Calorie Deficit Calculator – Free Online Calculator

Last Updated : 24 Apr, 2024

Calorie Deficit Calculator: This tool is essential for anyone interested in weight loss and maintaining a healthy lifestyle. A calorie deficit occurs when you consume fewer calories than your body burns in a day. The GeeksforGeeks free online calorie deficit calculator helps you determine exactly how many calories you should eat each day to lose weight safely and sustainably. It considers your age, weight, height, gender, and activity level to give you a personalized calorie target.

How to Use Calorie Deficit Calculator

Calculating your calorie deficit is a three-step process:

1. Calculate Your Basal Metabolic Rate (BMR): This is the number of calories your body needs at rest to maintain basic bodily functions.

2. Factor in Physical Activity: Estimate how many calories you burn through daily activities and exercise, adding this to your BMR to get your maintenance calories.

3. Determine Your Calorie Deficit: Decide on a safe calorie deficit (typically between 500 to 1000 calories per day) to subtract from your maintenance calories.

Calorie Deficit Calculator Formula

A Calorie Deficit Calculator uses a special formula to help you figure out how many calories you should eat to lose weight.

The calorie deficit calculator formula:

Calorie Deficit = Maintenance Calories – Desired Calorie Intake

What is a Calorie Deficit Calculator?

A calorie deficit calculator isn’t a physical tool but a method to manually figure out how many calories you should be eating to lose weight. It guides you through the process of calculating your BMR and maintenance calories, then helps you subtract your desired calorie intake to find your deficit.

Calorie Deficit Calculator Table

Calorie Deficit	Weight Loss per Week (Approx.)
250	0.25 lbs
500	0.5 lbs
750	0.75 lbs
1000	1 lb
1250	1.25 lbs

Solved Examples on Calorie Deficit Calculator

1. A BMR of 1,400 calories and burning 600 calories through activity:

With a maintenance level of 2,000 calories, a deficit of 500 would mean eating 1,500 calories to lose about 1 lb per week.

2. A BMR of 1,600 calories and burning 400 calories through activity:

With a maintenance level of 2,000 calories, a deficit of 750 would mean eating 1,250 calories to lose about 0.75 lbs per week.

3. A BMR of 1,200 calories and burning 800 calories through activity:

With a maintenance level of 2,000 calories, a deficit of 1,000 would mean eating 1,000 calories to lose about 1 lb per week.

3 Practice Questions on Calorie Deficit Calculator:

1. If your BMR is 1,700 calories and you burn 300 calories through exercise, what calorie intake would create a 1 lb weekly weight loss?

2. How much weight can you expect to lose per week if you have a daily calorie deficit of 650?

3. What should your daily calorie intake be if your maintenance calories are 2,500 and you want to lose 1.5 lbs per week?
