How Much Do I Need to Retire? A Simple Guide for Hourly Workers

How much do you need to retire? It is one of the most important financial questions you can ask, and most people either have no idea or assume the number is so large it is not worth thinking about.

The actual answer depends on your lifestyle and expenses, not on some universal number. Here is how to figure out your personal retirement number – and what it means for how you invest today.

The 4% Rule Explained Simply

The 25x rule comes from research known as the “4% rule.” It suggests that if you withdraw 4% of your retirement savings per year, your money should last at least 30 years with a historically typical investment portfolio.

If you have $1 million saved and withdraw 4% per year, that is $40,000. If you need $50,000 per year to live, you need $1.25 million. If you only need $30,000 per year (perhaps because Social Security covers part of your expenses), you need $750,000.

This is a starting point, not an exact calculation. Your actual number depends on when you retire, what returns your investments earn, and how long you live. But it gives you a reasonable target to work toward.

How to Estimate Your Retirement Expenses

Start with what you spend today. Add up your monthly bills, food, transportation, healthcare, and personal spending. That is your current annual expense number.

Then adjust for retirement:

• You will likely not have a mortgage payment if your home is paid off
• You will not be contributing to retirement accounts anymore
• Work-related expenses (commuting, work clothes, lunches) go away
• Healthcare costs typically increase significantly
• You may travel or pursue hobbies more actively

For most people, retirement expenses end up somewhere between 70-90% of their pre-retirement spending. Use 80% as a reasonable estimate if you are not sure.

Real Numbers for Hourly Workers

Let us run through a realistic scenario. Say you currently earn $20/hour working 40 hours a week – about $41,600 per year. After taxes and work expenses, you take home and spend roughly $35,000 per year.

In retirement, you estimate needing about $28,000 per year (80% of current spending). Social Security might cover $12,000-$15,000 per year based on your work history. That means you need your savings to generate $13,000-$16,000 per year.

Using the 25x rule: $15,000 x 25 = $375,000 needed in retirement savings.

That is a very different number from the “you need $1 million” messaging that makes most people give up before they start. For many hourly workers, a realistic retirement target is $300,000-$600,000 – achievable with consistent investing over a working lifetime.

How to Get There

The math is straightforward once you have your target. If you need $400,000 and have 30 years until retirement, you need to save and invest approximately $350-400 per month at a 7% average annual return.

If you have 20 years: approximately $800 per month. If you have 40 years: approximately $175 per month.

Time is the most powerful variable. Every year you start earlier dramatically reduces how much you need to set aside each month. This is why compound interest matters so much, and why starting at 25 is so much more powerful than starting at 35.

Use Our Roth IRA Calculator

The best way to see your personal numbers is to run them. Our Roth IRA growth calculator lets you plug in your current savings, monthly contribution, and years to retirement to see exactly what you will have. Try different scenarios – starting earlier, contributing more, different return rates.

Seeing the numbers move in real time makes the goal feel concrete instead of abstract.

The Bottom Line

You do not need a million dollars to retire if your lifestyle does not require a million dollars of annual income. Figure out what you actually spend, estimate what you will need in retirement, subtract what Social Security will cover, and use the 25x rule to get your target number.

Then start investing toward that number – consistently, automatically, in a tax-advantaged account like a Roth IRA. The earlier you start, the smaller each monthly contribution needs to be. Start now.
