How to Use an Interest Rate Swap Calculator: Manually, Using BlueGamma, and Using Bloomberg

Introduction

Calculating interest rate swaps is essential in financial modelling. This guide will show you how to calculate interest rate swaps manually, using BlueGamma's Interest Rate Swap Calculator, and via Bloomberg.

How to Calculate Interest Rate Swaps Manually

1. Understand the Swap Structure: Interest rate swaps involve exchanging a fixed interest rate for a floating rate.
2. Gather Necessary Data: Collect the notional amount, fixed and floating rates, payment frequency, and swap duration.
3. Calculate Payments:
   • Fixed Payment: Multiply the notional amount by the fixed interest rate and payment period.
   • Floating Payment: Multiply the notional amount by the floating rate and payment period. Update for each period based on market rates.
4. Discount Factors and Forward Rates: Manually estimating discount factors and forward rates is complex and time-consuming. For accurate calculations, use live data such as EURIBOR forecasts.
5. Compare Payments: Determine the net swap payments by comparing fixed and floating payments.
