Creatine Maintenance Dose Calculator - Personalized for muscle and training habits

This creatine maintenance dose calculator is built for daily execution, not just theory. It starts with evidence-based bodyweight dosing, then adjusts for muscle category, diet pattern, and training frequency.

You also get scoop math, monthly supply planning, and a bridge phase when starting without loading. The goal is simple: take the right amount every day and keep your routine effortless.

Quick summary

The maintenance anchor is 0.03 g/kg/day. This calculator personalizes that number with muscle category, diet pattern, and training frequency, then adds practical outputs like scoops per day and monthly grams.

Creatine Maintenance Dose Calculator

Calculator

This maintenance-first creatine calculator gives a practical daily dose using body weight, muscle category, diet pattern, and training frequency. It also estimates scoops and monthly supply so planning is easy.

Body weight180.0 LB - 81.6 KG
Base maintenance (0.03 g/kg)2.4 g/day
Personalized maintenance target3.0 g/day
Maintenance range2.7-3.3 g/day
Scoops per day0.60 scoops/day
Scoops range0.54-0.66 scoops/day
Monthly supply estimate90 g / 30 days
300 g tub lasts100 days
500 g tub lasts167 days
14-day bridge (if starting unsaturated)Not needed

Dosing note: A single once-daily dose is usually practical for this target.

Status note: Stay consistent daily, including rest days, to maintain muscle creatine stores.

Baseline values below use 0.03 g/kg/day before personalized multipliers. Use the calculator for more individual dosing.

Body weightBaseline maintenanceTypical practical range
140 lb (63.5 kg)1.9 g/day3.0-3.5 g/day
170 lb (77.1 kg)2.3 g/day3.0-4.5 g/day
200 lb (90.7 kg)2.7 g/day3.0-5.5 g/day
230 lb (104.3 kg)3.1 g/day3.5-6.5 g/day

Formula

The core maintenance formula starts from bodyweight in kilograms, then applies small multipliers for real-life context.

Base maintenance (g/day) = weight (kg) x 0.03
Personalized maintenance = base x muscle multiplier x diet multiplier x training multiplier
Final maintenance clamp = 3.0 to 10.0 g/day
Bridge phase (if unsaturated) = weight (kg) x 0.05 for 14 days

This keeps outputs practical: high enough to be useful, low enough to stay easy to execute daily.

Example calculation

Example: 180 lb equals 81.6 kg. Base maintenance is 81.6 x 0.03 = about 2.4 g/day. If muscle category is Muscular (1.10x), diet is Mostly plant-based (1.05x), and training is 6-7 days (1.05x), personalized maintenance is about 2.9 g/day before practical clamping.

The calculator then sets a practical daily target and converts it into scoops and monthly grams so your supplementation stays consistent.

FAQ

What if my baseline maintenance is under 3 g/day?

A practical minimum often used is around 3 g/day for consistency and product scoop convenience.

Should I change my dose on rest days?

Usually no. Keep the same daily maintenance target to keep stores saturated over time.

When should I take my maintenance dose?

Timing matters less than consistency. Most people take it with a meal or post-workout.

Which creatine type is best for maintenance?

Creatine monohydrate remains the best-researched and most cost-effective form for most lifters.
