How Much Should You Save for Retirement? Here’s How to Find Out

It’s the million-dollar question — quite literally: How much should I save for retirement?

There is a general rule of thumb for how much to save, which should then allow you to accumulate the amount of money you need: When saving for retirement, most financial experts recommend an annual retirement savings goal of 10% to 15% of your pretax income. High earners generally want to hit the top of that range, while low earners can typically hover closer to the bottom since Social Security may replace more of their income.

But rules of thumb are just that — general guidelines. More than likely, the amount you need to retire will depend on your future, both the known and unknown parts, such as:

• Your life expectancy.

• Your current spending and saving levels.

• Your lifestyle preferences in retirement.

Here are four ways to figure out how much money you should save for retirement.

1. Estimate how much retirement income you'll need

It can be more manageable to think about how much you need for retirement in terms of your annual income needs rather than a big multimillion-dollar nest egg.

Projecting retirement income requirements begins by taking a look at current spending.

To do that, enter your typical monthly expenses in the first column of a spreadsheet or jot them down on a piece of paper. Then do a little thinking about whether each expense will stay the same, go down, go up or — best of all — disappear in retirement. In a second column, write your best guess of what each expense will be in retirement.

Add those up, tack on other things, such as travel, that you may not budget for now but want to spend money on later. Then you will have a rough idea of your monthly spending needs in the future. Multiply by 12 to get the income you’ll need each year to meet those expenses in retirement. Compare that with your current income to arrive at what’s called a replacement ratio, or how much of your income you should aim to replace in retirement.

2. Consider other retirement rules of thumb

We noted one general rule above about how much to save. As far as how much income to replace, the rule used most often is the 80% rule, which says you should aim to replace 80% of your preretirement income. This is a loose rule: Some people suggest skewing toward 70%; some think it’s better to aim for a more conservative 90%.

To figure out where you land, consider what percentage of your income you’re saving for retirement. You’ll no longer have to save for retirement once you cross the hypothetical finish line, which means if you’re saving 15% now, you could easily live on 85% of your income without adjusting expenses. Add in Social Security, cut payroll taxes — which eat 7.65% of your income while you’re working — and you can probably adjust that income down even further.

Think about how much you're putting away for retirement right now. Are you way off the standard advice or pretty close?

3. Use a retirement calculator

A good retirement calculator will give you an assessment of where you stand in your savings progress by combining those annual spending estimates with projections. Most thorough calculators — including NerdWallet’s retirement calculator — bake in assumptions that are based on research: There will be defaults for inflation projections, life expectancy and market returns.

To get the most accurate result, you should consider whether those assumptions are correct given your situation: Is your investment strategy poised to hit the default return used by a calculator, which will probably hover around 6% or 7%? If you’re skewing toward bonds, you might want to adjust that down. Did your grandparents and great-grandparents live to 110? You’ve got good — but expensive — genes. Take those extra years you may live into account in your projections.

4. Revisit your expectations regularly

Circumstances change, and your retirement needs will change with them. Whether it’s a new job, a new baby or a new passion to travel the world once you hit 65, it makes sense to perform these retirement calculations fairly often. It’s better to adjust as you are able, rather than struggle to catch up down the road.

According to the 2024 Employee Benefit Research Institute’s retirement confidence survey, 68% of workers feel confident they will have enough money to live comfortably in retirement. That's up from 64% in 2023 but still leaves plenty of people who don't feel confident. And 60% of workers cite debt as a problem for them^[0]
