About Tools Berry
Tools Berry is a collection of over a hundred free calculators and converters that run entirely in your browser. There is no signup, no download, and nothing gets uploaded to a server. You open a page, enter your numbers, and get results immediately. The focus is on money and tax tools, but the site also covers everyday utilities, image converters, and developer helpers.
The tax and paycheck calculators are the centerpiece. Every US state has a dedicated paycheck calculator that applies federal and state withholding rules for 2025 and 2026 tax years. You enter salary, filing status, and deductions, and the tool breaks down gross pay, federal tax, state tax, Social Security, Medicare, and net take home. There are also standalone calculators for mortgage payments, loan amortization, retirement projections, and savings growth. If you need to figure out what a refinance would save you or how much you should set aside monthly, the tools handle that without requiring an account or submitting personal data anywhere.
Everyday calculators cover percentages, tips, cooking conversions, time tracking, and fitness metrics like BMI and calorie estimates. These are simple utilities, but having them in one place with a consistent interface is convenient when you just need a quick answer. The image tools let you resize, compress, convert formats, and create PDFs from images without leaving the browser. Developer utilities include JSON formatters, Base64 encoders, and text analysis helpers.
All processing happens client side. The site is explicit that nothing is uploaded, which matters when you are entering salary figures or other financial details. The trade off is that you need a reasonably modern browser to run the JavaScript, but that covers nearly everyone at this point.
The person behind the site is Edmond Daher, a software engineer who emphasizes that he is not a CPA or tax advisor. The tax figures are traced to primary sources like IRS releases and state tax schedules, and the site maintains a corrections log for any errors. If you find a mistake, you can email hello@tools-berry.com and expect a response within days. This level of transparency is uncommon for free calculator sites, and it helps build trust when the stakes involve money.
There is no paid tier. Everything is free, supported by ads or personal motivation rather than subscriptions. The audience is anyone who needs a quick calculation and prefers not to install software or create an account just to figure out their take home pay or how much interest a loan will cost.

Two months in, no regrets
Have been running Tools Berry for a while, here is where I land. Got real value out of completely free with no signup required. Would sign up again without thinking twice.
Pulled its weight from week one
Tools Berry has quietly become part of my daily flow. Their take on completely free with no signup required is genuinely good. It fits well for calculating take home pay for a new job offer.
Solid but not perfect
Found Tools Berry on a Show HN thread and I am glad I clicked. Where it really wins is client side processing with no data uploads. It just works, day after day, without surprises. One thing that bugs me is ad supported, so you will see ads on pages. Would sign up again without thinking twice.
Worth a look
Three months of Tools Berry later, here is what holds up. Where it really wins is mortgage and loan calculators. Setup was painless and I was productive the same day. It fits well for estimating mortgage payments before applying. It earns its place in my stack.

It just works
Found Tools Berry on a Show HN thread and I am glad I clicked. It has shaved real time off my week. It does what it says, which is rarer than it should be. No regrets so far.
Solid but not perfect
Tried Tools Berry on a side project first, then rolled it out everywhere. Where it really wins is mortgage and loan calculators. Found it works best for estimating mortgage payments before applying. One thing that bugs me is ad supported, so you will see ads on pages. Hard to imagine going back to my old setup.
Pulled its weight from week one
