10 = (n)
50 = (PV)
–30 =(PMT)
400 = (FV)

I=14.43587035% in end mode, and
I=10.20509732% in begin mode

That's close to the exact results (14,43587133% and 10,20509807%). I still wonder why an estimate > 100% leads to these results instead of the second, larger solutions.

I could do so if I was more familiar with V41. ;-)

Thank you very much. :-)
