How much should I contribute to my 401(k)? (2026)

Contribute at least enough to capture your full employer match. From there, work toward saving 15% of pre-tax income across all retirement accounts (401(k) + IRA + HSA). The 2026 cap is $24,500.

The right percentage depends on three things:your match formula, what you can sustainably afford after rent and bills, and where the 401(k) sits in your full retirement-savings stack. There's a clear order of operations and a target number most people should aim at.

This guide walks the order, shows what each contribution percentage actually does to your paycheck and retirement balance, and gives you a starting point you can ratchet up with each raise.

The two numbers that anchor the decision

The floor — get the full match. If your employer matches 50% on the first 6% you contribute, contributing 6% triggers a 3% bonus from them. Contributing less leaves free money on the table. Whatever percentage you need to capture every dollar of available match is your non-negotiable floor.

The target — 15% of pre-tax income.Across all retirement accounts. That includes the employer match. Most retirement-planning research, including Fidelity's widely-cited age-based benchmarks, points to roughly 15% as the rate that puts a typical worker on track to maintain their lifestyle in retirement.

The cap — $24,500 in 2026.That's the IRS employee deferral limit. If you can afford it, hitting the cap puts retirement savings on autopilot at the strongest possible level.

What each contribution rate actually does

Here's how four common contribution rates play out for a $75,000 earnerwith a 50%-on-the-first-6% match, projected to age 65, at a 7% real return.

The 3%-vs-6% gap is the most expensive mistake in personal finance.Doubling from 3% to 6% doesn't just double your contribution — it also doubles the match, and the combined effect doubles your retirement balance.

The order of operations

For most workers, the right sequence is fixed. Follow it in order, stop when you run out of money to save.

1. Contribute to the 401(k) up to the full match. Free money.
2. Pay off high-interest debt (credit cards, anything over ~8%) before adding more retirement contributions. A 22% APR balance crushes a 7% expected market return.
3. Max your IRA. $7,500 in 2026. Usually a Roth IRA unless your bracket is high. See Roth vs. Traditional IRA.
4. Max your HSA if you're on a high-deductible health plan. Triple tax advantage — uniquely powerful.
5. Back to the 401(k). Increase your contribution rate until you hit 15% total, or the $24,500 cap, whichever you can sustain.
6. Taxable brokerage for anything beyond.

The full reasoning for this order lives in our deeper guide: 401(k) vs. IRA: which should you fund first.

What if 15% feels impossible?

Most people don't start at 15%. They climb there. Two strategies do most of the work.

• The annual 1% ratchet.Increase your contribution rate by 1 percentage point every January. The pay raise mostly absorbs the drop in take-home; in five years you've gone from 6% to 11% without feeling it.
• Save half of every raise. If you get a 4% raise, increase your contribution by 2 percentage points. Lifestyle creep slows, retirement balance jumps.

Auto-escalation is built into most workplace plans now — opt in once and the 1% ratchet happens automatically.

What does maxing out look like?

$24,500 is roughly $943 per biweekly paycheckin pre-tax dollars. For a $120,000 earner, that's about a 20% contribution rate. Hitting the cap is a stretch goal — typically a household decision rather than a starting point.

Why max out? A maxed 401(k) plus a maxed Roth IRA plus a modest HSA puts you at roughly $34,000 a year in tax-advantaged retirement savings. Over 25 years at 7% real, that compounds to roughly $2.15 million. Few people regret hitting that number; many regret coasting at 6%.

Roth 401(k) vs. Traditional 401(k)

Roth contributions are after-tax; Traditional contributions are pre-tax.The right split depends on your bracket today vs. your expected bracket in retirement.

The employer match is always made in Traditional (pre-tax) dollars,regardless of which type you choose for your own contributions. So your account ends up with both flavors of money — Roth principal grows tax-free, Traditional principal is tax-deferred.

A simple action plan

1. Run the match calculator — confirm your match formula and the percentage you need to contribute. 401(k) match calculator.
2. Log into your 401(k) provider and set your contribution to that percentage today.
3. Open or fund your Roth IRA to the $7,500 cap (if eligible). See Roth IRA contribution limits 2026.
4. Set auto-escalation to add 1% to your 401(k) rate every January until you hit 15% total or the cap.
5. Don't check the balance often. The market will swing. Your contribution rate is what compounds.

The bottom line

Floor: enough to get the full match. Target: 15% of pre-tax income. Ceiling: the $24,500 IRS cap. Most people should start at the floor, ratchet up 1% each January, and reroute IRA-eligible dollars to a Roth IRA before pushing the 401(k) past the match.

The exact percentage matters less than starting today and increasing each year. A decade of consistent contributions, even at modest rates, beats a perfect plan that never gets executed.
