The NMC calculation is regulated by current legislation and is based on several methods. The key ones are the method of comparable market prices (market analysis), normative, tariff, project-estimate, and cost methods. The choice of method depends on the procurement object, the availability of information, and the market specifics.
The most common method is market analysis. It involves collecting and processing commercial offers, data from open sources, and contract registries. The calculation can be represented by the formula:
NMC = (P1 + P2 + ... + Pn) / n
where P is the price of a similar product, work, or service, n is the number of sources of information. It is important to consider the comparability of conditions: volume, delivery times, region, and other parameters.
In the case of regulated prices, the tariff method is applied, where the calculation is based on state-established tariffs. The project-estimate method is predominantly used in construction and is based on approved estimate documentation.
For complex or unique procurements, the cost method may be used, which includes calculating the cost price taking into account profit. The normative method is used if mandatory norms and standards are established for the procurement object.
| Method | Calculation Basis |
|---|---|
| Market Analysis | Commercial offers, contract registries |
| Tariff | State tariffs |
| Project-Estimate | Estimate documentation |
| Cost | Cost price and profit |
| Normative | Established norms |
Accurate determination of the NMC is crucial to ensure transparency in procurement, compliance with competition principles, and efficient use of budget funds.
