Hong Kong's tax rules, stamp duty bands, and mortgage stress tests change often โ and most calculators online are either outdated, US-centric, or require you to sign up just to see a number.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: ๐ Property โ ๐งพ Tax โ ๐ง Retirement โ ๐ Investing โ ๐ Market data โ
Hey Product Hunt ๐
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 โ 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! ๐

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

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.
