Why Use BizCalc Business Calculators?
Our profit margin calculator helps you understand gross and net margins from your revenue and expenses. The business loan calculator shows monthly payments, total interest, and amortization schedules. Use the break-even calculator to find exactly how many units you need to sell to cover your costs, or the business valuation calculator to estimate what your company is worth using industry-standard multiples.
Hiring is one of the biggest decisions a small business owner makes. Our payroll calculator estimates gross pay, tax withholdings, and net take-home pay. The employee cost calculator reveals the true total cost of hiring — including salary, benefits, and payroll taxes. Compare hiring options with our contractor vs employee calculator, or convert compensation with the salary to hourly calculator.
Self-employed? Our self-employment tax calculator estimates your Social Security and Medicare tax liability. Considering a business structure change? The LLC vs S-Corp calculator compares tax implications side-by-side so you can see potential savings from electing S-Corp status.
Set profitable prices with our markup calculator and understand the relationship between markup and margin. Freelancers can use the freelance rate calculator to determine an ideal hourly rate based on desired income, expenses, and billable hours. Track customer value over time with the customer lifetime value calculator, and monitor your startup's financial health with the burn rate and runway calculator.
