fin.interest-rate-swap-fixed-leg Calculator
Calculates the present value of the fixed leg of an interest rate swap from the fixed coupon, notional, and discount factors. Fixed leg PV plus floating leg PV must equal zero at initiation — the fixed rate is set to make this true.
Inputs
Notional Usd
Original borrowed or invested amount before interest. Interest accrues on the outstanding principal balance.
Fixed Rate Pct
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Tenor Yr
Reference formula or conversion factor shown for context.
Payment Freq Yr
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Discount Rate Pct
Rate used to bring future cash flows back to today's value. Higher rates make future money worth less — used in NPV, bond pricing, and valuation.
Results
PV of fixed leg ($)

number of payments
