Add a free TDEE calculator to your site

If you write about fitness or run a gym, you can put our calculator on your own page. It's free, there's no sign-up, and it has no ads.

Copy this code

Paste it into your page's HTML wherever you want the calculator. On WordPress, use a "Custom HTML" block. On Squarespace or Wix, use an "Embed" or "Code" block.

<iframe id="tdeecalc" src="https://tdeecalculator.ai/embed/" title="TDEE calculator" loading="lazy" style="width:100%;max-width:560px;height:900px;border:0;display:block;margin:0 auto"></iframe>
<p style="text-align:center;font-size:13px">TDEE calculator by <a href="https://tdeecalculator.ai/">TDEECalculator.AI</a></p>
<script>window.addEventListener("message",function(e){if(e.origin==="https://tdeecalculator.ai"&&e.data&&e.data.tdeecalcHeight){document.getElementById("tdeecalc").style.height=e.data.tdeecalcHeight+"px"}});</script>

The small script lets the calculator grow and shrink to fit, so your readers never scroll inside a box. If your site doesn't allow scripts, leave that line out and the calculator still works at a fixed height.

Options

  • Dark mode: change the address to https://tdeecalculator.ai/embed/?theme=dark, or ?theme=auto to follow each reader's phone or computer setting.
  • Width: it fits any column from phone size up. Change max-width:560px if you want it wider.

What your readers get

  • Their TDEE and BMR from the Mifflin-St Jeor equation, or Katch-McArdle if they add their body fat.
  • A calorie target to lose, maintain or gain, with the pace rated against their body weight and a safe minimum.
  • Daily protein, carbs and fat in grams.

We don't show ads, email sign-ups or shopping links inside the calculator. Nothing your readers type is sent to us; the math runs in their browser. We count how many times the calculator is opened, the same way we count visits to our own site.

A few simple rules

  • Keep the "TDEE calculator by TDEECalculator.AI" line under it.
  • Don't change the calculator or put it inside a page that claims it's your own tool.
  • It gives estimates for healthy adults aged 18 to 80. Please don't present it as medical advice.
