Weight Gain Calculator – Free Online Calculator

Last Updated : 22 Apr, 2024

Weight Gain Calculator: A weight gain calculator helps you figure out how much weight you need to gain to reach a healthy size. It uses some information about your body, like your height and current weight, to give you a goal weight. Weight gain means getting heavier. The weight gain calculator is a free online tool that helps you to calculate the amount of weight you have to gain. The website GeeksforGeeks offers a simple and fast tool for this conversion, ensuring accurate results every time. This calculator is versatile and can be used by anyone for various purposes, including in engineering.

How does Weight Gain Calculator Works

The weight gain calculator helps us figure out how much weight we might gain based on our calorie intake and activity levels. It works like this:

1. Input Information: First, we need to tell the calculator about ourselves. This includes our age, gender, height, current weight, goal weight, activity level, and how quickly we want to gain weight.

2. Calculations: The calculator uses this information along with some formulas to estimate how many calories we need each day to reach our weight gain goal.

3. Calorie Intake: Once we know our daily calorie needs, we can plan our meals to make sure we eat enough calories each day.

4. Monitoring Progress: Over time, we can use the calculator to see if we’re gaining weight at the expected rate. If not, we might need to adjust our calorie intake or activity levels.

By following the calculator’s guidance and making adjustments as needed, we can work towards our weight gain goals in a healthy and controlled way.

Weight Gain Calculator Formula

By understanding and using weight gain calculator formulas, you can tailor your diet and exercise plans to reach your weight gain goals safely and effectively.

1. Calculate Basal Metabolic Rate (BMR): This is how many calories your body needs to function at rest. The formula for BMR varies based on factors like age, sex, weight, and height.

One common formula is the Harris-Benedict equation:

For men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)

For women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)

2. Calculate Total Daily Energy Expenditure (TDEE): This includes your BMR multiplied by an activity factor based on your daily activity level (sedentary, lightly active, moderately active, very active).

3. Determine Caloric Surplus: To gain weight, you need to consume more calories than your body burns. A caloric surplus is usually around 250-500 calories per day for gradual weight gain.

4. Calculate Weight Gain Rate: Based on a pound of body weight being roughly equivalent to 3500 calories, you can estimate weight gain over time. For example, a 500-calorie surplus daily could lead to about a pound of weight gain per week.

Weight Gain Calculator Table

Here’s a simple weight gain calculator table to help you understand how weight gain can be calculated:

Factors	Calculation
Basal Metabolic Rate	Estimate your BMR using your age, gender, weight, and height. There are many online calculators available for this.
Total Daily Energy Expenditure (TDEE)	Multiply your BMR by an activity factor that represents your typical level of activity throughout the day. This will give you an estimate of the total calories you burn in a day.
Caloric Surplus	Determine how many extra calories you need to consume to gain weight. This is usually done by adding a certain amount of calories (usually between 250 to 500 calories) to your TDEE.
Macronutrient Ratio	Decide on the ratio of carbohydrates, proteins, and fats you want to consume. A common ratio for weight gain is 40% carbohydrates, 30% proteins, and 30% fats.
Daily Caloric Intake	Calculate the total number of calories you need to consume each day by adding the caloric surplus to your TDEE. This will give you a target for your daily caloric intake.
Tracking Progress	Keep track of your weight regularly to see if you’re gaining weight at the desired rate. Adjust your caloric intake and macronutrient ratio as needed to achieve your weight gain goals.

By following these steps and regularly monitoring your progress, you can effectively use a weight gain calculator to help you reach your desired weight. Remember to consult with a healthcare professional or a nutritionist before making any significant changes to your diet or exercise routine.

Solved Examples on Weight Gain Calculator

Example 1:

Initial Weight: 150 lbs
Target Weight: 170 lbs
Time Frame: 3 months (or 90 days)

Formula: Weight Gain = (Target Weight – Initial Weight) / Time Frame

Calculation: Weight Gain = (170 lbs – 150 lbs) / 90 days = 20 lbs / 90 days ≈ 0.22 lbs per day

Example 2:

Initial Weight: 65 kg
Target Weight: 75 kg
Time Frame: 6 months (or 180 days)

Formula: Weight Gain = (Target Weight – Initial Weight) / Time Frame

Calculation: Weight Gain = (75 kg – 65 kg) / 180 days = 10 kg / 180 days ≈ 0.056 kg per day

Example 3:

Initial Weight: 70 stones
Target Weight: 80 stones
Time Frame: 1 year (or 365 days)

Formula: Weight Gain = (Target Weight – Initial Weight) / Time Frame

Calculation: Weight Gain = (80 stones – 70 stones) / 365 days = 10 stones / 365 days ≈ 0.027 stones per day
