Net Zero Go has developed an appraisal tool that can be used for an initial financial assessment of different options.
The tool has been built on Microsoft Excel and it is intended to be used funding and investment options stage

The Financial appraisal tool enables the comparison between Costs (or Expenditures) and Earnings Before Income Tax Depreciation Amortisation (EBITDA). The tool calculates the Net Present Value (NPV), Internal Rate of Return (IRR), Simple Payback Time, and Discounted Payback Time. The inputs required have been kept to a minimum to allow easy use and quick implementation.
The tool uses expenditures and revenues as input to calculate the key financial parameters, Net Present Value, Internal Rate of Return, and payback time.
Once completing a first case, the user can assess the profitability of different solutions by comparing multiple cases. A final “Cases Comparison” page presents a summary of the key financial parameters for all the cases.
