# Energy costs using high-low method

Registered Posts: 3
Can any one help me. I have a mental block! I am working through a practice assessment on the AAT website. I am completing a budget for an alternative scenario. I am stuck on how to calculate the energy costs.

Operating budget: Energy costs £43,000
Assumption in the first scenario: there is an allowance for an energy price rise of 7.5%
Alternative scenario: revise the energy price rise to 10%

I have an exam tomorrow and have a complete block on how to do this.

If the £43,000 figure is before any changes, then
First scenario: £43,000 + 7.5% = £46,225
Alternative: £43,000 + 10% = £47.300

If the £43,000 is actually the first scenario (after the 7.5% rise), then
Cost before 7.5% rise = 43,000 / 1.075 = £40,000
Alternative: £40,000 + 10% = £44,000
