Three kinds of useful
Start with a free tool. When you need the whole job done, there's a template or a kit for it.
Free tools
Calculators that run in your browser. No sign-up, and nothing you type is saved or sent.
Templates
Ready-made spreadsheets you copy into your own account. Pay once, keep them.
Kits and guides
Step-by-step kits and printable guides for the jobs a tool alone can't do.
Made for the work you do
Each trade gets its own shelf: the free tools first, then the templates that do the whole job.

Who should we make for next?
We're choosing the next trade now. Run a small business and stuck on a fiddly calculation or a messy spreadsheet? Tell us at hello@popkiln.com.
Know what every bake really costs.
Most home bakers price from ingredients alone. The Bakery Recipe Costing sheet adds your time, overheads and packaging, so the price you set covers the real cost.

One-off payment through Gumroad. Google Sheets only. 30-day refund if it doesn't work as described.
How we make things
One job, done properly
Each product solves one problem from start to finish, rather than a bundle of half-finished tabs.
Numbers you can trust
Formulas are checked by automated tests against an independent model before anything is released.
Yours to keep
Pay once, no subscription. Templates live in your own account, and your data stays with you.
New tools, now and then
Get an email when we add a calculator, a template or a new trade. No more than a couple a month, and you can unsubscribe from any email.
Sign-up runs on our store page, powered by Gumroad.
Fresh out of the kiln
Popkiln is a small independent studio making digital products for people who make and sell: calculators, spreadsheets and kits that each do one job well. We start with one trade at a time and build its shelf properly before moving on.
A kiln is where raw clay comes out finished and ready to use. That's the idea behind everything here: small things, made properly, that you can put to work the same day.
Pricing tips and charts
We share practical guides, like margin versus markup and cake serving charts, on Pinterest.
