24 alternatives to Overpay mortgage or invest? I built a calculator to help you decide
Hey. I built a loan (mortgage) calculator that lets you compare the savings from overpaying your loan with the potential profits from investing those extra funds.

Both the overpayer and the investor have the same mortgage. 2. They both spend the same amount monthly. 3. The overpayer overpays the mortgage installments. 4. The investor puts that extra money into investments. Who comes out ahead after the…

Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically…

Hi HN, I built Own or Rent (https://ownorent.com) after getting frustrated with existing rent vs. buy calculators that hide assumptions and use confusing jargon.

As promised in another post a new version is out. This version focuses mainly on localization which is done by parsing the IP country before the page loads. Also, the users now have the possibility to select the language they see the page in. Previous post details: I built it because I needed a way to see how much will my early payments save in interest overtime. Most of the websites I found are solely made for the US, which does not help my case. So I built one that has a bit more flexibility in terms of loan data. Any feedback is appreciated.
