Forfeiture Rate Calculator

Calculation Results
💡 Employee contributions are always 100% vested immediately. Forfeiture only applies to unvested employer contributions.
How to Use This Tool
Follow these steps to calculate your potential forfeiture rate:
- Enter your total employee contributions to the retirement or investment account. These are always 100% vested, so they are not subject to forfeiture.
- Enter the total employer contributions (matching, profit sharing, etc.) to the account. Forfeiture only applies to unvested portions of these contributions.
- Select your plan’s vesting schedule type: Cliff Vesting (all employer contributions vest at once after a set period) or Graded Vesting (a percentage vests each year).
- Enter your total years of service with the employer or years the account has been open.
- If using Cliff Vesting, enter the cliff period (e.g., 3 years, 5 years). If using Graded Vesting, enter the percentage that vests per year (e.g., 20% per year).
- Click "Calculate Forfeiture" to see your vesting percentage, forfeiture rate, and dollar amounts for forfeited and vested balances.
- Use the "Reset" button to clear all inputs and start over, or "Copy Results" to save your calculation.
Formula and Logic
This calculator uses standard IRS and private sector vesting rules for retirement accounts:
- Employee contributions are always 100% vested immediately, so they are excluded from forfeiture calculations.
- For Cliff Vesting: If years of service are greater than or equal to the cliff period, vesting percentage is 100%. Otherwise, vesting percentage is 0%.
- For Graded Vesting: Vesting percentage = (Years of Service × Vesting Rate per Year), capped at 100%.
- Forfeiture Rate = 100% – Vesting Percentage
- Forfeited Amount = Total Employer Contributions × (Forfeiture Rate / 100)
- Total Vested Balance = Employee Contributions + (Total Employer Contributions × (Vesting Percentage / 100))
- Total Unvested Balance = Total Employer Contributions – (Total Employer Contributions × (Vesting Percentage / 100))
Practical Notes
Keep these finance-specific tips in mind when using this calculator:
- Most 401(k) plans require employer contributions to vest within 3-6 years under IRS rules. Cliff vesting can not exceed 3 years for most tax-qualified plans, while graded vesting can not take more than 6 years to reach 100%.
- Early withdrawal penalties (10% for those under 59.5) are separate from forfeiture. Forfeiture applies only to unvested employer contributions when you leave the employer, not when you withdraw from the account.
- If you have multiple employer contributions with different vesting schedules, calculate each separately and sum the results.
- Some plans have "partial cliff" vesting, where a portion vests early. Use the graded vesting option for these plans by entering the average annual vesting rate.
- Forfeited employer contributions are typically reallocated to remaining plan participants, not returned to the employer.
Why This Tool Is Useful
This calculator helps you make informed financial decisions:
- Plan job changes: Know exactly how much employer contributions you will forfeit if you leave before vesting.
- Budget for withdrawals: Avoid unexpected losses by understanding your vested balance before making early withdrawals.
- Compare job offers: Evaluate the value of employer retirement matches by factoring in vesting schedules.
- Financial planning: Accurately project your retirement savings by excluding forfeited unvested contributions.
Frequently Asked Questions
Does forfeiture apply to my own employee contributions?
No. By law, employee elective deferrals to 401(k), 403(b), and similar plans are always 100% vested immediately. Forfeiture only applies to employer-provided contributions like matching funds or profit sharing.
What happens to forfeited employer contributions?
Forfeited contributions are not returned to the employer. Under IRS rules, they must be reallocated to other participants in the retirement plan, used to pay plan administrative fees, or held in a suspense account for future allocation.
Can my employer change the vesting schedule after I start contributing?
Employers can change vesting schedules for future contributions, but they cannot retroactively reduce the vesting rate for contributions already made. Check your plan documents for details on schedule changes.
