Java Program: Electricity Bill Calculation Using Slabs

Slab Rates Used in This Example

Units Consumed	Rate per Unit
0–100	₹5
101–200	₹7
201–300	₹10
Above 300	₹15

Java

import java.util.Scanner;
 
public class ElectricityBill {
    public static void main(String[] args) {
 
        Scanner sc = new Scanner(System.in);
 
        System.out.print("Enter total units consumed: ");
        int units = sc.nextInt();
 
        double bill = 0;
 
        if (units <= 100) {
            bill = units * 5;
        }
        else if (units <= 200) {
            bill = (100 * 5) + (units - 100) * 7;
        }
        else if (units <= 300) {
            bill = (100 * 5) + (100 * 7) + (units - 200) * 10;
        }
        else {
            bill = (100 * 5) + (100 * 7) + (100 * 10) + (units - 300) * 15;
        }
 
        System.out.println("Total Electricity Bill: ₹" + bill);
        sc.close();
    }
}

Output

OUTPUT 1: Enter total units consumed: 75 Total Electricity Bill: ₹375.0 Explanation: 75 units → within first slab
Bill = 75 × 5 = ₹375
OUTPUT 2: Enter total units consumed: 150 Total Electricity Bill: ₹850.0

Bill Calculation:

100 × 5 = 500
100 × 7 = 700
100 × 10 = 1000
Remaining 25 × 15 = 375

Total = 500 + 700 + 1000 + 375 = ₹2575

(Note: If needed, I can adjust slab calculations based on your electricity board.)

Explanation

✅ 1. Input

User enters total electricity units consumed.

✅ 2. Slab-wise Calculation

The program applies rates incrementally, not flat-rate.

Ex: If units = 250
→ First 100 at ₹5
→ Next 100 at ₹7
→ Remaining 50 at ₹10

✅ 3. Output

Final bill printed in Rupees.
