Found a bug, an outdated rate, or want to suggest a calculator? We genuinely want to hear it.
What to include
- Reporting a calculation issue? Tell us which tool, what you entered, what you got, and what you expected — we'll investigate and note any correction on the tool's page.
- Suggesting a new calculator? Describe the project decision you're trying to make ("how many pavers for a patio") — the best tools come straight from these requests.
- Advertising or partnership inquiries? Please note ads never influence our formulas or data, and we don't do paid placements inside calculators.
Note for you (delete before publishing): replace the email placeholder with a real address on your domain (hello@sumshed.com looks far more credible to visitors and AdSense reviewers than a Gmail). If you want a contact form instead of an email link, a static-site form service like Formspree or Web3Forms drops in with a few lines — say the word and I'll wire one up.
