electricity and gas for heating, cooling and lighting.the decline in value of equipment and furniture.The shortcut method (80 cents per work hour) covers all your work from home expenses, such as: The all-inclusive temporary shortcut method was introduced from 1 March 2020 due to the COVID-19 pandemic and the increased number of employees working from home. But make sure you meet the criteria and record-keeping requirements for each method.įor the 2019–20 income year, if you worked from home before 1 March 2020, you may need to use more than one of the three methods to work out your total deduction for the year.Īccess the Home office expenses temporary shortcut method calculator You can use the method or methods that will give you the best outcome. Actual cost method – use the actual cost method.Fixed rate method (52 cents) – use the fixed rate method.Shortcut method (all-inclusive rate of 80 cents per work hour) temporary due to COVID-19 – use the shortcut method.There are three methods to calculate home office expenses depending on your circumstances: If your home is your principal place of business, you should refer to running your business from home. These can be additional running expenses such as electricity, the decline in value of equipment or furniture and phone and internet expenses. If you're an employee who works from home, you may be able to claim a deduction for expenses you incur relating to that work. that you're reimbursed for, paid directly by your employer or the decline in value of items provided by your employer – for example, a laptop or a phone.related to children and their education – this includes setting them up for online learning, teaching them at home or buying equipment such as iPads and desks.for coffee, tea, milk and other general household items your employer may otherwise have provided you with at work.Expenses you can't claimĮmployees generally can't claim occupancy expenses such as rent, mortgage interest, water and rates.Įmployees who work at home can't claim costs: Use these results as an estimate and for guidance purposes only. Your results are based on the information you provide and the rates available at the time of calculation.

Power Out = Energy Out * Generator Efficiency.Energy Out = ( Inlet Specific Enthalpy - Outlet Specific Enthalpy) * Mass Flow.Step 4: Calculate Steam Turbine Energy Out and Generation (Power Out) Using the outlet specific enthalpy, calculate the outlet properties: Outlet Specific Enthalpy = Inlet Specific Enthalpy - Isentropic Efficiency * ( Inlet Specific Enthalpy - IDEAL Outlet Specific Enthalpy).( Inlet Specific Enthalpy - Outlet Specific Enthalpy) Isentropic Efficiency * ( Inlet Specific Enthalpy - IDEAL Outlet Specific Enthalpy) =.Step 3: If solve for 'Outlet Properties', Determine Outlet Specific Enthalpy ( Inlet Specific Enthalpy - IDEAL Outlet Specific Enthalpy) Isentropic Efficiency = ( Inlet Specific Enthalpy - Outlet Specific Enthalpy) /.Step 3: If solve for 'Isentropic Efficiency', Determine Outlet Properties Using the outlet specific enthalpy, calculate the isentropic efficiency: Step 2: Calculate Ideal Outlet Properties (Inlet Entropy equals Outlet Entropy) Inlet Energy Flow = Specific Enthalpy * Mass Flow.The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Calculation Details and Assumptions belowĬalculation Details Step 1: Determine Inlet Properties Using the Steam Property Calculator, properties are determined using Inlet Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality).
