Common Mistakes to Avoid
The most common mistake is not reviewing what you typed before hitting the button — one wrong character changes the whole result even though the tool itself worked correctly.
Sticking with default settings without checking what the other options do — the dropdowns and toggles usually exist because different situations genuinely need different settings.
Navigating away before saving the result — nothing is stored on our end by design (that is the privacy trade-off), so copy what you need before you leave the page.

There is nothing to learn here — if you can fill in a field and press a button, you already know how to use this. Bookmark it once and you are set for good.

❓ Frequently Asked Questions
What is BMR?
BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest just to stay alive — breathing, circulating blood, and cell production. It accounts for 60-70% of daily calorie burn.
How accurate is this calculator?
The Mifflin-St Jeor equation is considered the most accurate predictive formula, with margin of error around 10%. Individual metabolism varies, so treat results as strong starting points.
Should I eat below my BMR to lose weight?
Generally no. Eating below BMR for extended periods can slow metabolism. The calculator suggests a moderate 500-calorie deficit for sustainable weight loss of about 0.5kg per week.
