How much is it now?

Type of calculation: Calculating the value after a percentage decrease.
How to use the calculator:
Option 1 (Direct way): Use the Decreased Value CALCULATOR ("Calculate new value after percentage decrease"). Enter the old bill $1000 [Original] and the percentage drop 5% [Decrease]. The calculator will tell you the new bill amount instantly.
Option 2 (Step-by-step):
Step 1: Calculate the savings. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter the drop percentage 5 [X] and the old bill 1000 [Y]. It will show you that 5% of 1000 is the amount you saved.
Step 2: Subtract those savings from the old bill.
The formula:
We want to find the new bill after a 5% drop from 1000.
Drop amount = 5% of 1000
Drop amount = (5 / 100) × 1000 = 0.05 × 1000 = 50
New bill = Old bill - Drop amount
New bill = 1000 - 50 = 950
