Hi everyone,

Recently, a friend of mine who lives in New Jersey complained about the lack of accurate paycheck calculators online—every site seems to give different numbers. As a software engineer based in Australia, I saw this as a great opportunity to learn some new web development techniques.

So, I built NJ Paycheck Calculator. The website is now nearly finished. Since it's almost ready to launch, it would be a waste if nobody uses it :)

Here's what makes this calculator stand out:

• Up to date: It uses the latest tax rates.

• Secure: No data is shared because all calculations happen in your browser.

• Mobile friendly: It works great on any device.

Feel free to give it a try, and any feedback is greatly appreciated. I really want to make this website great. Thank you!

Updates:

18/6/2024

• Added input for hourly pay.

• Implemented state tax withholding using NJ-W4 instead of marginal tax brackets.

• Fixed SUI calculation: the rate is now 0.425% with a wage base of $42,300.

TODO:

• Add inputs for 401(k) contributions and insurance. (Research needed on the tax impact.)

• Implement step 2b from the W-4 form.
