Retirement
Employer match and vesting: Definition, Formula and Example
An employer match is a plan contribution tied to employee contributions; vesting determines how much of an employer-provided benefit the employee owns.
Scope: U.S. employer retirement plans; plan documents and current tax-year limits control.
Other names and related labels: Matching contributions; Vested retirement benefits.
How it works
A plan may match a fraction of employee deferrals up to a compensation percentage or use several tiers. Employees own their own salary deferrals; employer contributions can follow a vesting schedule. Limits, eligible compensation, timing and any true-up depend on the plan and applicable rules.
Simple one-tier match = matching percentage × min(employee contribution, eligible compensation × matched band)
This formula precedes applicable plan and legal caps. A vested employer amount also depends on the plan’s vesting percentage.
A 50% match on the first 6% of $60,000 pay
Assume the employee contributes 10% of eligible annual pay.
- Employee contribution: $60,000 × 10% = $6,000.
- Matched band: $60,000 × 6% = $3,600; employer match: $3,600 × 50% = $1,800.
- If the match is 40% vested, $1,800 × 40% = $720 of that match is vested.
The match is $1,800; in the hypothetical vesting case, $720 of the match is owned.
One annual calculation; no cap binds. The 40% vesting rate is illustrative, not a universal schedule.
The worked example uses the assumptions above. Related tools may model a different scope; check their descriptions before comparing results.
A 50% match does not mean 50% of your salary
It normally applies to eligible contributions within a defined band. The 401(k) projection assumes full vesting; it does not calculate forfeitures or every payroll-specific matching rule.
