tax math. Here’s a simple way to show clients what a tax-deferred guarantee is actually worth.
Key takeaways
- Clients anchor on the headline rate, not the after-tax outcome — that’s where taxable alternatives look falsely competitive.
- On a $100,000 deposit, the tax-deferred annuity compounds to roughly $116,758 by year three at 5.30%.
- Tying the comparison to a client’s actual tax bracket and time horizon makes the tax-equivalent yield conversation most persuasive.
A 5.30% tax-deferred annuity guarantee is equivalent to an 8.15% return on a fully taxable investment at a 35% tax bracket.
The comparison clients don’t usually see
Say a client is deciding between a tax-deferred fixed annuity guaranteeing 5.30% for three years, and a taxable investment. Assuming a 35% tax bracket, that 5.30% tax-deferred guarantee is equivalent to an 8.15% return on a fully taxable investment. Most clients — and plenty of advisors — never see that comparison laid out side by side.
Running the numbers
On a $100,000 deposit, the tax-deferred annuity at 5.30% grows to roughly $105,300 in year one, $110,881 by year two, and $116,758 by year three. A taxable account would need to earn 8.15% just to keep pace after taxes — and that’s before accounting for the annual tax drag on a taxable account, which compounds the disadvantage year over year.
Why this comparison matters for the conversation
Clients tend to anchor on the headline rate, not the after-tax outcome. When a taxable option quotes a higher number, it’s easy for a client to assume it’s the better deal. Showing the tax-equivalent yield reframes the conversation around what actually lands in the client’s pocket, not just the rate on paper.
How to use this with clients
This kind of side-by-side math is most persuasive when it’s tied to a client’s actual tax bracket and time horizon, since both change the tax-equivalent yield. It’s also a natural opening to talk about how tax deferral compounds over multiyear guarantee periods, and where a fixed annuity might fit alongside other retirement and legacy planning tools.
If you have a client comparing a fixed annuity to a taxable alternative and want help running the actual numbers for their bracket and time horizon, that’s a conversation we can help you have.
Frequently asked questions
What is tax-equivalent yield?
It’s the rate a taxable investment would need to earn to match the after-tax return of a tax-deferred vehicle like a fixed annuity, given a client’s tax bracket. A higher headline rate on a taxable product doesn’t always mean a better after-tax outcome.
Does the tax-equivalent yield change with a client’s tax bracket?
Yes. The higher a client’s tax bracket, the more valuable tax deferral becomes, and the higher the taxable-equivalent yield needed to match a given tax-deferred guarantee.
