In the UK the QALY is most frequently used as the measure of health effect, enabling ICERs to be compared across disease areas, but in other healthcare systems other measures of health effect may be used. In decision-making ICERs are most useful when the new intervention is more costly but generates improved health effect. ICERs reported by economic evaluations are compared with a pre-determined threshold (see Cost-effectiveness threshold) in order to decide whether choosing the new intervention is an efficient use of resources. By knowing the additional cost incurred to produce one more unit, a company can set prices that cover both variable costs and contribute towards fixed costs and desired profit margins. Marginal cost is the additional cost incurred in the production of one more unit of a good or service.

• Simply put, marginal cost is the change in the cost for production when you decide to produce one more unit of a good.
• Where C0, text style C 0, and E0, text style E 0, respectively, represent the cost and impact in the control care group, and where C1, text style C 1, and E1 display style E 1, respectively.

If the modification goes ahead, Zob Co will have to pay $1,417.50 more in variable costs. Now let us consider the increased output – this will affect both bookkeeping for startups revenue and variable costs. If the modification takes place, Zob Co will receive an extra $1,000 of income, so the incremental cash flow is an inflow.

For example, the table below depicts the production quantities and costs of a firm that produces orange juice. Marginal cost is the extra cost incurred in producing one more unit of a product. Simply put, marginal cost is the change in the cost for production when you decide to produce one more unit of a good.

These cash flows can then be used further to, for example, decide if the modification should take place, by calculating the net present value of the incremental flows. Anything that has occurred in the past is referred to as a sunk cost and should be excluded from relevant cash flows. A definition often used for relevant cash flows states that they must be cash flows that occur in the future and are incremental. Please note that the concept of marginal cost is applicable in the short run, where some costs may vary with the level of production while others remain fixed. Marginal cost (MC) is the additional cost of producing one more unit of a good or service.

As well as the main clinical outcome (smoking abstinence), the CUA considered health-related quality of life at 12 months, measured using the EuroQol EQ-5D. For example, the cost per QALY threshold by NICE for England and Wales is between £20,000 and £30,000. The example digital product for managing heart failure would be judged highly cost-effective because its ICER (£1,000 per QALY) is well below this threshold.

They tend to have the highest value at the start of their life cycle and decrease in value (depreciate) as their life cycle draws to a close. However, when used in the Costs Calculator options 1 and 2 give some perverse results. To explain this, the results we obtained from our worked examples above are summarised again in table 5.
