How much is it now?
Type of calculation: Calculating the value after a percentage decrease.
Calculator usage:
Option 1 (Direct method): Use the Decreased Value CALCULATOR ("Calculate new value after percentage decrease"). Enter the bill before modernization $1000 (Original) and the percentage drop 5% (Decrease). The calculator will directly give you the new bill amount.
Option 2 (Step-by-step method):
Step 1: Calculate by how much the bill dropped. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter the percentage drop as 5 (X) and the bill before modernization as 1000 (Y). The calculator will calculate 5% of 1000.
Step 2: Subtract the drop amount calculated in Step 1 from the bill before modernization.
Explanation using a formula:
We are looking for the new bill amount after a 5% drop from 1000.
Amount of drop = 5% of 1000
Amount of drop = (5 / 100) × 1000 = 0.05 × 1000 = 50
New bill = Bill before modernization - Amount of drop
New bill = 1000 - 50 = 950
