MortgageMeasure is a free calculator that answers the classic question: should you pay off your mortgage early or invest that money instead? Get a full PITI breakdown, model extra payments, compare investing vs paying down your loan, and see live mortgage rates from the St. Louis Fed — all in one place. No sign-up, no ads, no data collected.


Hey Product Hunt! 👋
I built MortgageMeasure after getting frustrated that every mortgage calculator just shows you a monthly payment — but none of them help you answer the real question: what should I actually do with extra money?
The invest vs pay down comparison is the feature I'm most proud of. You plug in your numbers and it tells you exactly which option wins — and by how much.
A few things I'd love feedback on:
Is the PITI breakdown clear enough for first-time buyers?
What features are missing that you'd want to see?
Does the invest vs pay down verdict feel trustworthy?
Happy to answer any questions about how the math works. And if you find any edge cases where the numbers look off — please let me know! 🙏
