When rate is used

ERISA 4022 Lump Sum Interest Rates




These interest rates are used to determine the lump sum equivalent of a participant's benefit when PBGC trustees a single-employer plan. If the value is less than $5,000, PBGC may pay that amount in one lump sum in lieu of a monthly annuity.  

Some ongoing pension plans use these rates to determine lump sum amounts, but the vast majority do not. Individuals seeking information about the interest rates their plans use to determine lump sums should contact their plan directly.

Immediate rate - 0.75%

Deferred rates (i1, i2, and i3) - 4.00%

Deferral periods (n1 and n2) - 7 and 8 years respectively


The ERISA 4022 Lump Sum Interest Rate Web page provides information about  how these rates are used, e.g., what i1, i2, i3, n1 and nrepresent, when to use the immediate rate, etc.

  • PBGC - Plans that terminate in December 2017
  • Ongoing plans that use ERISA 4022 rates to determine lump sums - depends on plan provisions

Variable-Rate Premiums


These rates, the spot segment rates, are used to determine the variable-rate premium (VRP) unless the plan has an election in effect to use the Alternative Premium Funding Target.

These rates are determined and published by the IRS.


  • 1st segment rate - 2.05% 
  • 2nd segment rate - 3.61% 
  • 3rd segment rate - 4.27%

These are the October 2017 spot segment rates.  They are used by plans with plan years beginning in November 2017 for determining either the 2017 or 2018 VRP, depending on whether the plan uses the "lookback rule". 

The VRP interest rate web page provides additional information about applicability.

Late Premium Payments


PBGC charges interest on late PBGC premiums using the IRC section 6601(a) rate (i.e., what IRS charges for late tax payments).

Late payment penalties may also apply.  See Late Payment Charges for more information.

The same rates are also used to compute certain interest charges applicable when PBGC trustees a plan (e.g., interest on required contributions unpaid as of the termination date).
