Twelve ratios, grouped into liquidity, debt, profitability and efficiency, tell you most of what a lender or buyer would want to know about a small business. Each takes two numbers from your balance sheet or income statement.
GuideBreak-even ROAS: how to find the ad return you need to stop losing money
Your break-even ROAS is the return on ad spend at which ads pay for themselves and nothing more. It comes from your margin after every cost except ads, so two stores with the same ROAS can have very different profits.

GuideEtsy fees explained: what Etsy charges on every sale in 2026
Etsy takes a listing fee, a 6.5% transaction fee and a payment processing fee on most sales, plus Offsite Ads and a regulatory operating fee in some cases. Here is what each one costs, what it is charged on, and how much a typical order loses to fees.
GuideHow much does an employee cost? The real cost beyond salary
An employee costs more than their salary. In the US you also pay employer payroll taxes, unemployment taxes, insurance and any benefits you offer, which often adds 20% to 40% or more on top of pay depending on the benefits.
