Keep CalcOrchard free & useful
Every calculator on this site is free to use, has no sign-up, and runs entirely in your browser — nothing is sent to a server, nothing is stored. That's a promise, not a marketing line.
How this site is funded
Building and hosting CalcOrchard costs real money and time. To keep it free, we plan to use two revenue sources — both designed to stay out of your way:
- Unobtrusive display advertising once the site is approved for a publisher network. No pop-ups, no auto-play video, no interstitials.
- Relevant affiliate recommendations — if we mention a UK mortgage broker, an invoicing app, or a business book, and you buy through our link, we may earn a small commission at no extra cost to you. We only ever recommend things we'd genuinely suggest to a friend, and every affiliate link is clearly labelled.
Prefer to skip the ads?
If a calculator here saved you an hour of spreadsheet work — or, better, caught a mistake that would have cost you real money — the single most helpful thing you can do is share it:
- Send it to a friend or colleague who'd find it useful.
- Link to it from a blog post, Reddit answer, or forum reply where it fits.
- Bookmark it and come back next time instead of hunting for a new calculator.
Word-of-mouth is worth more to a small independent site than any donation. It's genuinely how we grow.
Feedback and requests
Found a bug? Want a calculator that doesn't exist yet? Have an idea for a better UX on one of the existing tools? Please get in touch. Every piece of user feedback improves the site — and it's the fastest way to get a calculator built for your specific need.
For businesses & publishers
If you run a UK accountancy practice, personal finance blog, or SaaS product and would like to embed a CalcOrchard calculator in your own site, that will be an option soon. Drop us a note and we'll add you to the early-access list — no charge for the first embedders.
Thank you for reading this far. Enjoy the tools. — The CalcOrchard team.
