ASK THREE FINANCIAL EXPERTS how much you need to save for retirement, and you might get three different answers: a specific number, say $3 million; a figure based on future spending, such as enough to draw down 80% to 90% of your pre-retirement income every year; or a simple formula, like saving 12 times your preretirement salary.

But the real answer is more complicated than that. To get a clear idea of how much you may need for retirement, start by considering the many factors that could affect your future spending power, such as inflation, rising healthcare costs and a potential reduction in Social Security benefits if Congress doesn’t act to keep the program solvent. The good news is that the continuing rollout of provisions of SECURE Act 2.0 offers powerful new ways to save for retirement.

Even amid these uncertainties and new opportunities, it’s important to have a ballpark estimate of how much money you’ll ultimately need. To identify a target that fits your goals and priorities, work through the following four steps with your advisor. “Your financial advisor can also suggest ways to adjust your current savings and investment plan to help you close any gaps,” says Lauren Galvin, sales manager, Personal Retirement, Bank of America.

Having a clear idea of the sort of lifestyle you want in retirement will help you estimate how much it could cost. Start by thinking about your essential or nonnegotiable regular expenses, such as a roof over your head, food on the table and out-of-pocket healthcare expenses.

Then, consider expenses that are important to your lifestyle. That might be anything from dining out frequently to traveling overseas every year. Offering financial support to aging parents or helping adult children or grandchildren with education expenses might also be a priority.

Finally, consider any aspirational or discretionary goals you may have, like purchasing a second home on the beach or in the mountains, or pursuing certain philanthropic activities.

Keep in mind, too, that some essential expenses — such as your own healthcare spending — may increase in retirement, while your retirement lifestyle may shift as you age. Forty-five percent of retirees say their overall expenses are higher than they predicted.² You can use this retirement income planning worksheet to come up with an estimate of your future spending, and revisit it as your plans change. Just as you juggle and prioritize competing goals when you’re younger, you’ll need to do the same throughout retirement.

“There are multiple personal variables to weigh when starting to think about how much you’ll need to save for retirement,” says Galvin. Your current age may be among the most important, but also consider how long you expect to live. Fifty-four percent of Americans say they aim to live to the age of 100, yet only 26% expect to work past age 70.³ If you feel similarly — especially if you’re young and in good health — your retirement may last 30 years or more, Galvin notes.

No matter what your current age is, however, you may find that you end up retiring earlier (or later) than expected based on unforeseen circumstances. Either situation could affect the number of years you will need to rely on your assets for income. To help ensure your money lasts in retirement, it’s important to plan for those possibilities.

Once you have a target annual income figure in mind, you and your advisor can take an audit of all of your anticipated sources of retirement income (retirement accounts, Social Security, pensions, annuities, rental income, an inheritance or sale of a business) and calculate how much you could potentially draw from them once you retire. Your personal retirement accounts may be one of your biggest sources of income, and you could be surprised by how much — or how little — even a seemingly large retirement account could provide over the course of a long retirement. See the chart below.

You and your advisor will then be ready to talk about any adjustments you might need to make. If you’re in your mid-30s, you may have 30 years to build assets, but if you’re relatively close to retirement, a first step may be figuring out what you’re spending today and calculating whether you’re on track to support that in retirement.

“Even if you find that you’re behind where you want to be, don’t get discouraged,” advises Galvin. “There are a number of ways you can catch up.” Be sure you’ve maxed out tax-advantaged retirement plans, such as a 401(k) or IRA, and taken advantage of any employer match. If you’re 50 or over, you may be eligible for additional “catch-up” contributions. Under SECURE 2.0, those contributions will be adjusted for inflation, and those who are 60 to 63 may be able to save even more. To find out current contribution limits, see our annual limits guide.

Other tax-advantaged savings options include certain annuities and cash-value life insurance. With a high-deductible health insurance plan, you’re eligible to contribute pre-tax dollars to a health savings account, which can be rolled over year after year and used in retirement for more than healthcare costs.

A financial advisor may also suggest revisiting your investment strategy. “Asset allocation and thoughtful, goals-based portfolio management are two things that can potentially steer you to a better retirement outcome,” notes Galvin.

Remember, too, that retirement is a journey. “You can always change course if you need to — maybe by working a few years longer or adjusting your expenses,” she adds. But by starting early and planning ahead, you’ll have a far better chance of living the life you truly want in retirement.
