How the 30-Day Refill Calculator Works

The 30-Day Refill Calculator is designed to give instant results based on two inputs: your daily usage and current stock. It does the math for you, showing both the total needed for 30 days and any additional refill required.

Steps to Use the Calculator

  1. Enter Daily Usage
    Input the amount of the item you use each day in the “Daily Usage” field. You can use decimals for precision. For example, if you consume 1.5 liters of milk daily, enter 1.5.
  2. Enter Current Stock
    Enter the quantity of stock you already have in the “Current Stock” field. For instance, if you currently have 20 liters of milk, enter 20.
  3. Click Calculate
    Press the Calculate button. The tool will instantly display:
    • Total Needed for 30 Days: The total quantity required for a month based on your daily usage.
    • Additional Refill Required: The amount you need to purchase to cover the 30-day period, considering your current stock.
  4. Reset if Needed
    To clear the fields and start fresh, click the Reset button. This reloads the calculator and allows you to enter new values.

Example Usage

Let’s say you want to calculate the refill for coffee in your office:

  • Daily Usage: 2 kg
  • Current Stock: 35 kg

Calculation:

  • Total Needed for 30 Days = 2 × 30 = 60 kg
  • Additional Refill Required = 60 − 35 = 25 kg

The calculator will display 60 kg as the total needed and 25 kg as the additional refill required. This ensures your office never runs out of coffee mid-month.
