how to retire early in 5 steps

Most people who dream of early retirement would define this as retiring in their early 40s or 50s.  This is no easy feat and requires a lot of work and dedication as you will need to finance your retirement because the earliest you can start receiving the state pension is 67. Retiring early is often referred to as FIRE. This stands for financial independence, retire early. This is less about retiring early but having complete financial independence to do as you please and to work when you want. After all, there is only so much golf you can play or travelling you can do and work may still play a small part of your life. Essentially what we are saying is that retiring = financial independence.

1. Estimate your level of savings

In the article ‘How much money do I need to save for my retirement?’ A projected 10 to 16 times savings to annual income is required at a retirement age of 55 to 65. 

To do this at an earlier age would require considerably larger savings. A figure of 25 is commonly used by early retirees. This means you should have 25 times your planned annual savings before you retire. 

This means that if you spend £30,000 during your first year in retirement, you will require savings of £750,000 when you quit your day job.

However, a modest income of £20,000 means you only require savings of £500,000, Of course, this £20,000 could be supplemented by part-time work. This is good motivation to get your budget in check as this scenario is considerably more achievable. 

The second rule says that your retirement fund is invested and it will continue to grow as your spending will rise each year due to inflation.

The third rule is the 4% rule can provide a sustainable income during early retirement originated from research in the 1990s. This is a guideline for retirement planning that suggests withdrawing 4% of your initial retirement portfolio balance in the first year of retirement and adjusting that amount for inflation in subsequent years to achieve the same buying power. 

Table 1. Illustrates first two years at 5% growth can be sustained with an income drawdown of 4%% adjusted in the second and third year with 5% inflation.

Withdraw 4% Funds invested 5% growth
  £750,000 £787,500
£30,000 £757,500 £795,375
£31,500 £763,875 £802,068
£33,075

£768,993

 

 

This is not foolproof as you probably be hard-pressed to find a financial advisor that would guarantee this as an income for life due to the uncertainty of inflation and investment returns. But it is considered a reasonable strategy.

2. Reducing what you spend

To get to an investment fund of £750,000 in your 30s or 40s is quite an achievement and either requires good fortune or hard work and discipline. Many FIRE devotees aim to get their spending down to 50% of their income. The rest gets saved!

The cornerstone of a FIRE devotee is that eliminating debt, including what's traditionally considered "good" debt like mortgage loans, can indeed be a crucial financial goal. 

Cutting both large and small expenses is also an effective way to improve your financial situation. Being creative and finding ways to save on transportation, utilities, food, and housing costs can help you free up more funds for savings and debt repayment.

Setting up a company and having all of your income paid into this, is a neat way of reducing income tax as the savings effectively grows in the company. The central premise is that corporation tax would be lower than paying tax as a higher rate taxpayer.

3. How much money do you need in retirement?

Calculating your annual retirement needs by adding up your final monthly expense estimates and then adding a 10% to 20% buffer is a prudent approach. 

Having that extra cushion can provide financial flexibility during retirement for unexpected expenses or the occasional indulgence. 

This method can help you set a more realistic target for your retirement savings and ensure that you're well-prepared for your financial needs in retirement.

4. Invest for growth

As you approach your planned early retirement you will likely want to shift a small amount of your savings into safer, more liquid havens, perhaps one or two years' income so you can maintain your income without worrying about selling investments at a loss so your money grows thereby supporting the 4% distribution rate mentioned earlier.

The rest of the funds should be invested to maximise your returns with a balanced portfolio designed for long-term growth is a sound strategy. 

Early retirees often have a longer retirement period to cover. This longer time frame can allow for a more aggressive investment approach. 

Low-cost index funds can be an excellent choice for their diversification and cost-efficiency.

Riskier assets like stocks can offer significant long-term growth potential as you may have more time to ride out market fluctuations and benefit from the potential growth.

5. Keep a check on your expenses

Without stating the obvious, running out of money means going back to work.

It's paramount that you stick to the 4% rule. It is designed to allow for spending increases due to inflation, but not large purchases that incur a debt such as buying a car on finance.

Each new spending increase, especially recurring expenses like additional debt payments, can impact your financial security in retirement. 

It's essential to manage and track your expenses carefully to ensure they align with your retirement income.
