How Much Money Will I Need in Retirement?

by | Jul 23, 2025

Question: How much money will I need to maintain my current standard of living when I retire?

Answer: There are key principles and simple calculations you can use now, to estimate how much money you'll need in retirement.

Income Replacement Rate:

Many financial advisers recommend planning for 70% to 80% of your pre-retirement income to maintain your current lifestyle in retirement. For example, if you earn €60,000 per year before retirement, you should plan for €42,000 to €48,000 per year in retirement. 

Personalisation Matters: Your actual needs may vary depending on your health, location, housing situation, and lifestyle choices. Creating a detailed budget based on anticipated expenses is the most accurate approach.

The 25x Rule

Multiply your expected annual retirement expenses by 25 to estimate the total savings needed. This is a very ‘rough and ready’ guide but some may find it useful.

Example: 
If you need €50,000 per year: 

€50,000 × 25 = €1,250,000  

 This assumes a sustainable 4% annual withdrawal rate from your investments 

How to Estimate Your Retirement Need

For a more analytical method, consult a financial planner and ask about cash flow planning. For this, you will need to come prepared with the following information- 

1. Estimate Your Annual Retirement Expenses: 

  • Housing (including maintenance) 
  • Healthcare 
  • Food and utilities 
  • Transportation 
  • Entertainment, travel, and hobbies 
  • Taxes and insurance

2. Estimated Income 

  • Include benefits, pensions, or rental income 
  • Details of current investments and savings  
Important Considerations

To estimate how much money you’ll need in retirement, consider how life could change:

  • Healthcare costs often rise in retirement—plan for higher medical expenses. 
  • Lifestyle changes (downsizing, relocating, travel) can increase or decrease your needs. 
  • Longevity: Plan for a retirement that could last 30 years or more.
