Salary Contribution Calculator
A 401(k) match is the closest thing to free money in personal finance: many employers add 50 cents for every dollar you contribute, up to a cap. Yet most people guess at their contribution percentage without knowing what it buys them. This salary contribution calculator turns your salary, contribution rate, and employer match into annual dollars, per-paycheck amounts, and your total savings rate measured against the 15% guideline.
Quick Answer
On a $75,000 salary with a 6% contribution and a 50% employer match up to 6%, you put in $4,500 a year ($173.08 per biweekly paycheck) and your employer adds $2,250, for $6,750 total. That is a 9% total savings rate, below the 15% guideline, and it uses 18.4% of the $24,500 employee limit for 2026.
- Always capture the full match first. A 50% match up to 6% is an instant 50% return on those dollars. Contributing 3% instead of 6% on $75,000 leaves $1,125 of employer money unclaimed every year.
- The 15% guideline includes the match. Your 6% plus the employer's 3% puts you at 9%; closing the gap means raising your own rate, not finding a better match.
- The $24,500 limit is yours alone. Employer matching dollars do not count against your elective deferral limit; they count toward the separate $72,000 total additions limit.
- One percent a year is painless. Auto-escalation, raising your rate 1% annually, closes a 6-point gap in six years without a noticeable lifestyle change.
What each contribution level buys on $75,000
Same salary, same 50% match up to 6%. Notice how the match stops growing once your contribution passes the 6% cap: every dollar above it is yours alone.
| Your rate | You contribute | Employer match | Total per year | Savings rate |
|---|---|---|---|---|
| 3% | $2,250 | $1,125 | $3,375 | 4.5% |
| 6% | $4,500 | $2,250 | $6,750 | 9.0% |
| 10% | $7,500 | $2,250 | $9,750 | 13.0% |
| 15% | $11,250 | $2,250 | $13,500 | 18.0% |
The jump from 6% to 10% costs $115.38 more per biweekly paycheck and adds $3,000 a year to the account, all of it yours. That is the cheapest way to close the gap to 15%: the match is already maxed, so the remaining 6 points come from you.

Pre-tax vs. Roth: the real trade-off
Most plans now offer both traditional (pre-tax) and Roth (after-tax) contributions under the same $24,500 limit. The employer match always goes in pre-tax. Which one you pick is a bet on your future tax rate.
- Lowers taxable income now; the $4,500 example saves roughly $990 of federal tax at a 22% marginal rate
- Better if you expect a lower tax rate in retirement
- Required minimum distributions eventually apply
- No deduction now, but qualified withdrawals are tax-free in retirement
- Better if you expect higher rates later or are early in your career
- No tax bill on decades of growth
A common split strategy: take the pre-tax deduction while you are in a high bracket, then shift toward Roth in lower-income years. Either way, the match math above does not change. For the monthly view of any of these figures, use our annual to monthly income calculator.
What contribution calculators get wrong
The standard failure is showing your contribution and stopping, which hides the two numbers that actually drive decisions: the match captured or missed, and the total savings rate against the 15% guideline. Others apply the match percentage to your whole contribution instead of capping it, inventing employer money above the cap. Many still quote the $23,500 limit from 2025 instead of $24,500 for 2026, and almost none flag that the match does not count against your personal limit, which leads people to under-contribute out of a misplaced fear of exceeding it. This calculator caps the match correctly, separates your dollars from the employer's, and measures the result against the benchmarks that matter.
Catch-up contributions and the two-job trap
Two limits sit outside this calculator, and both change the answer for older savers and for anyone with two jobs. First, catch-up contributions: for 2026, savers aged 50 and over may add $8,000 on top of the $24,500 elective deferral limit, for $32,500 in total, and savers aged 60 to 63 may add $11,250 instead, for $35,750 in total, where the plan allows it. The tool does not model catch-ups, so a saver over 50 who stops at the $24,500 share-of-limit line is understating their real headroom. Second, the $24,500 limit is per person, not per plan: deferrals to two employers add together, and neither payroll system sees the other. Track the combined total yourself, and if you exceed it, ask the plan administrator about correcting the excess before the April 15 deadline described in the questions below.
