A salary of £100,000 per year is considered very good in the UK. The average annual salary in the UK in 2023 is around £30,000 & people earning over £80,000 are in the top 5% of earners.

However, the cost of living can vary widely depending on where in the UK you live. For example, living in London or other parts of the South East is generally more expensive than living in the North or in Scotland. Housing costs, in particular, can be a significant factor in your cost of living.

Even in expensive areas, a £100,000 salary would afford a comfortable lifestyle, though how comfortable depends on one's personal circumstances, financial responsibilities & longer term considerations including saving for retirement. For example, if you have a large family to support, significant debts, or other financial obligations, your money may not go as far as it would for someone without these responsibilities.

General Savings

The 50/30/20 Rule - experts suggest spending 50% of your income on essentials, 30% on your optional things you want, leaving you with a target 20% to put into savings for a ‘rainy day’ or home refurbishments, a holiday or a new car for example.

Retirement Planning

A Good rule of thumb suggested by experts is to divide your age in half & save that amount into a pension as a percentage of your gross income. If for example you are 40, you should be investing 20% of your monthly income in a pension with the aim of achieving a final pension pot on retirement of ten times your average salary.
