Affiliate disclosure

Today, Viral Rang contains no affiliate links and earns no commissions. Every calculator, formula, and piece of guidance on the site is free of sponsored placement.

In the future, we may add product recommendations — for example, suggesting a paint brand or a tape measure alongside a calculator. If we do, two commitments hold:

• Clear labeling. Any link that could earn us a commission will be identified as such where it appears, in line with FTC guidelines — not buried in a footer.
• Editorial independence. Commissions will never change a formula, a default value, or a recommendation. The math is the product; nothing is for sale inside it.

When recommendations launch, this page will be updated to name the programs we participate in.
