Best ways to budget to reach a million

According to our research into saving habits, the average adult in Britain had £6,760 saved in their account in 2020, and saves £600 per month. Based on an interest rate of 1.4%, which is the average rate for premium bonds, the average Brit would save up to a million pounds by 2098.

Historical interest rates were much higher, as our research shows that in the 2000’s Brits were enjoying an average interest rate of 4.45% on their accounts. If, in 2021, someone had an interest rate of up to 4.45%, they would be able to save a million pounds by the year 2065 if they were putting £600 per month away and already had £6,760 saved up prior to that.

However, the average interest rate for most accounts in the UK has dropped to 0.25%. Unfortunately, this is bad news for savers, as it would mean saving up to a million wouldn’t be accomplishable within 200 years unless they increased their monthly savings up to £800 at least (this would make it possible to save a million by 2114).

Finder analysts built the calculator by using a mathematical formula to calculate whether users will be able to save up to a million pounds within the next 200 years. This formula relies on the interest rate on users’ saving accounts, their monthly savings and their current savings amount.
