Creatine Loading Calculator
Calculate creatine loading and maintenance doses by body weight.
About Creatine Loading Calculator
Loading and maintenance-only protocols reach the same muscle saturation, differing only in how quickly. Splitting loading doses across the day reduces gastrointestinal discomfort. Because the end point is identical, loading is only worth doing when the timing matters, such as before a specific competition.
Formula
Creatine Loading
Loading is about 0.3 g per kg daily; maintenance about 0.03 g per kg daily
- loading
- A short high-dose phase that saturates muscle stores within days
- maintenance only
- Reaches the same saturation over roughly four weeks
Worked example
With the default values below, Creatine Loading Calculator returns Daily Loading Dose of 24.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- These figures are population-average estimates for training and recreational planning only and are not medical advice. Individual responses vary widely. Consult a qualified health professional before starting or significantly changing an exercise, supplement or nutrition programme, particularly if you have any medical condition. Creatine is among the most studied supplements but is not appropriate for everyone. Consult a healthcare professional before use, particularly if you have kidney disease or take other medication.

Frequently Asked Questions
How is Creatine Loading calculated?
Loading is about 0.3 g per kg daily; maintenance about 0.03 g per kg daily Loading and maintenance-only protocols reach the same muscle saturation, differing only in how quickly. Splitting loading doses across the day reduces gastrointestinal discomfort.
Why does Creatine Loading matter?
Because the end point is identical, loading is only worth doing when the timing matters, such as before a specific competition.
What values do I need to enter?
This calculator takes 4 inputs: Body weight, Protocol, Loading duration, Doses per day during loading. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
