The Applicable Federal Rate (AFR) is a critical interest rate published monthly by the IRS. It plays a vital role in various tax and financial transactions, including loans, installment sales, and intra-family transfers. Using the correct AFR ensures compliance with tax laws and prevents unintended gift or interest income consequences.

What is the Applicable Federal Rate (AFR)?
AFR represents the minimum interest rates that must be charged on loans or financial agreements to avoid imputed interest under U.S. tax law. The IRS publishes three types of AFRs every month:
- Short-term AFR: For loans with terms of 3 years or less.
- Mid-term AFR: For loans with terms between 3 and 9 years.
- Long-term AFR: For loans exceeding 9 years.
Each AFR type may further be divided into annual, semi-annual, quarterly, and monthly compounding rates.
Why is the AFR Important?
- Tax Compliance: Ensures loans between family members or related parties meet IRS standards to avoid gift tax issues.
- Fair Interest: Prevents interest-free or below-market loans that may cause unintended taxable benefits.
- Estate and Gift Planning: Used in valuing loans and installment sales for estate and gift tax purposes.
- Loan Agreements: Sets a benchmark for legally enforceable interest rates.
How to Use the Applicable Federal Rate Calculator
- Select the AFR Type: Short-term, Mid-term, or Long-term, depending on loan duration.
- Choose Compounding Frequency: Annual, semi-annual, quarterly, or monthly.
- Enter Loan Principal: The amount of money loaned or involved in the transaction.
- Specify Loan Term: Length of the loan in years or months.
- Select AFR Month and Year: Use current or historical rates as needed.
- Calculate: The tool computes the interest payable or imputable over the loan period.
The Formula Behind AFR Interest Calculation
The general formula for compound interest using AFR is: A=P×(1+rn)ntA = P \times \left(1 + \frac{r}{n}\right)^{nt}A=P×(1+nr)nt
Where:
- AAA = amount after interest
- PPP = principal (initial loan amount)
- rrr = annual AFR rate (decimal form)
- nnn = number of compounding periods per year
- ttt = loan term in years
Interest earned or imputable is: Interest=A−P\text{Interest} = A – PInterest=A−P
Example Calculation
Suppose you have a $100,000 loan with a mid-term AFR of 1.5% annual rate compounded semi-annually for 5 years.
Given:
- P=100,000P = 100,000P=100,000
- r=0.015r = 0.015r=0.015
- n=2n = 2n=2 (semi-annual)
- t=5t = 5t=5 years
Calculate: A=100,000×(1+0.0152)2×5=100,000×(1.0075)10≈100,000×1.077≈107,700A = 100,000 \times \left(1 + \frac{0.015}{2}\right)^{2 \times 5} = 100,000 \times (1.0075)^{10} \approx 100,000 \times 1.077 \approx 107,700A=100,000×(1+20.015)2×5=100,000×(1.0075)10≈100,000×1.077≈107,700
Interest: 107,700−100,000=7,700107,700 – 100,000 = 7,700107,700−100,000=7,700
So, the interest payable over 5 years is approximately $7,700.
