Enter Gender, Age and Height ft in — height Feet and the remaining scenario settings to review daily surplus with this tool. The surplus is extra energy relative to the entered maintenance assumption.
Daily calorie target = Estimated maintenance calories + Selected calorie surplusThe calculation links Gender, Age and Height ft in — height Feet to daily surplus. The surplus is extra energy relative to the entered maintenance assumption. It does not identify how much of an eventual weight change would be muscle, fat or water.
Enter Gender, Age and Height ft in — height Feet and the remaining scenario settings to review daily surplus with this tool. The surplus is extra energy relative to the entered maintenance assumption.
Explore the arithmetic difference between modeled maintenance energy and a higher intake. Use it to compare surplus sizes without assuming a fixed rate of tissue gain.
The surplus is extra energy relative to the entered maintenance assumption. It does not identify how much of an eventual weight change would be muscle, fat or water.
Prepare Gender, Age, Height ft in — height Feet, Height ft in, Current weight, Target weight, Activity level and Weight gain rate. Confirm the baseline expenditure and add only the intended surplus rather than entering the full intake as an additional amount.
The surplus is extra energy relative to the entered maintenance assumption. It does not identify how much of an eventual weight change would be muscle, fat or water. Maintenance estimates and actual intake can be uncertain. A constant calorie-to-weight relationship cannot guarantee a gain rate or individual nutritional suitability.
Use the full settings in the worked-example table. They produce Daily Surplus: 500. Compare the method and units as well as the displayed number.
The displayed relationship is Daily calorie target = Estimated maintenance calories + Selected calorie surplus Confirm the baseline expenditure and add only the intended surplus rather than entering the full intake as an additional amount.
Maintenance estimates and actual intake can be uncertain. A constant calorie-to-weight relationship cannot guarantee a gain rate or individual nutritional suitability. For personal care, discuss the measurements and method with a qualified clinician.
Worked calorie surplus calculator example. Set Gender = Male; Age = 25; Height ft in — height Feet = 5; Height ft in = 9; Current weight = 140; Target weight = 160; Activity level = Lightly Active (1-3 days/week); Weight gain rate = Moderate (1 lb/week). The corresponding output is Daily Surplus: 500. The surplus is extra energy relative to the entered maintenance assumption.

| Field | Example value | Entry check |
|---|---|---|
| Gender | Male | Use the option required by the selected estimation model. |
| Age | 25 | Use the stated unit and the measurement required by this model. |
| Height ft in — height Feet | 5 | Keep feet and any inch remainder in their separate fields. |
| Height ft in | 9 | Keep feet and any inch remainder in their separate fields. |
| Current weight | 140 | Use the measurement unit printed beside this field and a consistent measuring technique. |
| Target weight | 160 | Use the measurement unit printed beside this field and a consistent measuring technique. |
| Activity level | Lightly Active (1-3 days/week) | Select the description that matches the scenario being estimated. |
| Weight gain rate | Moderate (1 lb/week) | Enter a percentage in the form requested by the field, keeping its stated time basis. |
Relationship used for this example: Daily calorie target = Estimated maintenance calories + Selected calorie surplus
The surplus is extra energy relative to the entered maintenance assumption. It does not identify how much of an eventual weight change would be muscle, fat or water.
| Output | Displayed result |
|---|---|
| Daily Surplus | 500 |
With these settings, daily surplus is 500. Use the same units and calculation mode when reproducing this example.
The surplus is extra energy relative to the entered maintenance assumption. It does not identify how much of an eventual weight change would be muscle, fat or water. Maintenance estimates and actual intake can be uncertain. A constant calorie-to-weight relationship cannot guarantee a gain rate or individual nutritional suitability.
Replace the illustrative gender value (Male) with your own value, then complete the other inputs for the same scenario. Confirm the baseline expenditure and add only the intended surplus rather than entering the full intake as an additional amount.
