CalcKong financial calculators
Free, no-login financial calculators for Hong Kong
Hong Kong's tax rules, stamp duty bands, and mortgage stress tests change often β and most calculators online are either outdated, US-centric, or require you to sign up just to see a number. CalcKong fixes that with 17 free, HK-specific tools across 5 categories: π Property β π§Ύ Tax β π§ Retirement β π Investing β π Market data β
Hey Product Hunt π
I built CalcKong because every time I needed to check a Hong Kong mortgage stress test or stamp duty rate, I ended up on a bank site full of ads or a spreadsheet I had to rebuild from scratch.
It's a solo project β I handle the calculators, the data (HKMA/FRED feeds for rates), and the content myself. Everything is free and runs in your browser, no login needed.
Would love feedback on:
- Which calculator you'd add next
- Whether the mortgage stress test matches your bank's numbers
- Any HK-specific edge case I'm missing (e.g. non-permanent resident stamp duty)
Thanks for checking it out! π
Plugged in a property I was eyeing and the stamp duty breakdown matched what my agent quoted me, which already puts it ahead of most random calculators. Really nice to have something HK-specific without needing to create an account just to see a number.
love that you can actually see the number without hitting a paywall or signing up first, that alone is rarer than it should be. the category breakdown feels really thoughtful too, basically everything an HK person actually needs in one spot.
The stamp duty calculator actually matches what my accountant quoted me last year, which is more than I can say for the other HK tools I've tried. Finally something built for the city instead of awkwardly converted from US tax logic.
finally an hk tax calculator that actually uses the current bands and doesn't make me sign up for anything. the stamp duty section is super clear and the stress test number matched what my bank quoted me last month
It'd be really helpful if you could add a way to compare two property scenarios side by side, like different down payment amounts or stress test rates. Even just a simple toggle showing the monthly payment and total interest difference would save a ton of back and forth when I'm running numbers on flats in different price ranges.
Would love to see a "salary tax with MPF contribution" toggle in the tax calculator β most HK office workers deduct voluntary MPF contributions and it would save a manual step. Also adding a way to compare two scenarios side by side for the property stamp duty tool would be super handy for first-time vs upgrade buyer decisions.
