Best ways to budget to reach a million

According to our research into savings, the average adult in the UK had £16,067 in savings in 2025. Based on an interest rate of 2.62%, which is the average instant acacess savings rate in January 2025, the average Brit would save up to a million pounds by 2114 (so less than 100 years!). However, this does assume you never spend any of these savings on any big life purchases, such as buying a house or having a wedding.
