TDEE Plus builds free calculators for calories, metabolism and macros. Most calculators give you one number and no explanation. Ours show every formula, compare the main equations side by side, and give you macros for each goal, so you can see where the number comes from and decide what to do with it.
What makes these calculators different
- Three formulas, compared. Mifflin-St Jeor, Revised Harris-Benedict and Katch-McArdle run on the same inputs.
- Macros for every goal. Cutting, maintaining and bulking each get their own grams, not one split for all.
- Private by design. Calculations run in your browser. We don't collect your weight, height or any other input.
- Sources on every page. Claims about formulas, protein and weight change link to the research behind them.
Who is behind TDEE Plus
Adnan is the founder of TDEE Plus. He is based in Pakistan and has spent about three years in search engine optimisation, studying what people search for and what they find. One pattern kept showing up: most calorie calculators hand you a single number with no explanation, no comparison and no sources.
TDEE Plus is his answer to that. He builds the calculators, writes the guides from published research, and tests every calculator against hand-worked examples before it goes live. The aim is simple: a tool you can trust because you can see exactly how it works.
Adnan is not a dietitian or doctor, and the site doesn't pretend otherwise. That is why every formula is shown, every claim is sourced, and health content is being arranged for review by a registered dietitian.
How we work
- Show the working. If a calculator uses a formula, the formula is on the page.
- Cite the evidence. Guides list the studies and official sources they rely on.
- Put safety first. Low calorie targets are flagged, and the calculators are limited to adults.
- Respect privacy. Your inputs stay in your browser.
- Keep it free. Every calculator is free to use, with no sign-up.
Medical review
We are arranging review of our health content by a registered dietitian. Until that review is complete, no page on this site is labelled as medically reviewed. Once it is, each reviewed page will name the reviewer, their credentials and the review date.
