The TDEE Calculator on GrabConvert does its one job with no ceremony: Total daily energy expenditure at every activity level. No account, no watermark, nothing kept — it runs, you download the result, and that is the whole transaction.
How to use the tdee calculator
- Enter your figures above — the result updates live as you type, and the defaults are sensible starting points.
- Everything is calculated right here in your browser: nothing you type is uploaded, stored or shared.
- Download the result where a download button is offered, or just copy the numbers you need.
Why people pick this over other converters
- No account, ever. Most big converter sites push sign-ups and paid tiers for basic jobs. Here the tool just works.
- No watermarks and no job counters on standard tools — fair-use rate limits keep things fast for everyone — and a generous 2 GB upload limit.
- Private by design: your file is processed in a temporary folder and deleted the moment your download finishes. Nothing is stored or shared.
- Fast: this page is a fraction of the size of the ad-heavy alternatives, and the same account-free toolbox has 529 other tools when you need them.
FAQ
Which activity level am I, really?
Most people overestimate by one level. Desk job plus three gym sessions is “light” to “moderate”, not “active” — that tier means a physical job or daily hard training. The table lets you sanity-check both readings.
Is this really free?
Yes — completely. A short ad before processing keeps every tool free; no account, subscription or credits are ever required.
What happens to my file?
It is processed in a temporary folder and deleted the moment your download finishes. We never store, view or share uploads.
Do I need to install anything?
No. Everything runs in your browser session against our servers — any phone, tablet or computer works.
