Embed a CalcKit Calculator on Your Website

Give your visitors a working calculator without building one. Copy the code under any calculator below, paste it into your page's HTML, and the calculator appears — fully working, no sign-up, no setup.

Embedding is free — just keep the small “Powered by CalcKit” link under the calculator. That link is the only condition, and it must stay visible.

Used by / attribution

Any website may use these embeds, free, with no sign-up. The only condition is attribution: every embed must keep the “Powered by CalcKit” link under the calculator, linking back to https://calckit4u.com. Do not hide, remove, or alter that link.

How it works

1. Copy the code for the calculator you want. 2. Paste it into your page's HTML where the calculator should appear. 3. Done — the calculator loads from calckit4u.com and always stays up to date. The small “Powered by CalcKit” link under it must stay visible.
