Calorie & TDEE
Calculator for Women
Calculate your Total Daily Energy Expenditure and basal metabolic rate. This free TDEE calculator uses the Mifflin-St Jeor equation calibrated for women.

How This Calorie & TDEE Works
This calculator uses the Mifflin-St Jeor equation, considered the most accurate for estimating Basal Metabolic Rate (BMR) - calories burned at rest. BMR is then multiplied by your activity level to find Total Daily Energy Expenditure (TDEE).
When Should You Use This Tool
Use this calculator when planning nutrition, weight management, or fitness goals. Your TDEE is a starting point - track actual results and adjust. Recalculate when your weight, age, or activity level changes significantly.
Is This Tool Accurate and Safe
Calorie calculations provide estimates. Individual metabolism varies based on muscle mass, hormones, genetics, and other factors. Use results as guidelines and adjust based on real-world results over 2-4 weeks. All calculations happen privately in your browser.
Frequently Asked Questions
What is the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is calories burned at complete rest - just to keep your body functioning. TDEE (Total Daily Energy Expenditure) adds calories from daily activities and exercise to BMR.
How accurate is the Mifflin-St Jeor equation for women?
Studies show it is the most accurate estimation method for most women, typically within 10% of actual metabolic rate. Individual variation exists based on muscle mass, hormones, and genetics.
How many calories should women eat to lose weight?
A deficit of 500 calories below TDEE typically results in about 0.5kg (1lb) loss per week. Larger deficits can slow metabolism and are harder to sustain. Never eat below BMR without medical supervision.
Does metabolism slow with age in women?
Yes, BMR decreases approximately 2% per decade after age 20. Menopause can further affect metabolism. Regular strength training helps maintain muscle mass and metabolic rate as you age.
