Assumptions and provenance
This example calculation is disclosed in full. Every quantity below enters the figures above exactly as stated — a specialist can recompute them or substitute their own assumptions.
- Payback (cumulative)
- 8 years
- Payback (discounted)
- 9 years
- Payback (static)
- 7,5 years
Sum of the nominal annual net benefits, including degradation, price escalation and replacement costs — not discounted. This is the figure shown above.
The same cash flows, discounted at the nominal rate the net present value uses. Always the later of the two.
Investment divided by the first year's benefit — without price escalation, degradation or replacement costs. Many quotes use this; depending on the assumptions it comes out shorter or longer.
