Use this capsule quantity calculator to estimate how many empty capsules you need for your powder, supplement, herb, or formulation.

This calculator is useful if you want to work out:
- how many capsules you can make from a certain amount of powder
- how many capsules are needed for a daily dose
- how many capsules are required for a batch
- how much powder each capsule should contain
Capsule quantity depends on your desired dose, powder density, capsule size, and how tightly the powder is packed.
Capsule Quantity Calculator Tool
Capsule Quantity Calculator
Work out how many empty capsules you need based on your total powder weight and powder per capsule.
Formula: Number of capsules = Total powder weight ÷ Powder per capsule
Formula Used
The basic formula is:
Number of capsules = Total powder weight ÷ Powder per capsule
Example:
If you have:
- Total powder: 100g
- Powder per capsule: 500mg
First convert 100g into mg:
100g = 100,000mg
Then:
100,000 ÷ 500 = 200 capsules
So you would need approximately:
200 empty capsules

Why Capsule Quantity Matters
Working out capsule quantity before filling helps you:
- avoid running out of empty capsules
- estimate production batches
- calculate supplement serving sizes
- reduce waste
- plan packaging quantities
- compare different capsule sizes
If you are filling capsules at home or preparing small batches, this calculator can help you choose the right pack size.
Example Capsule Quantity Chart
| Total Powder | Powder Per Capsule | Estimated Capsules Needed |
|---|---|---|
| 50g | 500mg | 100 capsules |
| 100g | 500mg | 200 capsules |
| 250g | 500mg | 500 capsules |
| 500g | 500mg | 1,000 capsules |
| 1kg | 500mg | 2,000 capsules |
Capsule Quantity by Capsule Size
Different capsule sizes hold different amounts of powder.
| Capsule Size | Approximate Capacity Range |
|---|---|
| 000 | 700–1400mg |
| 00 | 500–950mg |
| 0 | 300–700mg |
| 1 | 250–500mg |
| 2 | 180–370mg |
| 3 | 150–300mg |
| 4 | 100–210mg |
These are estimates only. Actual capacity depends on powder density and how tightly the powder is packed.

Example: How Many Capsules From 100g Powder?
If each capsule contains 500mg, then:
- 100g powder = 100,000mg
- 100,000mg ÷ 500mg = 200 capsules
So 100g of powder makes around 200 capsules at 500mg per capsule.
Example: How Many Capsules From 1kg Powder?
If each capsule contains 500mg, then:
- 1kg powder = 1,000g
- 1,000g = 1,000,000mg
- 1,000,000mg ÷ 500mg = 2,000 capsules
So 1kg of powder makes around 2,000 capsules at 500mg per capsule.
Choosing the Right Capsule Size
The number of capsules you need depends on how much powder each capsule can hold.
For example:
- a larger capsule may reduce the number of capsules needed
- a smaller capsule may be easier to swallow but requires more capsules
- low-density powders may need larger capsules
- dense powders may fit more easily into smaller capsules
For large doses, size 000, 00, or 0 may be suitable.
For smaller doses, size 1, 2, 3, or 4 may be more appropriate.
Capsule Quantity and Daily Dosage
You can also use this calculator to estimate how many capsules are needed per day.
Example:
If your daily dose is 1500mg and each capsule contains 500mg:
1500 ÷ 500 = 3 capsules per day
This means you would need:
- 21 capsules for 7 days
- 90 capsules for 30 days
- 180 capsules for 60 days
Things That Can Affect Capsule Quantity
Capsule quantity can vary depending on:
- powder density
- particle size
- moisture content
- tamping or compression
- capsule size
- filling method
- powder loss during filling
Always allow a small extra amount of capsules when filling manually.

Recommended Extra Capsules
When planning a batch, it is sensible to allow an extra 5–10% capsules.
This helps cover:
- spillage
- powder loss
- damaged capsules
- uneven filling
- test capsules
Example:
If you calculate that you need 200 capsules, ordering 220 capsules gives you a safer margin.

Frequently Asked Questions
How do I calculate how many capsules I need?
Divide your total powder weight by the amount of powder you want in each capsule. Make sure both values are in the same unit, usually milligrams.
How many capsules can I make from 100g of powder?
If each capsule contains 500mg, then 100g of powder makes around 200 capsules.
How many capsules can I make from 1kg of powder?
If each capsule contains 500mg, then 1kg of powder makes around 2,000 capsules.
Should I order extra empty capsules?
Yes. It is usually sensible to allow an extra 5–10% for spillage, damaged capsules, or uneven filling.
Does capsule size affect quantity?
Yes. Larger capsules hold more powder, so fewer capsules may be needed for the same total powder weight.
Why does my result differ when filling capsules?
Results may vary because powder density, compression, particle size, and filling method all affect how much powder fits inside each capsule.
