How Much Should I Save Each Month? The 20% Rule and Beyond

Short answer: a common guideline is to save about 20% of your take-home pay each month, including money for debt repayment, emergencies and retirement. If your budget is tight, 10 to 15% is a realistic floor, and saving something is better than saving nothing. Start with an amount you can keep up, then raise it by one percentage point every few months or whenever your pay rises.

Key takeaways

• 20% of take-home pay is a benchmark, not a rule. The right number depends on your goals, debts and costs.
• Automate the transfer on payday so saving happens before spending.
• Raise your rate gradually: one extra percentage point at a time is rarely noticeable.
• Split savings by purpose: emergency fund, debt, retirement and other goals.

How much is 10%, 15% and 20% of your pay?

The 20% usually covers everything that is not spending, including extra debt payments, so you do not have to find 20% on top of your debts. The popular 50/30/20 rule splits take-home pay into needs, wants and savings, though it is a starting point that strains in high-cost cities and loosens as pay grows.

What do these amounts grow to?

At an assumed 7% annual return, saving 15% of $4,500 (that is $675 a month) for 30 years grows to about $823,480, from $243,000 paid in. At 10% ($450 a month) it grows to about $548,987, and at 20% ($900 a month) to about $1,097,974. Returns vary and are not guaranteed, but the pattern is clear: a higher rate and more time are both powerful. See how long it takes to save $1 million.

What if you cannot afford to save 20%?

1. Start smaller. $25 or $50 a month builds the habit. The first step matters more than the amount.
2. Raise it gradually. Increase by one percentage point every quarter or each time you get a raise.
3. Look for the big three. Housing, transport and food are usually most of the budget, and small cuts there beat dozens of tiny ones.
4. Save part of every raise. Committing half of any raise to savings means your lifestyle still improves while your savings rate rises.
5. Raise income. A side income is easier to save in full, since your regular costs are already covered.

Where should your savings go first?

Keep predictable irregular costs apart with sinking funds, and use specific goals to give each dollar a purpose.

How much should you save for retirement specifically?

A commonly cited guideline is about 15% of your pre-tax income, including any employer match, over a full career, though the right figure depends on when you start and what lifestyle you want. Starting later means saving more. See how much you should have in your 401(k) by age, and check where you stand with the retirement and FIRE readiness report.

What changes the right number for you?

How can you find your number in five minutes?

1. Write down your monthly take-home pay.
2. Multiply it by 10%, 15% and 20%, using the table above.
3. Check each result against your budget. Pick the highest one you can keep up for a year.
4. Set the transfer to run on payday.
5. Put a reminder in your calendar in three months to raise it by one percentage point.

How do you make saving automatic?

• Set up a transfer for payday, to a separate account, so the money never sits in your spending account.
• Increase your 401(k) contribution by one point and see whether you notice.
• Name the accounts after the goals, such as "House deposit".
• Review once a quarter and raise the amount if you can.
