How Much Money Will I Need in Retirement?

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.
