How much should you contribute to a 401(k)? The latest official provider data does not produce one universal answer, but it does show how American workers are saving, how much employers add, and how contribution behavior changes with age.
This guide uses only first-party data from Fidelity and Vanguard. The two firms measure different plan populations and different dates, so their figures should be compared carefully rather than blended into one artificial average.
Quick answer: Fidelity reported an average employee 401(k) savings rate of 9.6% in Q1 2026 and a total savings rate of 14.4% when employer contributions were included. Vanguard reported an average employee deferral rate of 7.6% and an average total contribution rate of 12.1% for 2025. These are benchmarks—not personalized targets.
Average 401(k) contribution rates at a glance
| Measure | Fidelity | Vanguard |
|---|---|---|
| Employee contribution or deferral rate | 9.6% in Q1 2026 | 7.6% average in 2025 |
| Median employee deferral rate | Not reported in the cited Q1 table | 6.6% in 2025 |
| Employer contribution rate | 4.8% in Q1 2026 | Included in total contribution data |
| Total employee + employer rate | 14.4% in Q1 2026 | 12.1% average, 11.6% median in 2025 |
The figures are not directly interchangeable. Fidelity's Q1 2026 data covers 26,800 corporate defined contribution plans and 25.6 million participants as of March 31, 2026. Vanguard's 2026 report summarizes 2025 activity across 4.6 million participant accounts and approximately 1,300 plans.
What does “401(k) contribution rate” mean?
Several different measures are often described as a contribution rate:
- Employee deferral rate: The percentage of pay contributed by the worker.
- Employer contribution rate: The percentage added by the employer through a match or another contribution.
- Total savings rate: Employee and employer contributions combined.
- Elected deferral rate: The percentage a participant chooses, which may differ from the actual annual rate if the participant reaches the legal contribution limit.
- Automatic enrollment default rate: The percentage used when an employer enrolls a worker automatically.
A financial article can become misleading if it compares one of these measures with another without explaining the difference.
Fidelity: average total savings reached 14.4% in Q1 2026
Fidelity reported record contribution rates in the first quarter of 2026:
- The average employee savings rate reached 9.6%.
- The average employer contribution rate was 4.8%.
- The combined total savings rate reached 14.4%.
- 18% of participants increased their savings rate during the quarter.
- 85.4% of participants received an employer contribution.
Fidelity's average employee contribution amount was $3,120 in Q1 2026, while the average employer contribution amount was $2,080. These dollar amounts cover the quarter, not a full year.
The distinction matters. Presenting $3,120 as an annual average would be incorrect.
Vanguard: average and median employee deferral rates
Vanguard reported that participants contributed an average of 7.6% of income in 2025. The median participant deferral rate was 6.6%.
Including employer contributions:
- Average total contribution rate: 12.1%
- Median total contribution rate: 11.6%
Vanguard also reported that:
- 25% of participants deferred at least 10% of pay.
- 22% deferred less than 4%.
- 45% saw an increase in their elected deferral rate during 2025.
- 14% contributed the statutory maximum for 2025.
The average and median serve different purposes. The average is influenced more heavily by high savers, while the median describes the midpoint of participating accounts.
401(k) contribution rates by generation
Fidelity's Q1 2026 data shows a clear age-related pattern.
| Generation | Employee savings rate | Employer contribution rate | Combined rate |
|---|---|---|---|
| Gen Z | 7.5% | 4.0% | 11.5% |
| Millennials | 9.0% | 4.8% | 13.8% |
| Gen X | 10.5% | 5.2% | 15.7% |
| Baby Boomers | 12.2% | 5.1% | 17.3% |
| Overall | 9.6% | 4.8% | 14.4% |
The combined column is simple addition for comparison and matches Fidelity's reported overall total savings rate.
Older workers contribute more on average, but that does not mean every young worker is behind. Contribution rates are shaped by income, tenure, plan design, household costs, and proximity to retirement.
Vanguard contribution rates by age
Vanguard's 2025 average employee deferral rates also rose with age:
| Age group | Average employee deferral rate |
|---|---|
| Under 25 | 5.5% |
| 25–34 | 6.7% |
| 35–44 | 7.2% |
| 45–54 | 7.9% |
| 55–64 | 9.3% |
| 65+ | 10.1% |
These are participant averages, not recommendations. Older workers may be contributing more because they earn more, have fewer competing expenses, or are trying to increase savings before retirement.
How much do you need to contribute to receive the full employer match?
There is no single standard employer match.
Vanguard administered more than 100 match formulas in 2025. Among plans with single-tier or multitier matches:
- The average maximum promised match was 4.7% of pay.
- The median maximum promised match was 4.0% of pay.
- The average employee contribution needed to receive the full match was 6.4% of pay.
- The median employee contribution needed was 6.0%.
- About 8 in 10 plans required employees to contribute between 4.0% and 6.99% of pay to maximize the match.
The most common match formula in Vanguard's dataset was $0.50 for each $1 contributed on the first 6% of pay. That formula produces a maximum employer contribution equal to 3% of pay.
Fidelity reported a different most-popular formula on its platform: a 100% match on the first 3% of employee contributions and a 50% match on the next 2%.
Both examples show why workers should check their own plan documents rather than assume that a national average describes their employer.
Automatic enrollment can shape contribution behavior
Plan defaults influence how much people save.
Fidelity reported an average automatic enrollment default rate of 3.9% in Q1 2026. About one-third of plans defaulted automatically enrolled workers at 5% or more.
Vanguard found that automatic enrollment defaults have increased over time:
- 62% of automatic enrollment plans used a default of 4% or more in 2025.
- 31% used a default of 6% or more.
- 71% of automatic enrollment plans also included automatic annual increases.
Vanguard also found that when plans used a 6% automatic enrollment default, participants across all measured income groups had a median elected deferral rate of at least 7%.
That does not prove that 6% is right for everyone. It shows that plan design can materially influence saving behavior, especially when workers are unlikely to change the default.
Is the average contribution rate enough?
An average can describe behavior, but it cannot determine retirement readiness.
A contribution rate may be adequate for one person and insufficient for another because of differences in:
- current age;
- retirement date;
- existing savings;
- expected retirement spending;
- employer contributions;
- investment returns;
- Social Security or pension income;
- career interruptions;
- taxes and healthcare costs.
A 14.4% total savings rate may sound strong, but a worker starting late may need more. A younger worker who already has substantial savings may need less. The useful question is not “Am I at the average?” but “Does my current rate support my own retirement target?”

A practical contribution framework
A simple way to evaluate your contribution rate is to work through these steps:
- Capture the full employer match.
Determine the exact employee contribution required under your plan. - Separate employee and employer contributions.
Do not assume your own contribution rate equals your total savings rate. - Review the rate annually.
Consider increasing contributions after raises or when major expenses decline. - Compare progress with your retirement target.
A savings-rate benchmark is useful only when connected to a projected outcome. - Account for other retirement assets.
IRAs, pensions, taxable investments, and a spouse's savings may change the amount required in your current 401(k).
Why provider averages differ
Fidelity and Vanguard report different contribution rates because their datasets are different.
- They recordkeep different employers and industries.
- Their participant populations have different ages, incomes, and tenure.
- Fidelity's cited figures are from Q1 2026, while Vanguard's are for 2025.
- They may define or present savings measures differently.
- Automatic enrollment and employer contribution designs vary across plans.
For that reason, this article does not average the Fidelity and Vanguard percentages together.
Common mistakes when comparing contribution rates
Avoid these interpretation errors:
- Treating an employee rate as if it includes the employer match.
- Comparing a quarterly dollar contribution with an annual amount.
- Assuming the median and average describe the same participant.
- Treating an automatic enrollment default as a recommended savings target.
- Assuming one provider's participant population represents every American worker.
- Ignoring old 401(k)s, IRAs, pensions, or other retirement assets.
Bottom line
The latest official provider data suggests that many participating workers save between roughly 8% and 10% of pay themselves, with employer contributions lifting average total rates into the 12% to 14% range.
The clearest current figures are:
- Fidelity employee savings rate: 9.6%
- Fidelity total savings rate: 14.4%
- Vanguard average employee deferral rate: 7.6%
- Vanguard median employee deferral rate: 6.6%
- Vanguard average total contribution rate: 12.1%
- Vanguard median total contribution rate: 11.6%
These figures are useful benchmarks, but the right contribution rate depends on your retirement goal—not the average participant.

What is the average total 401(k) savings rate including employer contributions?
Fidelity reported a total 401(k) savings rate of 14.4% in Q1 2026. Vanguard reported an average total contribution rate of 12.1% for 2025.
What is the median 401(k) contribution rate?
Vanguard reported a median employee deferral rate of 6.6% and a median total contribution rate of 11.6% for 2025.
How much should I contribute to get the full employer match?
Vanguard reported that the average employee contribution required to maximize the employer match was 6.4% of pay, with a median of 6.0%. Your own plan may use a different formula.
Do employer contributions count toward my savings rate?
They count toward the total amount going into your retirement account, but they are separate from your employee deferral rate. It is useful to track both numbers.
Is a 10% employee contribution rate good?
A 10% employee contribution is above the average employee deferral rates reported by both Fidelity and Vanguard, but whether it is sufficient depends on your age, existing balance, retirement date, spending target, and employer contributions.
