Steps to Use the Calculator

1. Enter the bottle size (ml).
   Most Fairy Liquid bottles range between 433ml, 520ml, and 780ml, but enter the exact size you have.
2. Enter your average usage per wash (ml).
   For example, a conservative user might use 3ml per wash, while a heavy user may use 7–10ml.
3. Enter the number of washes per day.
   For instance, a family washing after each meal may wash 3 times a day, while a single person may wash only once.
4. Click "Calculate Duration."
   The tool will then show you:
   • The total number of washes you’ll get from the bottle.
   • How many days will the bottle last?
   • The approximate number of weeks before you need a replacement.
