How do you handle the accuracy of more complex financial calcs like amortization schedules with extra payments, and are the formulas reviewed by anyone with a finance background or just coded from standard references?
@cemreelibacebu The formulas themselves are standard textbook amortization math. To check the outputs, I use AI agents to run through a bunch of test cases and catch edge cases, and I've also hand-verified a few payments myself against manual calculations. Haven't had a finance pro formally review it yet, honestly — but happy to get that done if people think it'd help. Thanks for asking!
