Floating Rate Notes (FRNs)
Floating Rate Notes (FRNs) are relatively short-term investments that:
- mature in two years
- pay interest four times each year
- have an interest rate that may change or "float" over time
You can hold an FRN until it matures or sell it before it matures.

How we calculate the floating interest rate
The interest rate of an FRN is the sum of two components: an index rate and a spread.
- Index rate. This rate is tied to the highest accepted discount rate of the most recent 13-week Treasury bill. We auction the 13-week Treasury bill every week, so the index rate of an FRN is reset every week.
- Spread. The spread is a rate we apply to the index rate. The spread stays the same for the life of an FRN. The spread is determined at the auction when the FRN is first offered. The spread is the highest accepted discount margin in that auction.
The index rate plus the spread equals the interest rate.
We apply the interest rate to an FRN's par value every day. Thus, the FRN accumulates interest earned every day.
