About ConvertCrunch

ConvertCrunch is a growing collection of 576+ free online tools built for freelancers, small business owners, and anyone who needs to crunch numbers or convert files quickly.

The site currently spans 24 major categories, including payroll, tax, AI economics, ecommerce margins, developer utilities, and investment planning.

Our Mission

ConvertCrunch exists to make professional-grade financial tools accessible to everyone. Tax calculators, payroll estimators, and investment planners should not be locked behind expensive software or require an accounting degree to use. We build every tool with the goal of giving individuals and small businesses the same quality of calculation that large enterprises rely on — completely free, with no account required.

Our Methodology

Accuracy is the foundation of every tool we publish. Our methodology is built on three principles:

• Primary sources: Calculations are built from primary sources — government tax agencies, official rate tables, and published formulas.
• Cross-verification: Every calculator is cross-checked against known outputs before publishing.
• Ongoing maintenance: Tools are updated when rates, brackets, or rules change (with source and date noted).

How We Build Tools

Each tool goes through a structured development process before it reaches you:

1. Research: We start with official sources — the IRS, HMRC, ATO, CRA, and other government agencies — to gather current rates, thresholds, and regulatory details.
2. Development: Tools are built browser-first and privacy-preserving. All calculations run locally in your browser so your financial data is never transmitted to a server.
3. Verification: Before publishing, every calculator is cross-checked against official government calculators, published examples, and known reference outputs to ensure accuracy.
4. Maintenance: We perform regular updates when tax years change, rates are adjusted, or regulations are amended. Each update references the official source and date of change.

Trust and Transparency

• Your data stays on your device: All tools run in your browser — your data never leaves your device. We do not collect, store, or transmit the numbers you enter into any calculator.
• Sources cited on every page: We cite our sources directly on tool pages so you can verify the rates, formulas, and rules we use.
• Published editorial standards: Our full review and correction process is documented in our Editorial Policy.

Our Promise

• Always free: no paywalls, no premium tiers, and no usage limits.
• Privacy-first: conversions are designed for browser-first execution with no account required.
• No signup: use any tool immediately.
