About Small Business Calc
Helping small business owners make smarter financial and operational decisions through simple, free, and practical business tools.
Our Mission
Running a small business means making pricing and money decisions constantly, often without the time, budget, or background to get them exactly right. We built this site because the same few questions come up again and again for owners, freelancers, and contractors:
- Pricing services correctly
- Understanding profit margins
- Managing payroll expenses
- Evaluating hiring decisions
- Planning revenue growth
- Improving profitability
Small Business Calc exists to take the guesswork out of those questions. Every calculator on this site is built to turn a messy, manual calculation into a clear answer in under a minute, so you can make better decisions and spend less time wrestling with formulas.

Calculation Methodology & Standards
Accuracy and transparency are essential when making business decisions. All formulas and calculation logic across Small Business Calc are designed following established US small business financial practices:
- Standard Accounting Formulas: Margin, markup, break-even, and profit estimators adhere to universally recognized GAAP (Generally Accepted Accounting Principles) fundamentals.
- Official Regulatory References: Payroll, contractor, and tax-related calculation structures draw upon frameworks defined by the Internal Revenue Service (IRS), Small Business Administration (SBA), and US Department of Labor.
- Independent Verification: Logic and calculations are routinely tested against real-world sample scenarios to ensure mathematical accuracy before publication.
