401(k) Employer Match and Vesting: Read Your Plan

Separate your own retirement contributions from employer contributions and understand matching formulas, vesting schedules and job-change decisions. The examples below are explanatory, not product quotes or promises of approval, savings, coverage or investment performance.

Match and vesting answer different questions

An employer match explains how the employer contributes when the employee contributes. Vesting explains when employer-provided money becomes nonforfeitable. A person can receive matching deposits on statements but still forfeit an unvested portion after leaving.

Employees are always fully vested in their own contributions and related earnings. Employer contributions may vest immediately, gradually or after a cliff period, subject to federal minimum standards and the plan’s more generous terms. Safe-harbor and certain other plans can have different rules.

The Summary Plan Description and benefit statement should explain the formula, eligible pay, contribution deadlines, vesting service and forfeiture rules. Payroll settings alone cannot show the complete benefit.

Translate the plan into four numbers

Use current plan documents and year-to-date payroll records.

1. Employee contribution rate. Confirm traditional, Roth or other available deferral choices and current legal limits.
2. Match formula. Identify the employer percentage and the employee contribution needed to receive the available match.
3. Eligible compensation. Check whether bonuses, commissions or other pay are included.
4. Vested percentage. Determine credited service and the schedule that applies to employer money.
5. Timing rules. Ask whether each paycheck must include a contribution or whether the plan has a year-end true-up.

Illustrative match and vesting record

Assume a plan matches 50% of employee contributions up to 6% of eligible pay and uses a graded vesting schedule. Actual plans vary.

A job-change decision should also consider salary, health coverage, career opportunity and plan rules. Vesting is one factor, not a reason to remain in an unsafe or unsuitable job.

Before changing contributions or jobs

Ask the plan administrator for written answers when a statement is unclear.

• Formula: What contribution captures the full available employer match?
• True-up: Can uneven contributions miss a match without a year-end adjustment?
• Service date: When does the next vesting milestone occur?
• Forfeiture: What happens to unvested money after separation, rehire or a break in service?
• Fees and investments: Does the contribution level still fit the budget and available options?

Tax limits and plan terms change. Use current IRS guidance and your plan documents before adjusting payroll deferrals.

Use the guide for a documented decision
