Quick Answer
For disposables, the calculator multiplies your expected product use by pack price and rounds up to whole packs. For reusable products, it estimates how many replacements you will need over time.
How to Calculate Period Products Cost
- Pick a product type.
- Enter the length of time you want to estimate.
- Fill in the period cycle and product use assumptions.
- Read the total cost and the average monthly cost.
Formula
Disposable cost = ceil(total items needed / units per pack) x pack price
Reusable cost = ceil(months / product lifetime in months) x purchase price
Worked Examples
Example 1: 12 months of pads at 4 units per day, 20 units per pack, and 8.99 per pack costs about 115.87.
Example 2: 12 months of tampons at 3 units per day, 16 units per pack, and 9.49 per pack costs about 124.37.
Example 3: A 24.99 menstrual cup lasting 24 months costs about 12.50 per year if replaced once every two years.
How to Interpret Your Results
| Monthly cost | Meaning | Action |
|---|---|---|
| Low | Under about 20 per month | Typical for reusable or lower-use setups |
| Moderate | About 20 to 50 per month | Common disposable spending range |
| High | Above about 50 per month | Check pack size, price, and usage assumptions |
