FAQ
What if all cash flows are same sign?
IRR is undefined. You need at least one negative and one positive cash flow.
How is multiple-solution risk detected?
The calculator warns when cash-flow signs change two or more times.
What if results differ from spreadsheets?
Check day count basis, date parsing, sign convention, and initial guess.
