We believe in full transparency about how CalcWonk works, how we make money, and how we handle your data.
Last updated: March 2026The short version: Some links on CalcWonk are affiliate links. If you click one and sign up for a product, we may earn a commission — at no extra cost to you. We only recommend products we genuinely think are useful.
CalcWonk participates in affiliate marketing programs, which means we may earn a commission when you click certain links and complete a purchase or sign-up. This is one of the primary ways we fund the development and maintenance of our free calculator tools.
When you see a recommendation for a product or service on CalcWonk — such as payroll software, accounting tools, or financial services — that link may be an affiliate link. If you click it and sign up, the company pays us a referral fee. You pay the same price you would have paid anyway; the commission comes from the company, not from you.
Affiliate relationships do not influence our calculator results, our editorial opinions, or the tools we choose to build. We recommend products based on their usefulness to our audience of small business owners and individuals making financial decisions. We do not accept payment to feature or promote specific products.
CalcWonk may have affiliate relationships with companies including, but not limited to:
Not every link on CalcWonk is an affiliate link. Links to government resources, educational content, and non-commercial tools are not affiliate links.
This disclosure is made in accordance with the Federal Trade Commission's guidelines on endorsements and testimonials (16 CFR Part 255). We are committed to transparency and believe you have a right to know when we have a financial relationship with a company we mention.
We're happy to answer any questions about how we work.
