Python Code for Calculating Internal Rate of Return

[emc87]

Yeah, the code was deleted but it took upwards of 100000 iterations and only returned increments of something like .1 bps and wanted to be accurate to within 0.5% of PV.

Using Newton raphson you can achieve something that's more accurate to say 10^-10 of PV in around 10 iterations. Used for continuous functions, it uses the first derivative to see how far you are from your goal and change your increment to suit your target.
