BMR & TDEE Calculator: Quick and Accurate Estimates for Daily Calories
This post contains a ready to use BMR calculator that you can paste into Blogger's HTML editor. The tool calculates your Basal Metabolic Rate and offers an estimated Total Daily Energy Expenditure based on activity level. The calculator supports metric and imperial units and adjusts the labels automatically.

What is BMR?
BMR stands for Basal Metabolic Rate. It is the number of calories your body needs at rest to keep essential functions working: breathing, circulating blood, maintaining body temperature and supporting basic cellular activity. Knowing your BMR gives a baseline number you can use when planning calories for weight loss, gain or maintenance.
How to use this tool
Select metric or imperial units, enter your age, weight and height, then click Calculate. The tool shows your estimated BMR and an estimated Total Daily Energy Expenditure based on the activity level you choose. TDEE is BMR multiplied by an activity factor to reflect daily movement and exercise.
Accuracy and limitations
Calculators provide estimates not precise prescriptions. The Mifflin St Jeor formula works well for most adults but it cannot capture all individual differences. Factors such as muscle mass, hormonal status, medication and medical conditions change metabolic needs. If a reader has a special condition or needs personalized nutrition, recommend a registered dietitian or clinician.
Tips for bloggers
Place the calculator near a clear explanation and include one or two examples showing how to apply the numbers. For weight loss, a modest deficit from TDEE is safer than dramatic cuts. For muscle gain, a small surplus coupled with strength training is a common approach. Remind readers to track progress and adjust calories every few weeks.
