Retirement brings new opportunities, priorities and expenses. As you approach this milestone, it's helpful to develop a clearer picture of what your retirement lifestyle may cost and how those costs could change over time. But how much should you plan for?

Understanding your future spending can help you set realistic savings goals and determine how much income you'll need to support your desired lifestyle. An Ameriprise financial advisor can help you refine your projections and build an income strategy tailored to your retirement goals.

Here are seven steps to help you calculate your retirement spending needs.

1. Start from your current income 

A common guideline is to expect to spend 70% to 80% of your current income in retirement, so a good first step is to calculate that number. If your pre-retirement income is $200,000, for example, you can expect your retirement spending to fall somewhere around $140,000 to $160,000 a year. However, this number may not be as helpful if you plan to change your lifestyle significantly during retirement.

2. Track your current spending 

To estimate your future retirement expenses more accurately, it can be helpful to track your spending habits in the year or two before retirement. Reviewing your bank and credit card statements before you retire can give you a good sense of where you’re spending your money and how much income you’ll actually need.  

For example, you may discover that you are spending a considerable amount of money on commuting costs — an expense that could potentially disappear in retirement. Ask yourself: How might your current spending differ from your future spending?

3. Think about the lifestyle you want 

Think about the life you’d like to lead in retirement and how it may impact your bottom line. Spending much of your time gardening or volunteering will have a much different impact on your finances than continuing to work part-time, collecting cars or traveling extensively.  

One way to help clarify how your lifestyle will affect your financial situation is by dividing your anticipated costs into essentials and lifestyle spending. Essentials include the recurring costs that cover your basic needs — food, housing, transportation, utilities — while lifestyle expenses include discretionary spending that enhances your life: hobbies, travel, entertainment and family. Overall, you’ll want to determine how much you may need to pursue your passions and leisure.

4. Evaluate your housing situation 

Where to live is among the biggest questions to think about when approaching retirement. It’s also a decision that can have a big impact on your expenses.  

Staying in a home you own outright may limit your housing costs, but it may also be more house than you need. Downsizing could potentially provide you with income you could use for other activities or investments, but there are financial considerations such as moving expenses, real estate transaction costs and more. Moving to another state may mean a higher cost of living — but also lower taxes.  

Whatever you decide, remember to factor in costs that go beyond rent or a mortgage. Inflation may be an issue if you’re planning on renting, while upkeep and taxes are often significant expenses for homeowners.

5. Plan for higher health care costs 

Health care costs in retirement can be substantial, even with Medicare. Everyday medical expenses such as prescription drug costs and routine medical services can add up over time. The costs can be even more significant for those with more complicated needs. And, if your income exceeds a certain threshold, you may also be subject to a Medicare premium surcharge, known as the Income-Related Monthly Adjustment (IRMAA).

Further, expenses such as long-term care aren’t covered by Medicare and can be particularly costly. As you consider your retirement, it’s important to be clear-eyed about the costs — now and in the future — so you can plan for rising medical expenses.

6. Think about your impact 

In retirement, people often have the time to help others and give back to their community. That can mean volunteering for an organization you care about, or it can mean financially supporting causes or helping a grandchild or loved one to pursue their dreams. Whatever the case may be, you’ll want to make sure to account for any lifetime gifting expenses you may have in retirement.

7. Prepare for the unexpected 

No matter your income or lifestyle, there will be a time when you need to pay for an unanticipated expense. To provide a buffer against unanticipated expenses in retirement, especially health care costs, it’s critical to have a cash reserve, as it may allow you to avoid dipping into other savings or selling investments before you want to.  

One guideline for retirees is to have a cash reserve to cover as much as 12 to 24 months of essential expenses.
