This study examines how youth (aged 18–30) in India and the UK differ in their consumption patterns, with a focus on spending priorities, saving behaviour, and discretionary expenditure. The aim is to understand how economic context and financial systems shape everyday money decisions among young adults. India is an emerging economy with lower average income levels, while the UK is a developed economy with higher income but higher living costs. World Bank data shows a large gap in GDP per capita between the two countries, which affects how much young people can spend after essentials. (World Bank) The study uses a mixed-method approach for its analysis. It combines secondary data from government and institutional sources with a primary online survey of 80 respondents aged 18–30 (India and UK). The findings suggest two clear differences about consumption pattern. First, UK youth spend a larger share on essential goods and services, that includes housing, which reduces overall discretionary spending. National UK survey finding shows tenants spend a good amount of money of their disposable income on housing costs. On the other hand, Indian youth show stronger saving habits and intentions, however recent evidence suggests household financial saving has weakened in recent years, alongside growing digital payment use that may encourage frequent small purchases. Overall, the results indicate that income levels, living costs, and credit/payment systems strongly influence youth spending and saving, creating meaningful differences between India and the UK.
