I built a mortgage payment calculator for people who just want clean, fast numbers without the lead-gen friction. https://toolvault.co/tools/mortgage-payment-calculator It started because every time I tried to run mortgage scenarios, I hit one of these problems: Forms that demand email/phone before showing results Slow, ad-heavy pages that feel like landing funnels, not tools Calculators that only show principal + interest, ignoring real monthly costs What this tool does: Calculates full monthly housing cost: principal, interest, property tax, insurance, PMI, and HOA…

    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. It will help you answer a key question: is it smarter to overpay your mortgage or invest the extra money? See the hard data and make smarter financial choices! The comparison is simple: 1. 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…

    Hi everyone, I’ve been on Hacker News for a good number of years, but this is my first “Show HN”. I changed jobs recently. Tax is weird in Europe (and maybe other places as well?) in that different amounts go out at different times and repeat at various intervals. I needed to make sure I had enough cashflow to make all upcoming payments, I didn't want any surprises. So I created a little tool for my own purposes, then had fun putting a small HTML frontend on it as I thought it might be useful for someone else. I'm a backend developer in my day job, as you can probably tell from the design :)…

    Hi HN, I am a solopreneur in the evenings and a software engineer during the day. In the past, I have created lots of calculators for my web projects and freelancing friends. These were pretty basic, but users always welcomed them. I also used currently available builders, but the problem was that they were either slow, broke on mobile devices, had nonsense page view limits, or were expensive. Some even ticked all those boxes. So I have decided to create my own, with a simple interface, and called it Creative Widgets (if it ever takes off, I plan to add more exciting stuff like charts, etc,…
