Many employers with Defined Benefit Plans provide an option for a retiree to take a lump sum instead of a monthly pension. With interest rates rising quickly, the calculations used to value a lump sum will likely change dramatically and may offer a significant timing opportunity.
Lump Sum Math: Lump sums are computed with a mathematical calculation very similar to the math used in mortgage loans. The Lump Sum is the present value of the monthly pensions. It’s based on three ingredients:
· The monthly pension
· The rate of interest used to compute the lump sum, and
· The life expectancy of the individual
The Benefit. The monthly pension is simple: the bigger the monthly pension, the bigger the lump sum, all things being equal.
Life Expectancy. The life expectancy, or mortality, of the individual, also has an effect. Two employees with identical monthly benefits will have different lump sums based on their age. For example, suppose Tom and Susan both work at a company for 30 years and have monthly pensions of $3,200. Tom is 62, Susan is 66. According to IRS Mortality Table for 2022, Tom will live about 23.08 years and Susan about 19.68 years. Note the IRS mortality table is a little bit of a math lift; you have to actually build a life expectancy table. Drop me an e-mail if you’d like an explanation of how to do it.
Interest Rate: Threat and Opportunity. Because of the mathematics, interest rates have a major effect on a lump sum calculation, particularly considering the rising rate environment. The mathematics of lump sums are a present value calculation, meaning the lump sum is the present value of a stream of payments at an interest rate for a period of time. Think of a mortgage – a mortgage loan is the present value of the payments. A $3,000 monthly mortgage payment on a 3%, 30-year mortgage would sustain a mortgage loan of $711,518. If the rate was 5%, the amount of a mortgage loan would be $558,845. If these were pension lump sums, the higher interest rate causes the lump sum to decrease substantially (by over 21%).
The method the IRS uses to compute interest on lump sums affects the outcome as well – there is a blended rate for the first five years of payments, years 6-20, and payments 20 years or later. Using the IRS Minimum Present Value Segment Rates for May 2022, the first segment is 3.23%, the second segment is 4.59% and the third segment is 4.69%. With those rates, Tom would have a blended rate of about 4.502%, and Susan a rate of 4.69%, however, it’s the interest rate calculation that has the biggest impact.
The rates used by the IRS in the Minimum Present Value Segment are divided in three segments: the first segment is for the first five years (of the participant’s life expectancy) of the calculation, the second segment is for years six through twenty, and the third segment for years after twenty. Using the IRS computed mortality for a 66-year-old, the life expectancy is 19.68 years, which would utilize only the first and second segments. The life expectancy of a 62-year-old is 23.08 years, which would use all the segments. A blended rate can be used to approximate the valuation of a lump sum.
