| Party | Pays | Receives | Benefits When |
|---|---|---|---|
| Fixed-rate payer | Fixed rate (e.g., 4%) | Floating rate (e.g., SOFR) | Rates rise (receives more floating) |
| Floating-rate payer | Floating rate (SOFR) | Fixed rate (4%) | Rates fall (pays less floating) |
Formula
Net Payment = (Fixed Rate − Floating Rate) × Notional × Day Fraction
Key point
Swaps are how companies manage interest rate risk. A company with floating-rate debt can enter a swap to pay fixed — effectively converting their floating-rate loan into a fixed-rate loan without refinancing.
Try it
Check current SOFR rates in the **Macro** section. If a company locked in a 3.5% fixed rate when SOFR was 3%, and SOFR is now 5%, they’re saving 1.5% on their notional annually.
Check-in
A company with $500M in floating-rate debt enters a swap paying 4% fixed and receiving SOFR (currently 5.3%). What’s the net annual benefit?

Interest rate swap: a company pays fixed 4%, receives floating (SOFR) on $100M notional for 5 years. Current SOFR: 5.5%. What's their net monthly cash flow?
