TAM stands for\u00a0Total Addressable Market<\/strong>\u00a0and refers to the total theoretical sales potential that a product or service could achieve within a defined market.<\/p>\n

The TAM illustrates the size of the market opportunity if a company were to serve all potential customers and achieve a market share of 100 per cent. Current constraints such as competition, sales resources or geographical reach are not taken into account at this stage.<\/p>\n

TAM forms part of the market size analysis alongside SAM and SOM:<\/p>\n\n\n\n\n\n\n\n
Key figure<\/strong><\/td>\nMeaning<\/strong><\/td>\n<\/tr>\n<\/thead>\n
TAM<\/strong><\/td>\ntotal theoretically addressable market<\/td>\n<\/tr>\n
SAM<\/strong><\/td>\nThe part of the market that the company is, in principle, able to serve with its current range of products<\/td>\n<\/tr>\n
SOM<\/strong><\/td>\nThe share of the market that the company can realistically achieve<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

One example:<\/p>\n

A start-up is developing software for manufacturing companies. The Total Addressable Market (TAM) comprises all companies worldwide that could, in principle, have a need for such a solution. If the start-up initially offers its software only to medium-sized companies in Germany, this smaller market corresponds to the Selectable Addressable Market (SAM). The share that can realistically be captured over the next few years constitutes the Selectable Operating Market (SOM).<\/p>\n

Various methods can be used to calculate the TAM:<\/p>\n

Top-down approach<\/strong><\/p>\n

The top-down approach makes use of existing market studies and industry reports. Segments that are not relevant are excluded from the overall market size.<\/p>\n

bottom-up approach<\/strong><\/p>\n

In the bottom-up approach, the market is calculated on the basis of specific customer data:<\/p>\n

Number of potential customers \u00d7 average annual revenue per customer = TAM<\/strong><\/p>\n

One example:<\/p>\n\n\n\n\n\n\n\n
Key figure<\/strong><\/td>\nValue<\/strong><\/td>\n<\/tr>\n<\/thead>\n
Potential customers<\/td>\n100.000<\/td>\n<\/tr>\n
Average annual turnover per customer<\/td>\n5.000 \u20ac<\/td>\n<\/tr>\n
TAM<\/td>\n\u20ac500 million<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

In this example, the theoretical annual market potential amounts to 500 million euros.<\/p>\n

Value Theory approach<\/strong><\/p>\n

For new products where there is no existing comparable market, the TAM can be estimated on the basis of the economic value created. This involves analysing the added value the solution offers to customers and the proportion of that value the company could charge as a price.<\/p>\n

The TAM analysis helps start-ups to:<\/p>\n

    \n
  • to assess the overall scale of a market opportunity<\/li>\n
  • to compare different business ideas or market segments<\/li>\n
  • to develop long-term growth strategies<\/li>\n
  • To identify opportunities for expansion<\/li>\n
  • to better assess capital requirements<\/li>\n
  • To convey the economic potential of the business model to investors<\/li>\n<\/ul>\n

    However, a large TAM does not automatically mean that a start-up will be successful. The crucial factor is which part of the market actually matches the offering and can be reached with the resources available.<\/p>\n

    Common errors in TAM calculations include:<\/p>\n

      \n
    • a definition of the market that is too broad<\/li>\n
    • Inclusion of customers without a genuine need<\/li>\n
    • unrealistic price assumptions<\/li>\n
    • Mixing of TAM, SAM and SOM<\/li>\n
    • Use of out-of-date or unsuitable market data<\/li>\n
    • the assumption that even a small percentage of a large market is easily within reach<\/li>\n<\/ul>\n

      Statements such as \u201eWe only need to capture one per cent of the global market\u201c are therefore not very robust. A convincing market analysis clearly explains which customers are being targeted, what revenue can be generated per customer, and how the start-up intends to reach this target group.<\/p>\n

      innoWerft helps founders to clearly define their target markets, calculate market potential based on transparent assumptions, and present TAM, SAM and SOM in a way that is easy to understand for business planning and discussions with investors.<\/p>","protected":false},"excerpt":{"rendered":"
