How to model this...?

Need some help here on how to model the breakeven for a swap to floating. Ie - how much libor would need to raise to make the trade present value neutral… have some calcs already done but just curious if anyone has any experience doing this before… Thanks

if tradeValue = x current fxrate =r find dif such that x/(1+r + dif) = floatvalue you can do it by hit and trial manually, much easier if you use iterations in any coding laguage

You can use Solver in excel or make a circular reference and choose the “Iterations” option
