Market Size for Banks in 2026 [Example]

The total available market (TAM) for banking services is vast. It includes individuals who use various banking products such as savings accounts, loans, credit cards, and investment services. Globally, there are approximately 5 billion adults, and assuming a conservative average banking spending of $1,000 per person annually, the total money figure comes to around $5 trillion in the banking sector worldwide, encompassing all potential banking customers, including unbanked populations and varying banking service usages.

The serviceable addressable market (SAM) would focus on individuals who can access traditional banking services. Considering that around 1 billion adults globally are actively using banks or financial institutions, with an average yearly spend of $1,000 on banking fees and services, the SAM money figure amounts to approximately $1 trillion. This estimation accounts for geographical limitations and the market penetration of banking services in different regions.

The serviceable obtainable market (SOM) looks at what portion of the SAM can realistically be captured in the first year. If we realistically aim for 10% of the SAM within one year, we can project around 100 million individuals becoming customers, bringing the SOM money figure to approximately $100 billion. This assumes successful marketing and the ability to convert potential customers within niches, keeping in mind the competitive nature of the banking industry.
