Lowest AFR - Why the Lowest Discount Rate Can Increase Deductions in CLT and RLE Models

Sep 15, 2026

Uploaded by Sarah

Modeling charitable life income gift plans relies on the IRS discount rate (AFR) to determine the charitable deduction, with higher rates generally producing higher deductions. However, the Charitable Lead Trust (CLT) and the Retained Life Estate (RLE) reverse the usual pattern: using the lowest available discount rate on the gift date increases the present value of charity’s interest and therefore the deduction. The document explains valuation logic, illustrates example deductions with two discount rates, and contrasts CLT/lead annuity versus lead unitrust effects.

Why do I choose the lowest Discount Rate when modeling a Charitable Lead Trust or a Retained Life Estate? Planned giving professionals typically choose the highest IRS Discount Rate when modeling charitable life income gift plans. Why? Because, the higher the Discount Rate, the higher the charitable deduction. Also known as the AFR or Applicable Federal Rate, the IRS Discount Rate is a factor in the calculation of the charitable deduction for many types of planned gifts. Think of the Discount Rate as the annual rate of return that the IRS assumes the gift assets will earn in the future. For example, a Discount Rate of 8% means the IRS thinks gift assets will earn an annual rate of return of 8% . Therefore, the higher the Discount Rate, the greater the value to which the IRS predicts the gift assets will grow, increasing the proportion of the gift that will goto charity. The greater the proportion of the gift that will go to charity, the greater the donor’s deduction. Two gift types do not follow this pattern. The Charitable Lead Trust (CLT) and the Retained Life Estate (RLE) both earn a larger deduction when you choose the lowest available Discount Rate on the date of the gift. Charitable Lead Trust: The CLT pays its income interest to charity, not to individuals, during the trust term. The lower the Discount Rate used to value the payments to charity, the greater their present value to charity. The deduction represents the present value of the lead trust payments to charity. Here is an example of a $1,000,000 charitable lead annuity trust that pays 5% or $50,000 per year for 20 years to charity. In the first example, we use the July 2001 Discount Rate of 6.2% . In the second example, we use the May 2001 Discount Rate of 5.8% . Deduction with a 6.2% Discount Rate Deduction with a 5. 8% Discount Rate $564,300 $582,920 Since the Discount Rate is the annual rate of return that the IRS assumes the gift assets will earn during the gift term, the higher the Discount Rate, the lower the value of money received by charity in the future. A change of 1% in the Discount Rate results in a difference of about 5% in the deduction for a lead annuity trust. The payout rate of a lead unitrust plays a far more important role than the IRS discount rate in the computation of the deduction. The Discount Rate has virtually no effect on the deduction for a lead unitrust since it only affects an adjustment factor, not the calculation of the value itself. Retained Life Estate: The deduction for a retained life estate in a residence or farm is the value of the charity's remainder interest at the time of the gift. For example, if the current discount rate is 6%, the IRS assumes that the donor will receive value equal to 6% of the property's worth from the use of the property each year during the course of the life estate.

FAQs

What is the AFR (Applicable Federal Rate) used for in planned giving models?

The AFR, also called the IRS discount rate, is a factor used to calculate the charitable deduction for many planned gifts by valuing the timing of future charity payments or interests.

Why do most professionals typically choose the highest IRS discount rate for modeling?

A higher discount rate generally yields a higher charitable deduction because it increases the predicted growth of gift assets and the portion expected to go to charity.

Why can choosing the lowest discount rate increase deductions for CLT and RLE?

For Charitable Lead Trusts and Retained Life Estates, the deduction increases when the lowest available discount rate is used on the gift date because it raises the present value of charity’s future interest.
