Made with care for accuracy. I'm not sure how you can claim this on the footer of every page when you're vibe coding these calculators.
This is more than just a bad side project - it's borderline malicious. How confident is the OP that every single one of these 60 calculators work all the time, with all edge cases? Because if someone is on your website using your calculator, they are putting trust in you. If it's wrong, it could have downstream impacts on them. I hope every single one has a comprehensive set of tests with good edge cases. But realist…
The compound interest calculator, which is their 'favorite page', already shows an incorrect value in the graph. So my faith in the other calculators isn't great. I also kinda doubt OP's story of them using that page all the time, since it took me about 20 seconds to find this issue.
