Recovery Carbohydrate Target Calculator
Estimate hourly recovery carbohydrate from body weight and the entered grams-per-kilogram-per-hour rate, then multiply that hourly amount by the priority recovery window. Compare the resulting gram target with the current recovery plan, round the target into whole recovery portions, and flag whether the next demanding session is strictly less than 24 hours away.

How to use Recovery Carbohydrate Target Calculator
- Enter body weight in kilograms and the recovery rate in grams per kilogram per hour; their product is the hourly recovery target.
- Set the priority recovery window in hours and multiply it by the hourly target to obtain the full-window carbohydrate target.
- Enter the current recovery plan and carbohydrate per recovery portion, then review the nonnegative plan gap and whole portions rounded upward.
- Enter the hours until the next demanding session; the short-turnaround flag is one only below 24 hours and is zero at 24 hours or later.
- Use the recovery clock to stage the calculated portions, while treating its two-hour display as an illustration rather than a change to the entered priority window.
Calculator guide
Understanding Recovery Carbohydrate Target Calculator
Recovery carbohydrate planning is a body-weight rate carried across a defined priority window, not a generic activity adjustment. This page keeps the hourly target, full-window target, current plan, portion count, and short-turnaround flag tied to the production model.
Calculation method
How the calculation works
Calculate the entered gram-per-kilogram-per-hour recovery target across the priority window, then compare it with the current plan and practical portion size. Let W be body weight in kg, r the recovery rate in g/kg/hour, H the priority recovery window in hours, C the current recovery plan in g, P the portion size in g, and N the hours until the next demanding session. Hourly target T_hour = W x r. Window target T_window = T_hour x H. Plan gap G = max(0, T_window - C). Whole portions Q = ceil(T_window / P). Urgency U = 1 when N < 24 hours; otherwise U = 0. With production defaults W = 72 kg, r = 1.0 g/kg/hour, H = 4 hours, C = 240 g, P = 60 g, and N = 18 hours: T_hour = 72 g/hour, T_window = 288 g, G = 48 g, Q = 5, and U = 1. Reverse check: five 60 g portions provide 300 g of capacity, so the fifth portion can be 48 g and the displayed portions still reconcile to the 288 g target.
Recovery window
Stage the full-window target without changing its basis
The production target is accumulated across the entered priority recovery hours. The clock then illustrates how whole practical portions can be staged after exercise; its 120-minute axis does not replace the entered window or alter the arithmetic.
Worked situations
Practical examples
- At the production defaults, 72 kg times 1.0 g/kg/hour gives 72 g/hour; across four hours the target is 288 g, leaving a 48 g gap from a 240 g current plan and requiring five 60 g portions.
- If the same 288 g target is compared with a 320 g current plan, the plan gap is zero rather than negative, while coverage can exceed 100%.
- A next-session value of 23.9 hours produces the short-turnaround flag, while exactly 24 hours does not; the boundary is strict rather than inclusive.
Better inputs
Useful tips
- Coordinate carbohydrate with fluid, sodium, protein, and the next planned session.
- Use food labels and measured portions when the recovery target matters.
- Recalculate when body weight, selected recovery rate, priority window, portion size, or next-session timing changes.
Before relying on the result
Limitations and common mistakes
- The page does not estimate glycogen depletion or prescribe a clinical diet.
- The selected rate and priority window must come from the actual training context; the model does not infer them from session duration or intensity.
- The short-turnaround flag only compares the entered next-session interval with 24 hours and does not establish whether rapid recovery is medically or practically required.
Reference
Key terms
- Hourly recovery target
- Body weight multiplied by the entered recovery rate, expressed in grams per hour.
- Priority recovery window
- Entered number of hours over which the hourly target is accumulated.
- Window target
- Hourly recovery target multiplied by priority recovery hours, expressed in grams.
- Plan gap
- The window target minus current planned carbohydrate, floored at zero.
- Whole recovery portions
- Window target divided by portion size and rounded upward.
- Short-turnaround flag
- A value of one when the next demanding session is under 24 hours away, otherwise zero.

Frequently asked questions
Is the priority recovery window fixed at two hours?
No. The target uses the entered priority recovery hours. The two-hour clock is only an execution illustration.
Does this include protein?
No. This calculator isolates carbohydrate.
What happens when the current plan is higher than the target?
The plan gap is floored at zero; coverage may exceed 100%, but no negative gap is reported.
Why is the portion count rounded up?
A fractional final requirement still needs enough food or product capacity, although the last consumed portion can be smaller.
Does exactly 24 hours count as a short turnaround?
No. The production flag is active only when the entered interval is strictly below 24 hours.
