> The 403(b) calculator projects your 403(b) retirement plan balance at retirement from your salary, contribution rate, employer match, current balance, expected return and salary increases – with the 2026 IRS contribution limits.

## Inputs

- Annual salary
- Your contribution (%)
- Employer match (%)
- Employer match limit (% of salary) (%)
- Current age
- Retirement age
- Current 403(b) balance
- Expected annual return (%)
- Annual salary increase (%)

## Results

- Years to retirement
- 2026 contribution limit for your age
- Your contribution this year
- Employer match this year
- Balance at retirement
- Your total contributions
- Employer's total contributions
- Investment growth
- Yearly income at a 4% withdrawal rate

## Formula

```
Your yearly contribution = salary × contribution % (up to the IRS limit)
Employer match = salary × min(contribution %, match limit %) × match %
Balance at retirement = balance × (1 + r)^n + growing annuity of contributions, FV = C × ((1 + r)^n − (1 + g)^n) ÷ (r − g)
```

## Explanation

A 403(b) is the 401(k)-style plan for public schools, hospitals and non-profits. For 2026 you can defer up to $24,500, plus an $8,000 catch-up at age 50+ ($11,250 at ages 60–63). Long-serving employees may also have a special 15-year catch-up.

### What each result means

- **Years to retirement** = max([Retirement age] - [Current age], 0)
- **Your contribution this year** = min([Annual salary]×[Your contribution]÷100, [2026 contribution limit for your age])
- **Employer match this year** = [Annual salary]×min([Your contribution], [Employer match limit (% of salary)])÷100×[Employer match]÷100
- **Balance at retirement** = [Current 403(b) balance]×(1 + [Expected annual return]÷100)^[Years to retirement] + gfv([Expected annual return]÷100, [Years to retirement], [Your contribution this year] + [Employer match this year], [Annual salary increase]÷100, 0)
- **Investment growth** = [Balance at retirement] - [Current 403(b) balance] - [Your total contributions] - [Employer's total contributions]
- **Yearly income at a 4% withdrawal rate** = [Balance at retirement]×0.04
