Welcome to Electricity Bill Calculator App! By using this user friendly app. you can precisely calculate your monthly electricity bill of your house inserting the input of unit (kW-hr). The app is designed based on following formula of electricity bill calculation:

If the number of units consumed is less than or equal to 50, the rate per unit is 0.50, and the bill is calculated by multiplying the number of units by 0.50.
If the number of units consumed is between 51 and 150, the first 50 units are charged at 0.50, and the remaining units are charged at a rate of 0.75 per unit. So, the bill is calculated as 25 + ((units - 50) * 0.75).
If the number of units consumed is between 151 and 250, the first 50 units are charged at 0.50, the next 100 units are charged at 0.75, and the remaining units are charged at a rate of 1.20 per unit. So, the bill is calculated as 100 + ((units - 150) * 1.20).
If the number of units consumed is more than 250, the first 50 units are charged at 0.50, the next 100 units are charged at 0.75, the next 100 units are charged at 1.20, and the remaining units are charged at a rate of 1.50 per unit. So, the bill is calculated as 220 + ((units - 250) * 1.50).
