How Much Should I Save for Retirement?

"How much do I need to retire?" is one of the most common — and most intimidating — money questions. The good news is that a few simple rules can turn a vague worry into a concrete target you can actually plan around.

Start with your annual expenses

Your retirement number depends far more on what you spend than on what you earn. Begin by estimating your annual expenses in retirement. Many costs (commuting, mortgage, raising children) often fall, while others (healthcare, travel) may rise.

The 25x rule

A widely used guideline is to save 25 times your expected annual expenses. If you expect to spend $40,000 a year, that points to a target of about $1,000,000. This rule is the flip side of the famous "4% rule."

The 4% rule

The 4% rule suggests that you can withdraw 4% of your savings in your first year of retirement, then adjust that amount for inflation each year, with a low risk of running out over a 30-year retirement. Four percent of $1,000,000 is $40,000 — which is why 25x your expenses is the matching savings target.

Why starting early matters so much

The single biggest factor in retirement saving isn't how much you earn — it's time. Thanks to compound growth, money invested in your twenties has decades to multiply. Someone who starts at 25 can often end up with far more than someone who starts at 35 and contributes the same amount, simply because of those extra years of compounding.

A simple savings-rate benchmark

• Saving 10% of your income is a reasonable starting point if you begin in your twenties.
• Starting later usually means saving 15–20% or more to catch up.
• Always capture any employer retirement match first — it is free money and an instant 100% return on those dollars.

Work backward from your goal

Once you have a target number and a timeline, you can work backward to find the monthly amount you need to save. Small, consistent contributions — increased a little each year as your income grows — add up to a surprisingly large nest egg over time.

Don't forget inflation

A dollar today will not buy as much in 30 years. When you set your retirement target, remember that your future expenses will be higher than today's in nominal terms. Building in a realistic inflation assumption keeps your plan grounded.

The exact number is personal, but the path is the same for everyone: estimate your expenses, set a target, start early, capture your match, and let compounding do the heavy lifting.
