Free project finance tool
DSCR and indicative debt capacity calculator.
Use annual CFADS, your target coverage ratio, interest rate and tenor to get a quick sense of how much level debt service the project could carry.
What the calculator is doing
CFADS is simplified here as contracted revenue less operating costs and the other pre-debt cash deductions you enter. Maximum annual debt service equals CFADS divided by the target DSCR. Indicative debt capacity is the present value of that level annual debt service over the selected tenor.
- It assumes one annual period and level debt service.
- It does not sculpt debt to a changing CFADS profile.
- It does not model construction draws, IDC, reserve accounts, tax shields, fees, covenants or refinancing.

Coverage is only useful when you know what sits inside CFADS.
For a real renewable energy financing, the next step is to build the period-by-period cash flow and check the weakest year, not just an annual average. Generation, tariff escalation, operating costs, tax, reserves and payment delays can all change the debt service the project can safely carry.
