Gas and Electric Home use Calculator

Project Description for Home Gas & Electricity used Price Calculator Introduction: It is difficult to work out accurately the cost of domestic Gas and Electric in the UK. The problem is that bills are quarterly and based on estimated readings. The purpose of this application is to allow domestic/business Gas and Electric users to be able to calculate the daily/weekly/monthly cost of the Gas & Electric actually used by entering Meter Readings and Billing Rates (Tariffs). Inputs: Meter Reading Gas & Date Meter Reading Electric & Date Cost per KWh Electric for first X units used Cost per KWh Electric for units used after first X Cost per KWh Gas for first X units used (Meters or Feet) Cost per KWh Gas for units used after first X Volume Conversion Factor (VCF) currently 1.0226400 taken from Bill Calorific Value (CV) currently 39.3521 taken from Bill Note the formula to convert the Gas Meter Reading (UK - Cubic Meters or North American Cubic Feet?) to the billing Value (kilo Watt hour KWh) is simply Meter Reading in Cubic Meters X Volume Conversion Factor X Calorific Value divided by 3.6. An option for entering North American Data (cubic feet I think?) will need to be a selectable option. The formula for Electric is just Kwh Reading X Billing rate. Outputs: Digital (numerical) and graphical display of Gas & Electric usage selectable for daily/Weekly & Monthly: Additional Information: There is a complication in that the suppliers typically charge a rate for the first X units used and then reduce the rate. This will need to be taken into account in the calculations. A further complication is that results may cover multiple Tariff and Meter Readings and will need to be calculated from this information. Password protection should be provided (single common password OK) Context Help should be built into all input points (Pop up on Hover?) Approximate start date of the project after selecting a bid within one week.
