How Much Do You Need to Save Each Month to Become a Millionaire?

Not everybody can get on (and win) Who Wants to Be a Millionaire or Beast Games. But with enough time and consistency, saving and investing your way to $1 million is within reach for a lot more people than you might think.

How much do you need to save each month to reach $1 million by 60?

Assuming a hypothetical 7% average annual return, here's roughly how much you'd need to invest every month to reach $1 million by age 60, depending on when you start:

Start at 20: about $380 per month (roughly $183,000 contributed over 40 years)

Start at 30: about $820 per month (roughly $295,000 contributed over 30 years)

Start at 40: about $1,920 per month (roughly $461,000 contributed over 20 years)

Start at 50: about $5,780 per month (roughly $693,000 contributed over 10 years)

This is a hypothetical illustration that assumes monthly contributions and a 7% average annual return compounded monthly. It is not a guarantee of future results and does not represent any specific investment. Actual returns will vary and may be lower. It does not account for taxes, fees, or inflation.

Why does waiting cost so much?

Every decade you wait, the monthly number more than doubles. That's the real cost of waiting, and it's why starting early is one of the most powerful advantages you have.

The reason is compounding. Look at the total contributions above. If you start at 20, you put in about $183,000 of your own money, and growth does most of the heavy lifting over 40 years. If you start at 50, you have to contribute about $693,000 yourself because there's far less time for growth to do the work.

Is $1 million the right retirement goal?

Here's the thing: $1 million is probably the wrong question to ask.

It might be the number in your head, and that might just be because it's a nice round number. The real question is how much you need, after taxes, to live the lifestyle you want and accomplish all of your goals.

It might be more than $1 million. It might be less. It completely depends on what else is going on in your life.

What's working for you when you retire

When people think about how much money they need to retire, there are a few factors I see overlooked fairly often.

You stop saving for retirement. If you're no longer setting money aside for retirement, that alone is a big boost to cash flow. The dollars you were contributing to your 401(k) or IRA every month are now available to spend.

Your portfolio isn't your only source of income. You may have a combination of Social Security, pensions, annuities, rental or business income, and investment income. Every dollar that comes from those sources is a dollar your portfolio doesn't have to cover.

Some big expenses may disappear. Mortgages might be paid off. You might not have a car payment. Commuting costs, work wardrobes, and expenses tied to raising kids often shrink or go away entirely.

Put those together and your savings may only need to cover the gap between what you spend and what your other income sources provide. That gap is often smaller than people expect.

What's working against you when you retire

The biggest risks in retirement are often inflation, taxes, sequence of returns risk, and medical expenses. None of these are reasons to panic. They're all things that can be planned for.

Inflation. Retirement can last 30 years or more. Over that kind of timeframe, even modest inflation can meaningfully reduce what your money buys, so your income plan needs room to grow.

Taxes. Not all retirement dollars are equal. Withdrawals from traditional 401(k)s and IRAs are generally taxed as ordinary income, while qualified Roth withdrawals generally aren't. A million dollars in a pre-tax account and a million dollars in a Roth account can provide very different amounts of spendable income.

Sequence of returns risk. The order of your returns matters once you start withdrawing. A significant market decline in the first few years of retirement, while you're pulling money out, can have a much bigger impact than the same decline later on.

Medical expenses. Healthcare is one of the harder costs to predict. Medicare doesn't cover everything, and premiums, out-of-pocket costs, and potential long-term care needs are worth building into your plan.

How to figure out your real retirement number

Instead of starting with a round number, start with your life:

Estimate what you'll actually spend each year in retirement, including the things you want to do, not just the bills.

Add up your expected income from Social Security, pensions, and any other sources.

Find the gap between the two. That's what your savings need to cover.

Adjust for taxes and inflation, and stress-test the plan against a rough market early on.

The takeaway

Focus on the result you want, and have a plan to get there while mitigating the risks you can. Everything on top of that is a bonus.
