QDRO Calculator: Divide a Pension in Divorce
A pension earned during a marriage is typically marital property. A Qualified Domestic Relations Order divides it between spouses. Model the coverture fraction, a fixed percentage split, or a fixed dollar amount and see the present value each party receives.
How this calculator works and the math behind itHow QDRO division works
Dividing a defined benefit pension in divorce requires deciding what share of the pension the non-employee spouse (the alternate payee) receives, and how to measure it. The two most common approaches are the coverture fraction method and a fixed percentage or dollar split.
The coverture fraction method divides the marital share first, then splits that share. If the participant was in the plan for 30 years total and married for 20 of them, the marital portion is 20/30 = 67%. The alternate payee typically receives 50% of the marital share -- 50% of 67% = 33.3% of the total pension. The participant keeps their pre-marital service and any post-divorce service entirely.
The fixed percentage method is simpler: the alternate payee gets a flat percentage of whatever the participant eventually receives. This method shares in the upside of future salary growth and additional service, which can be advantageous for the alternate payee in a long-career situation. The risk: the ultimate benefit depends on when the participant retires and what they earn -- variables outside the alternate payee's control.
A fixed dollar QDRO is rare for defined benefit plans but common for 401(k)s. For DC plans, the split is straightforward: $X goes to the alternate payee's account immediately. The alternate payee can then roll it into their own IRA without taxes or penalties, regardless of their age, under the QDRO exemption.
This calculator provides estimates to help you understand the magnitude of what's being divided. The actual QDRO document must be drafted by a qualified attorney, reviewed by the plan administrator for acceptability, and entered as a court order. Plans have specific language requirements, and a QDRO rejected by the plan administrator is worthless. Never finalize a divorce settlement involving a pension without a qualified QDRO attorney reviewing the order.
Frequently asked questions
What is a QDRO?
A Qualified Domestic Relations Order is a court order that divides a retirement plan in a divorce. It must meet specific requirements under ERISA and IRC § 414(p) before the plan administrator will honor it. Without a valid QDRO, the plan cannot legally pay benefits to anyone other than the original participant.
What is the coverture fraction?
Marital service years divided by total plan service years. If you worked 28 years in the plan and were married for 20 of them, the coverture fraction is 20/28 = 71.4%. The alternate payee typically receives 50% of that fraction: 35.7% of your total pension. You retain 100% of the pre-marital and post-divorce service accruals.
Are QDRO distributions subject to the 10% early withdrawal penalty?
No. IRC § 72(t)(2)(C) explicitly exempts distributions made to an alternate payee under a QDRO from the 10% penalty -- regardless of the alternate payee's age. The alternate payee still owes ordinary income tax on any distributions not rolled over to an IRA. A direct rollover to a traditional IRA avoids all taxes until withdrawal.
What happens to survivor benefits in a QDRO?
A QDRO can designate the alternate payee as the survivor annuity beneficiary, giving them continued payments after the participant's death. This is a critical detail that must be explicitly addressed in the QDRO. Without survivor benefit language, the alternate payee's income stops when the participant dies. Many attorneys default to preserving the alternate payee's survivor benefit rights.
Do federal pensions use QDROs?
No. FERS and CSRS use a Court Order Acceptable for Processing (COAP) through OPM. Military pensions use the Uniformed Services Former Spouses' Protection Act (USFSPA). TSP accounts use a Retirement Benefits Court Order (RBCO). Each has different language requirements and is administered by a different agency. A QDRO drafted for a private employer plan will be rejected by OPM or DFAS.
