Weekly Calorie Target Calculator: Plan Your Burn

Setting a weekly calorie burn target helps you structure your exercise routine for weight loss, maintenance, or performance. Instead of guessing how many calories you need to burn each day, a weekly target accounts for daily fluctuations in activity, rest days, and varying workout intensities. This guide explains how to calculate your weekly calorie burn goal using MET values, your basal metabolic rate (BMR), and activity tracking.

Why a Weekly Target?

Daily calorie targets can be rigid and discouraging. A missed workout or a higher-calorie day can feel like a failure. A weekly target smooths out these variations. For example, if your goal is to create a 3,500-calorie deficit per week (equivalent to one pound of fat loss), you can spread that across seven days: 500 calories per day, or combine a few higher-burn days with lighter days. This flexibility makes adherence easier.

According to the Compendium of Physical Activities, the energy cost of activities is expressed in METs (Metabolic Equivalents). One MET is the energy you burn at rest. Knowing the MET value of your activities allows you to calculate actual calorie burn. For a deeper understanding, see our complete guide to calorie burn and MET values.

Calculating Your Weekly Calorie Burn Target

Step 1: Determine Your Basal Metabolic Rate (BMR)

Your BMR is the calories your body burns at rest to maintain vital functions. The Mifflin-St Jeor equation is widely used:

• Men: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (y) + 5
• Women: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (y) – 161

For example, a 30-year-old woman weighing 70 kg and 165 cm tall: BMR = 10×70 + 6.25×165 – 5×30 – 161 = 700 + 1031.25 – 150 – 161 = 1420.25 calories/day.

Step 2: Estimate Your Total Daily Energy Expenditure (TDEE)

Multiply your BMR by an activity factor:

• Sedentary (little exercise): BMR × 1.2
• Lightly active (1-3 days/week): BMR × 1.375
• Moderately active (3-5 days/week): BMR × 1.55
• Very active (6-7 days/week): BMR × 1.725
• Extra active (physical job + exercise): BMR × 1.9

For the example woman with light activity: TDEE = 1420 × 1.375 ≈ 1953 calories/day.

Step 3: Set Your Weekly Calorie Deficit or Surplus

To lose 0.5 kg (1 lb) per week, create a deficit of 3,500 calories. To maintain, eat at TDEE. To gain muscle, add 250-500 calories per day. Your weekly burn target from exercise is the difference between your TDEE and your calorie intake goal, minus the deficit you want from diet.

For example, if your TDEE is 1953 and you want a 500-calorie daily deficit, you need to burn 500 calories through exercise and diet combined. If you reduce diet by 250 calories, you need to burn 250 calories through exercise daily, or 1,750 per week.

Using MET Values to Plan Workouts

MET values let you calculate calories burned per minute: Calories/min = MET × weight (kg) × 0.0175. For a 70 kg person:

• Walking at 3 mph (MET 3.5): 3.5 × 70 × 0.0175 ≈ 4.3 cal/min
• Running at 6 mph (MET 9.8): 9.8 × 70 × 0.0175 ≈ 12.0 cal/min
• Cycling at moderate effort (MET 8.0): 8.0 × 70 × 0.0175 ≈ 9.8 cal/min
• Swimming freestyle (MET 8.3): 8.3 × 70 × 0.0175 ≈ 10.2 cal/min

Our running calorie calculator and cycling calorie calculator use these MET values to give precise estimates.

Sample Weekly Plan for a 70 kg Person

Goal: Lose 0.5 kg per week with a 500-calorie daily deficit. Daily burn target from exercise: 300 calories (the rest from diet). Weekly total: 2,100 calories from exercise.

Total: 1,993 calories (close to 2,100). Adjust durations based on your weight and exact MET values. For more on HIIT, see our HIIT calorie calculator.

Adjusting for Accuracy

Calorie burn estimates are approximations. Factors like terrain, age, fitness level, and efficiency affect actual burn. For walking, walking uphill increases MET. For running, running vs jogging changes MET. For cycling, indoor vs outdoor can differ. Use our calorie burn calculator tool for personalized estimates.

Common Mistakes

• Overestimating MET: Using “moderate” effort when you’re actually light. Be honest.
• Ignoring NEAT: Non-exercise activity thermogenesis (walking to work, fidgeting) adds up. Track steps with a pedometer.
• Not adjusting for weight loss: As you lose weight, your BMR and calorie burn decrease. Recalculate every 5 kg.

Tools and Apps

Popular apps like MyFitnessPal, Cronometer, and Fitbit allow you to set weekly calorie goals. Many sync with heart rate monitors for better accuracy. Our 10,000 steps calculator shows how walking contributes.
