How do you calculate your savings rate?

Divide what you saved in a month by your income in the same month and multiply by 100. The two choices that change the result are which income you use (take-home or gross) and whether savings taken out of your paycheck before it arrives, like a 401(k), count. A consistent version: add pre-tax retirement contributions to both what you saved and your take-home pay. Example: $450 saved from a $3,650 paycheck plus a $300 401(k) contribution is $750 ÷ $3,950 = 19.0%.

The formula, and the two decisions inside it

Savings rate = money saved in the period ÷ income in the same period × 100

• Which income. Take-home pay is what you can actually decide about, so it is the most useful base for a personal budget. Gross income is useful for comparing with retirement rules of thumb that are stated in gross terms.
• What counts as saved. Money moved to savings or investment accounts counts. Pre-tax retirement contributions also count, but they never appear in your take-home pay, so if you count them as savings you must add them to income too, or the rate comes out too high. An employer match can be included the same way; decide once and stay with it.

The US national figure uses a third definition: the Bureau of Economic Analysis divides personal saving by disposable personal income (income after taxes). It was 3.0% in July 2026 (BEA, Personal Income and Outlays, July 2026). Because the definitions differ, compare your rate with your own earlier months, not with that number.

Worked example: one month, four answers

Alex earns $5,000 a month before tax. 6% ($300) goes into a 401(k) before tax, the employer adds a $150 match, and $3,650 arrives in the checking account. From that, Alex moves $250 to a savings account and $200 to a Roth IRA, so $450 of take-home pay is saved.

What the table tells Alex:

• The same month can be "12%" or "22%". None of the four is wrong; they answer different questions. Mixing them from month to month is what makes a savings rate useless.
• Version 1 undercounts. It ignores $300 of real saving just because it leaves the paycheck early.
• Version 2 is a good default for tracking. It counts everything you save from your own pay and uses the money you actually control as the base.

Calculate your savings rate

The cross-check: income minus spending

Transfers only show what you moved on purpose. If money piles up in checking, your real savings rate is higher; if you move money to savings and later pull it back, it is lower. Once a month, check the other way round: take-home pay − everything you spent = what you really saved. If the two numbers differ a lot, trust the second and find out where the gap comes from.

Common mistakes

• Counting a transfer you reverse later. Money moved to savings on the 1st and back on the 20th was not saved.
• Adding the 401(k) to savings but not to income. In the example that gives 750 ÷ 3,650 = 20.5% instead of 19.0%.
• Counting debt payments as saving. Paying down a credit card improves your net worth, but it is not the same as savings you can use. If you want to track it, track it as its own line.
• Judging a single month. A month with a yearly insurance bill will look terrible. Look at the average of the last three or twelve months.

Follow-up questions

What is a good savings rate? There is no single right number; it depends on your goals and how much you already have. What matters most is that it is above zero every month and rises over time. Start from your current rate and add a percentage point when you get a raise.

Should money for sinking funds count as savings? Money you set aside for a known bill, like car insurance, will be spent. Many people leave it out of the savings rate and track it separately so the rate shows long-term saving only.

Does paying extra on my mortgage count? Same logic as debt: it builds wealth, but it is not accessible. Track it separately if you want to see it.
