I don't like that the loan calculator caps out at 50%, because the people most likely to want and need a simplified web interface are the ones most at risk of taking out batshit crazy loans (e.g. https://www.bigpictureloans.com/loan-rates).

For instance, check out this amortization table for one of those predatory lenders: https://www.calculator.net/amortization-calculator.html?cloa...

I'm capable of finding a working amortization calculator or banging it out on my HP-42s. You're capable of doing the math. The kind of people who can't do the math themselves are the ones who most need to see those numbers in front of their own eyes.
