LLCR calculator for project finance cover

An LLCR calculator computes the loan life cover ratio: the net present value of cash flow available for debt service over the remaining scheduled loan life, divided by outstanding debt at the test date. AFME's project finance discussion paper defines LLCR as the discounted sum of cash flows over the loan life divided by the debt amount, with an LLCR above 1 meaning that project cash flows can cover debt service with a certain level of cushion. World Bank project appraisal work uses the same measure in practice: the Croatia roads sector modernization project set a ten-year Loan Life Coverage Ratio as one of its debt service capacity indicators.

LLCR calculator formula

LLCR = NPV(CFADS from test date through final scheduled maturity) / outstanding debt at test date

Common modelling conventions:

• discount CFADS at the cost of the measured debt (or the rate stated in the facility)
• stop the CFADS series at final maturity of that debt; cash after maturity is excluded
• use opening outstanding principal for the test period as the denominator unless the term sheet states otherwise
• state expressly whether the debt service reserve account balance is added to the numerator

LLCR differs from period DSCR, which tests one period of CFADS against that period's debt service. It also differs from PLCR, which extends CFADS to remaining project or asset life rather than loan maturity.

Inputs

• Outstanding debt: senior (or measured) principal at the test date
• CFADS forecast: periodic cash available for debt service from the test date to final maturity
• Payment frequency: quarterly, semi-annual or annual CFADS buckets matching the model
• Discount rate: cost of debt or facility-defined LLCR rate
• Maturity date: final scheduled repayment of the measured debt
• DSRA treatment: include or exclude reserve balance in the numerator
• Case: base, downside or rating-agency case as used in the credit paper

Worked numerical example

Illustrative annual model, test date at financial year start, three years remaining to maturity, discount rate 8 percent, outstanding debt 100.0 million. DSRA excluded.

Projected CFADS:

• Year 1: 28.0 million
• Year 2: 30.0 million
• Year 3: 32.0 million

NPV at 8 percent (end-of-year convention for illustration):

• Year 1: 28.0 / 1.08 = 25.93
• Year 2: 30.0 / 1.08^2 = 25.72
• Year 3: 32.0 / 1.08^3 = 25.40
• NPV total = 77.05 million

LLCR = 77.05 / 100.0 = 0.77x

Coverage below 1.0x means the present value of remaining CFADS does not cover outstanding debt on these assumptions. Raising CFADS, extending amortisation inside the permitted tenor, cutting leverage or adding contracted support changes the inputs; the calculator only restates the ratio.

If the term sheet adds a 12.0 million DSRA to the numerator, NPV-plus-DSRA = 89.05 and LLCR = 0.89x. Reported coverage rises without any change in operating CFADS, which is why DSRA treatment is disclosed beside the result.

Interpretation limits

An LLCR calculator is only as sound as the CFADS forecast and discount convention. Optimistic ramp-up, incomplete major-maintenance timing or inconsistent tax and reserve logic distort the NPV. Semi-annual versus annual discounting, mid-period versus end-period assumptions, and whether default interest or fees enter CFADS all move the number.

LLCR does not measure a single payment period and does not replace DSCR covenant testing. It does not value residual cash after loan maturity; that is the PLCR question. AFME notes that because asset life often exceeds original loan maturity, PLCR informs restructuring options that postpone maturity when cash flow is short. Desks read LLCR alongside the cash waterfall and reserve mechanics that define CFADS in project finance models.

The calculator does not publish a market-standard minimum. AFME's "above 1" statement is a coverage identity, not a bank policy floor. Sector risk, offtake quality and sculpting drive the hurdle used in term sheets.
