The Numbers You Need to Hit Before Leaving Work for Good
Scenario
You’re contributing to a 403(b)—maybe as a teacher, nonprofit worker, or hospital employee—and you want to know how much you need in your 403(b) to retire comfortably. The answer depends on your age, lifestyle goals, other assets (like pensions or Social Security), and when you plan to retire.
Here are the key benchmarks and strategies to find your number:
Multiply Your Annual Expenses by 25
- Target: 25x your yearly expenses
This is based on the 4% rule: to withdraw 4% per year without running out of money.
- ✔ Simple and widely used
- ✔ Works for conservative planners
- ✘ Assumes stable market returns
- ✘ Doesn’t account for healthcare shocks or inflation
Who Needs It: DIY retirees without pensions
Who Doesn’t: High-net-worth individuals with annuity or rental income
Helpful Add-on: Consider a fixed indexed annuity with a Guaranteed Lifetime Withdrawal Benefit (GLWB) to replace the 4% rule with higher, contractually guaranteed payouts for life.
Multiply Your Desired Annual Income by 20
- Target: 20x your retirement income gap
Use this if Social Security or a pension covers part of your income needs. Multiply the gap by 20 to get the amount your 403(b) must cover.
- ✔ Customizable to your real needs
- ✔ Encourages accounting for multiple income streams
- ✘ Can be inaccurate without knowing true expenses
- ✘ Requires Social Security estimate
Who Needs It: Those with pensions (e.g., teachers in TRS)
Who Doesn’t: People relying only on personal savings
Also consider: A QLAC (Qualified Longevity Annuity Contract) can defer RMDs and fill late-life income gaps efficiently.
Aim for a 403(b) Balance of 10–12x Your Final Salary
- Target: 10–12x annual salary by retirement
Fidelity’s rule of thumb suggests you save:
- 1x salary by age 30
- 3x by 40
- 6x by 50
- 8x by 60
- 10–12x by 67
- ✔ Easy to follow
- ✔ Based on actual salaries
- ✘ Doesn’t factor in pensions or annuities
- ✘ May overestimate for low spenders
Who Needs It: Early-career professionals looking for simple milestones
Who Doesn’t: People with large non-403(b) assets
Helpful Tip: You can reduce how much you need in your 403(b) by setting up a deferred income annuity that kicks in later in life.
Use a Retirement Income Calculator
- Target: Income goal minus fixed sources = 403(b) withdrawal need
Online tools let you enter Social Security, expenses, and 403(b) balances to simulate how long your money lasts.
- ✔ Tailored to your real numbers
- ✔ Can adjust for inflation, tax, and market returns
- ✘ Quality varies by tool
- ✘ May not factor in annuity strategies
Who Needs It: Mid-to-late career savers
Who Doesn’t: People not ready to dive into specifics
Helpful Add-on: Try the annuity with GLWB calculator to compare guaranteed income vs. the 4% rule. You can reverse engineer to see if you have enough to retire.
Let an Annuity Cover Your Base Income
- Target: Cover fixed expenses using annuities, then invest the rest
Instead of a withdrawal rate, buy a fixed indexed annuity with GLWB to guarantee a monthly income for life—even if your 403(b) runs out. There is no more efficient way to spend your 403(b) in retirement than a GLWB.
- ✔ Guarantees income for life.
- ✔ Pays 5–8% annually depending on age
- ✔ Inflation-resistant if structured right
- ✘ Irreversible decisions
- ✘ Requires upfront commitment
Who Needs It: Risk-averse retirees or those without pensions
Who Doesn’t: High-income investors are comfortable with market risk
Also consider: Pairing with life insurance if leaving a legacy matters
Final Thought
There’s no magic number—just the right number for your plan. Whether you need $500K or $1.5M in your 403(b) depends on what you want retirement to look like and whether you want your money to last or to grow.
