Are You Leaving Dollars on the Table?
If you are not contributing enough to capture the maximum employer match, you are literally turning down part of your compensation. For many plans, this can mean thousands of dollars per year in lost employer contributions — money that would compound over decades.
Use the policy details and calculator below to find out exactly how much you need to contribute to capture every dollar of employer matching.
MARATHON PETROLEUM THRIFT PLAN Contribution & Match Policy
1. Employee Contribution Rates: Employees can contribute up to 75 percent of eligible pay to the plan.
2. Employer Match/Contribution Conditions: The employer matches eligible participant contributions up to a maximum of 6 percent of eligible pay at the rate of $1.17 per dollar contributed.
3. Vesting Schedule/Eligibility: Participants are fully and immediately vested in their contributions and Company matching contributions made on or after January 1, 2016. For Company matching contributions made prior to January 1, 2016, participants generally become fully vested after three years of service, upon retirement, death, disability, or attainment of age 65.
4. Roth 401(k) Contribution: Yes, the plan allows Roth contributions.
MARATHON PETROLEUM THRIFT PLAN Maximum Employer Match Calculator
This calculator helps participants of MARATHON PETROLEUM THRIFT PLAN to calculate the minimal bi-weekly contribution that would generate the maximum employer match allowed. It takes into account IRS annual contribution limits. Please update the annual contribution limits below if they are outdated.
2025 IRS 401(k) Contribution Limits
The IRS sets annual limits on how much you and your employer can contribute to a 401(k) plan. Knowing these limits helps you maximize tax-advantaged savings. Here are the current limits:
| 2024 | 2025 | |
|---|---|---|
| Employee elective deferrals (pretax + Roth) | $23,000 | $23,500 |
| Employee + employer contributions combined | $69,000 | $70,000 |
| Catch-up contributions (age 50+) | $7,500 | $7,500 |
| Enhanced catch-up (ages 60–63, SECURE 2.0) | N/A | $11,250 |
The power of maxing out: If you contribute the full $23,500 annually for 20 years at a 10% average annual return, you would accumulate approximately $1,505,256. If you can maximize the combined employee+employer limit of $70,000 per year, that grows to roughly $4,480,385 over the same period — more than triple.
