Description
Searching for "paycheck calculator" or "JSON formatter" usually lands on a site cluttered with ads and pop-ups, or one that asks you to sign up before showing a result. Tools Berry is a straightforward alternative: about 90 free calculators and utilities — from US state paycheck calculators to mortgage and loan tools to image and text converters — that process everything in your own browser, so your financial figures or files never get uploaded to a server.
Tools Berry is built and maintained independently by Edmond Daher, a software engineer, and organized into four families: money/tax tools (paycheck calculators for all 50 US states, mortgage, loan, inflation, savings), everyday calculators (dates, units, cooking, fitness, grades), developer/text/image utilities (diff checker, QR codes, JSON formatting, image conversion), and document tools. Tax and financial figures are drawn from IRS and Social Security Administration releases and state department-of-revenue data, with Daher stating he personally verifies figures against primary sources and maintains a public corrections log. The site is entirely free with no paid tier.
💬 Our review
The short version: for a quick, ad-light calculator that doesn't ask for your email or upload your numbers, Tools Berry does the job well — just don't expect the depth or polish of a dedicated tax-prep service for anything complex.
Against Calculator.net, the closest direct comparison, Tools Berry's differentiators are the explicit client-side-only privacy promise and a public corrections log for tax figures, which is unusual transparency for a free calculator site. Against TurboTax or Bankrate for the tax-specific tools, Tools Berry is obviously not a substitute — it explicitly states the founder isn't a CPA or tax advisor and the site isn't tax/legal/financial advice, so it's best for quick estimates, not filing. Being a one-person project (Edmond Daher, no team, no company) is honest but also the main risk: sustainability and update cadence for 50-state tax tables rest on a single individual rather than a funded team. For fast, private, free calculations, it's genuinely useful; for anything where getting the number wrong has real financial consequences, verify with a professional tool or advisor.
