Forfeiture Breakdown
How to Use This Tool
Follow these steps to calculate your forfeiture rate accurately:
- Enter your total vesting amount (the full value of the asset subject to vesting, e.g., 401(k) match, stock options).
- Input the full vesting period in years (e.g., 4 years for standard graded vesting).
- Add the number of years you were employed before leaving the plan or company.
- Select your vesting schedule: cliff (all at once after period), graded (equal annual portions), or custom (manual annual percentage).
- Choose forfeiture type: unvested only, or total (unvested plus early withdrawal penalties).
- Click Calculate Forfeiture to see your detailed breakdown, or Reset to clear all fields.
Formula and Logic
The calculator uses standard financial vesting and forfeiture rules to compute results:
- Vested Percentage: Determined by vesting schedule:
- Cliff: 0% if employed less than full vesting period, 100% if employed the full period.
- Graded: (Years Employed / Total Vesting Period) * 100%, capped at 100%.
- Custom: (Annual Vesting % * Years Employed), capped at 100%.
- Unvested Amount: Total Vesting Amount - (Total Vesting Amount * Vested Percentage).
- Forfeiture Rate: (Unvested Amount / Total Vesting Amount) * 100%.
- Total Forfeited: Unvested Amount + (Vested Amount * Early Withdrawal Penalty %) if total forfeiture type is selected.
All calculations are rounded to two decimal places for currency values.
Practical Notes
Keep these real-world finance considerations in mind when using this tool:
- Vesting rules are set by your employer or plan administrator: always verify actual vesting schedules in your plan documents, as custom schedules may vary.
- Early withdrawal penalties for retirement accounts (e.g., 401(k), IRA) are typically 10% if you withdraw before age 59.5, in addition to income tax.
- Forfeited amounts are permanently lost: unvested funds are retained by the employer or plan, not paid out when you leave.
- Stock option forfeiture may have tax implications: consult a tax professional to understand how forfeited options affect your taxable income.
- Partial years of employment: the calculator accepts decimal values for years employed (e.g., 2.5 years for 2 years and 6 months).

Frequently Asked Questions
What is a forfeiture rate?
A forfeiture rate is the percentage of vesting assets you lose when you leave a plan or company before meeting vesting requirements. It applies to employer-sponsored retirement matches, stock options, and other vesting benefits.
Does forfeiture apply to my own contributions?
No, forfeiture only applies to employer contributions or unvested equity awards. Your own contributions to retirement accounts or purchased stock options are always fully vested and owned by you.
Can I avoid forfeiture by staying employed longer?
Yes, most vesting schedules reward longer employment: staying through the full vesting period ensures you retain 100% of eligible benefits. Graded schedules vest portions annually, so even an extra year of employment reduces your forfeiture rate.
Additional Guidance
Use this tool as a starting point for more detailed financial planning:
- Cross-check results with your official plan documents to confirm vesting schedules and penalty rates.
- If you have multiple vesting assets (e.g., 401(k) and stock options), calculate each separately for accurate totals.
- Re-run calculations if your employment timeline changes (e.g., delayed departure date) to adjust your financial plan.
- Combine forfeiture projections with your overall budget and savings goals to avoid gaps in your financial plan.
