Relative calculator.

Step pricing calculation (calculate electricity fee).

Ladder electricity pricing is a method of calculating electricity consumption charges based on a tiered pricing structure. The more electricity you use, the higher the rate you will be charged. Depending on the pricing plan, the first tier may cover a low usage amount at a lower rate, and as you use more electricity, the price per kilowatt-hour will increase in subsequent tiers. This encourages consumers to conserve electricity and avoid high usage charges. The total electricity bill will be calculated by multiplying the number of kilowatt-hours used in each tier by the corresponding rate and adding them up.

Step pricing calculation (calculating electricity consumption).

Ladder electricity pricing is a method of calculating electricity usage that charges different rates for different levels of consumption. Typically, the more electricity that is consumed, the higher the rate that is charged. This is designed to encourage people to conserve energy and reduce their overall electricity usage. The exact pricing structure varies depending on the region and the electricity provider, but the general principle remains the same. Customers are charged a set amount per kilowatt-hour (kWh) of electricity used, with the rate increasing as their consumption climbs higher up the ladder.
