How It Works
Employees at non-profits and schools can use this tool to project how their 403(b) balance might grow over time. Those projections are easier to read against the 2026 limits: elective deferrals are capped at $24,500, and workers who are 50 or older can add a catch-up contribution of $8,000 on top of that, which together set the ceiling on how much you can put away each year.
The projection works one year at a time. Your yearly contribution is your salary times your contribution percentage, capped at the $24,500 limit (the calculator does not add the age-50 catch-up). The employer match is the match percentage applied to your contribution, counting your contribution only up to the "match up to" share of salary. Each year the two amounts are added to the balance at the start of the year and the total then grows by your expected return, so the account compounds once a year, starting from any balance you already have.
Any projected return here is hypothetical, and real investment performance can swing well above or below it. Inflation quietly eats into what your future balance will actually buy, so it is worth setting savings targets with that erosion in mind. Employer matching also deserves attention, since those contributions can meaningfully enlarge the balance you end up with at retirement.
Example: Sarah's 403(b) Growth
- 1 Sarah, a 35-year-old teacher earning $60,000, contributes 20% of her salary ($12,000 a year, or $1,000 a month) to her 403(b), starting from a $0 balance. Her employer matches 50% of her contributions up to 6% of salary. She assumes a 7% annual return and plans to retire at 65, 30 years away.
- 2 Employer match: her contribution counts only up to 6% of salary, $60,000 × 6% = $3,600, and the employer adds 50% of that, $1,800 a year ($150 a month). Total going in: $12,000 + $1,800 = $13,800 a year, or $414,000 over 30 years.
- 3 Growth: each year's $13,800 is added at the start of the year and the balance grows 7%. After year 1: $13,800 × 1.07 = $14,766. After year 2: ($14,766 + $13,800) × 1.07 = $30,565.62. After 30 years the calculator shows about $1,394,808, of which about $980,808 is investment growth.
- 4 Her own contributions alone would grow to about $1,212,876, so the $1,800-a-year match adds roughly $181,931 by age 65. The projection assumes a steady 7% every year; real returns will vary.
