CostOak

Business finance, in real numbers

Rates, fees and the true cost of money for freelancers and small businesses. General information, never personal financial or tax advice.

First guides in progress

Finance guides follow stricter sourcing rules (IRS, SBA and lender disclosures) and take longer to check.

  • Self-employment tax explained
  • Quarterly estimated taxes
  • Business line of credit costs
  • Merchant cash advance: the real price

Every page will carry a price range, what moves it, where the numbers came from and the date they were checked. See how we price.
