How to Calculate How Much You Need for Retirement

Retirement planning can feel overwhelming, but breaking it down into simple steps makes it much more manageable. The key to a successful retirement is ensuring you have enough savings to cover your future expenses while factoring in inflation, investment growth, and income sources like Social Security. In this guide, we’ll walk you through how to calculate your retirement savings goal so you can retire with confidence.

Step 1: Estimate Your Annual Retirement Expenses

Start by estimating how much money you’ll need each year in retirement. While some expenses may decrease (such as commuting costs or work-related expenses), others—like healthcare—might rise. Common retirement expenses include:

• Housing – Mortgage/rent, property taxes, maintenance, HOA fees

• Healthcare – Insurance premiums, out-of-pocket medical costs, long-term care

• Daily living – Groceries, utilities, transportation, entertainment

• Travel & Leisure – Vacations, hobbies, dining out

• Taxes – Income tax, property tax, capital gains tax on withdrawals

A common rule of thumb is that retirees spend 70-80% of their pre-retirement income annually. However, this varies depending on your lifestyle and location. If you currently make $100,000 per year, you might aim for $70,000 to $80,000 per year in retirement.

Step 2: Calculate Your Retirement Income Needs

Once you have an estimate of your yearly retirement expenses, you’ll need to project how much you’ll need in total. But don’t forget about inflation—what costs $50,000 today will cost much more in 20 or 30 years.

Example Calculation (Including Inflation)

Let’s say you estimate needing $50,000 per year in today’s dollars. If you plan to retire in 20 years and assume a 3% annual inflation rate, your future yearly expenses will be:

So, you’ll actually need $90,000 per year in 20 years to maintain the same lifestyle.

Step 3: Use the 4% Rule to Determine Your Savings Goal

A popular guideline for retirement planning is the 4% rule, which suggests that if you withdraw 4% of your retirement savings per year, your money should last 30 years. This means your total savings goal should be:

Using our previous example:

So, you would need $2.25 million in retirement savings to safely withdraw $90,000 per year.

Step 4: Factor in Other Income Sources

If you have other income sources in retirement, you can subtract those from your savings goal. Common sources include:

• Social Security

• Pensions

• Rental income

• Part-time work

Example Adjusted for Social Security

If Social Security is expected to provide $30,000 per year, your shortfall is:

Now, using the 4% rule:

With Social Security, your savings goal drops from $2.25 million to $1.5 million.

Step 5: Adjust for Inflation & Market Returns

Since your savings will be invested, you’ll also want to consider investment growth and inflation. If you have 20+ years until retirement, assume an average 6-7% annual return on investments and 3% inflation.

Using a retirement calculator can help fine-tune your numbers based on different scenarios, like retiring earlier or delaying Social Security.
