Boldin vs ProjectionLab showing much different Monte Carlo results
39M, married (38), with 2 kids (2 and 4). Have started playing around with retirement software and seeing if it would be feasible for my wife and I to retire early around 50-55. I know the Monte Carlo calculators and software are only as good as the inputs that you feed in, but I am currently getting fairly different results in the calculators when trying to set up a similar plan between Boldin and ProjectionLab. Boldin gives my current plan a 75% success rate whereas ProjectionLab gives it a 93% success rate.
Is this difference common? Is it because I'm still about 10-15 years out and the numbers will line up better as I approach my goal retirement? I know the default rates can be adjusted, but I currently have the rate of inflation at 3% on each, with the rate of investment returns kept at the software defaults (Boldin actually has a higher default rate of return than PL, so odd that the Monte Carlo is lower in Boldin).
