A creatine dosage calculator helps you determine the right amount of creatine monohydrate to take based on your body weight. Creatine is the most researched sports supplement in history, proven to increase strength, power output, and lean muscle mass. Getting your dose right ensures you saturate your muscles effectively without wasting product or money.
Your Details
Loading phase saturates muscles in 5-7 days, then switches to maintenance.
Loading Phase (Days 1-7)
Take --g four times per day, spaced evenly (e.g., breakfast, lunch, afternoon, dinner). After 5-7 days, switch to the maintenance dose.
Maintenance Phase (Day 8 Onward)
Take your maintenance dose once daily. Consistency matters more than timing.
Timing & Absorption Tips
Take with carbs and protein for better absorption. A post-workout shake with creatine is ideal.
Post-workout is slightly preferred over pre-workout, but consistency matters more than timing.
On rest days, take it at any time with a meal. The goal is to maintain saturated creatine stores.
Creatine monohydrate is the most studied and cost-effective form. Fancy variants offer no proven advantage.
Hydration Reminder
Creatine draws water into your muscles, so it is important to stay well hydrated. Drink an extra 16-32 oz (0.5-1 liter) of water per day on top of your normal intake when supplementing with creatine. Dehydration can reduce performance and cause cramping.

Safety & Research
Most studied supplement: Over 500 studies confirm creatine monohydrate is safe and effective for healthy adults.
Kidney function: No adverse effects on kidney function in healthy individuals at recommended doses.
No cycling needed: There is no scientific reason to cycle on and off creatine.
Consult a doctor if you have pre-existing kidney disease or are taking medications that affect kidney function.

How to Use the Creatine Dosage Calculator
Creatine monohydrate is the most researched and proven sports supplement available. It increases phosphocreatine stores in your muscles, allowing you to produce more ATP energy during high-intensity exercise. This translates to more reps, heavier lifts, and faster recovery. This free creatine dosage calculator gives you a personalized dosing plan based on your body weight so you can supplement effectively without guesswork.
Step 1: Enter Your Body Weight
Type your current body weight into the input field. Use the toggle switch to choose between pounds and kilograms. Your body weight is the primary factor in determining your optimal creatine dose because the standard recommendations from sports science research are expressed as grams per kilogram of body weight. The calculator converts automatically regardless of which unit you enter.
Step 2: Choose Your Protocol
Select between two supplementation approaches. The Loading + Maintenance protocol involves taking a higher dose (0.3 grams per kilogram per day) for five to seven days to rapidly saturate your muscle creatine stores, then switching to a lower maintenance dose. The Maintenance Only protocol skips the loading phase entirely and uses the daily maintenance dose from the start. This approach takes three to four weeks to fully saturate your muscles but avoids the higher initial intake. Both protocols reach the same saturation level, so the difference is simply how quickly you get there.
Step 3: Review Your Dosage Plan
After clicking Calculate, you will see your personalised dosage plan. If you chose the loading protocol, the calculator shows your daily loading dose split into four even doses throughout the day, along with the total grams needed for the seven-day loading phase. The maintenance section shows your ongoing daily dose and monthly consumption. Use the cost calculator below the results to estimate how much your supplementation will cost by entering your product price and container details.
Step 4: Estimate Your Cost
Enter the price of your creatine container, the number of servings per container, and grams per serving to see your cost per day and per month. Creatine monohydrate is one of the most affordable supplements available, typically costing just a few cents per day. Compare different products to find the best value. The creatine calculator shows exactly how many days a single container will last at your personalised maintenance dose.
Maximizing Your Results
Take creatine with a meal containing carbohydrates and protein to improve uptake. Stay well hydrated by drinking an additional 16 to 32 ounces of water daily. Consistency is the most important factor. Take your maintenance dose every day, including rest days, to keep your muscle creatine stores saturated. There is no need to cycle on and off creatine. Stick with creatine monohydrate powder, which is the most studied, most effective, and most affordable form available.
FAQ
Is this creatine calculator free to use?
Yes, the Creatine Dosage Calculator is completely free with no limits. You can recalculate as many times as you like with different body weights and preferences. No signup or account is needed and everything runs locally in your browser.
Is my personal data safe and private?
Yes, all calculations happen entirely in your browser using client-side JavaScript. Your weight and other inputs are never sent to a server, stored in a database, or shared with anyone. When you close the page your data is gone.
How much creatine should I take per day?
The standard maintenance dose is about 3 to 5 grams of creatine monohydrate per day for most adults. A more precise calculation is 0.03 grams per kilogram of body weight. This calculator gives you a personalized dose based on your exact body weight.
Do I need a creatine loading phase?
A loading phase is not required but it saturates your muscles faster. Loading involves taking 0.3 grams per kilogram of body weight per day for 5 to 7 days, split into 4 doses. Without loading, you can take the maintenance dose daily and reach full saturation in about 3 to 4 weeks.
Is creatine safe to take every day?
Yes, creatine monohydrate is one of the most extensively studied supplements in sports nutrition. Research consistently shows it is safe for healthy adults when taken at recommended doses. The International Society of Sports Nutrition considers it safe for both short-term and long-term use.
When is the best time to take creatine?
Research suggests taking creatine post-workout with a meal containing carbohydrates and protein may improve absorption slightly. However, the most important factor is consistency. Taking it at the same time every day matters more than the specific timing.
Does creatine cause water retention or bloating?
Creatine draws water into muscle cells, which can cause a small increase in body weight of 1 to 3 pounds, mostly from intracellular water. This is not the same as bloating or subcutaneous water retention. The effect is generally considered beneficial for muscle performance and appearance.
Should I cycle creatine or take it continuously?
There is no scientific evidence that cycling creatine provides any benefit. Research supports continuous daily supplementation at the maintenance dose. Your body does not build a tolerance to creatine, so taking breaks is unnecessary for healthy adults.
