A freelancer’s savings rate is everything you saved over the last 12 months divided by what the business actually left you: revenue minus business expenses minus income and self-employment taxes. Count pre-tax retirement contributions (Solo 401(k), SEP IRA, HSA) as savings, and measure over a rolling 12 months rather than month by month, because one slow quarter will otherwise make your rate look like zero.
The rest of this guide walks through each piece of that formula with real numbers, including a common calculation error that inflates freelancers’ savings rates by ten points.
Why the W-2 savings rate formula breaks for freelancers #
An employee’s paycheck arrives with taxes already withheld and retirement contributions already taken out. The math is almost done for them. You get none of that. Your deposits are gross revenue, some of that money belongs to the business, a large slice belongs to the IRS, and your retirement contributions happen whenever you remember to make them.
Three things go wrong if you plug freelance numbers into an employee formula:
- Using revenue as income. A $10,000 invoice isn’t $10,000 of income. Software, contractors, equipment and insurance come off first.
- Forgetting self-employment tax. You pay both halves of Social Security and Medicare, which employees split with their employer.
- Measuring one month at a time. Freelance income is lumpy. A month where you save 70% and a month where you save nothing tell you very little on their own.
Step 1: Find your net business profit #
Start with the number on your Schedule C: gross receipts minus ordinary and necessary business expenses.
| Line | Example |
|---|---|
| Client revenue (12 months) | $120,000 |
| Software, hardware, subcontractors, insurance, fees | −$20,000 |
| Net business profit | $100,000 |
Business expenses never count as savings, even when they feel like investments. A new laptop or a course may pay off, but it doesn’t add to the money that will fund your retirement.
Step 2: Subtract the taxes you actually pay #
Self-employment tax is 15.3% (12.4% Social Security plus 2.9% Medicare) applied to 92.35% of your net earnings, per IRS Topic 554. On $100,000 of profit that’s about $14,130, and half of it is deductible when you calculate income tax. The Social Security portion stops at an annual wage cap. The Medicare portion doesn’t.
Add federal and state income tax on top. The cleanest number to use is the total you actually paid for the year, including quarterly estimates and anything due at filing. In our example, suppose that total comes to $25,000.
After-tax income = $100,000 − $25,000 = $75,000. This is the denominator you want.
Pre-tax retirement contributions are already baked in here. A Solo 401(k) deferral lowers your income tax, so your tax bill is smaller and your after-tax income is higher than it would otherwise be. You don’t need to add them back separately as long as you also count them as savings.
Step 3: Add up everything you saved #
Include every dollar that went toward future-you:
- Solo 401(k) or SEP IRA contributions (pre-tax or Roth)
- IRA contributions
- HSA contributions
- Taxable brokerage deposits
- Cash moved to savings that’s earmarked for goals, not next quarter’s tax bill
That last point matters. Money you set aside for estimated taxes is not savings. It’s a liability you haven’t paid yet.
Step 4: Divide, and watch for the double-count trap #
The formula:
Savings rate = total saved ÷ (net profit − taxes paid)
Here’s a full example. Sarah, a freelance designer, had the $100,000 profit and $25,000 tax bill above. Over the year she saved:
| Account | Amount |
|---|---|
| Solo 401(k), pre-tax | $15,000 |
| Roth IRA | $7,500 |
| Taxable brokerage | $7,500 |
| Total saved | $30,000 |
Her savings rate is $30,000 ÷ $75,000 = 40%. Her spending was $45,000, and $45,000 + $30,000 = $75,000, which confirms the math.
The trap is a formula you’ll see online: (pre-tax + post-tax savings) ÷ (take-home spending + pre-tax savings). Plug Sarah’s numbers in and you get $30,000 ÷ $60,000 = 50%. It looks rigorous, but the denominator leaves out her Roth and brokerage money, so savings appear in the top of the fraction and are missing from the bottom. Every dollar you save post-tax makes the rate look better than it is. If your spreadsheet shows a rate that seems too good, check this first.
Whichever version you use, stay consistent. Some people prefer to divide by gross profit ($100,000), which gives Sarah 30%. That’s fine as long as you compare this year to last year with the same method. We compare both approaches in gross vs. net savings rate.
How to handle irregular income: the trailing 12 months #
Monthly savings rates swing wildly for freelancers. A $2,000 month followed by a $20,000 month might show 0% and then 70%, and neither number describes your habits.
Use a trailing 12-month (TTM) figure instead:
- Keep a simple log with four columns per month: profit, taxes paid, amount saved, and spending.
- Each month, sum the last 12 rows and run the formula on the totals.
- When a new month arrives, drop the oldest one.
TTM smooths out seasonality and tells you whether your habits are improving. It also lines up with how you’ll live in retirement, where you budget by the year.
Pay yourself a salary #
The easiest way to make freelance money behave like a paycheck is to separate it:
- All client payments land in a business checking account.
- Taxes go to a separate savings bucket as soon as each invoice clears (25% to 30% is a common starting point; your accountant can refine it).
- A fixed “salary” moves to personal checking on the same day each month.
- Whatever builds up beyond a few months of salary plus taxes gets swept to retirement accounts.
Now your personal side has a steady income, and your savings rate becomes a monthly habit you can keep.
Retirement accounts that raise a freelancer’s savings rate #
Self-employed people get unusually high contribution limits. Here are the 2026 numbers from the IRS:
| Account | 2026 limit | Who it suits |
|---|---|---|
| Solo 401(k) | $24,500 employee deferral, plus an employer profit-sharing contribution, up to $72,000 total | Solo businesses that want the highest limit at moderate income |
| SEP IRA | Employer contribution only, up to the same $72,000 cap | People who want minimal paperwork |
| IRA (traditional or Roth) | $7,500, plus $1,100 if you’re 50 or older | Everyone with earned income |
| HSA | $4,400 self-only, $8,750 family | People on an HSA-eligible health plan |
A correction to a figure you’ll see everywhere: sole proprietors can’t contribute 25% of net profit as the employer. For a Schedule C business, the employer contribution works out to about 20% of net self-employment earnings after the deduction for half of SE tax. On Sarah’s $100,000, that’s roughly $18,600. The 25% figure applies to W-2 wages paid by a corporation. IRS Publication 560 has the worksheet.
The Solo 401(k) usually wins at lower incomes because the $24,500 employee deferral doesn’t depend on a percentage of profit. At $60,000 of profit, a SEP might allow about $11,000, while a Solo 401(k) allows the $24,500 deferral plus the employer piece. If you’re 50 or older, Solo 401(k) catch-ups add $8,000 in 2026, or $11,250 if you’re 60 to 63.
For a deeper look at the account choice, see traditional vs. Roth IRA for FIRE. If you’re on a high-deductible plan, the HSA’s triple tax advantage makes it one of the best accounts a freelancer can open.
Turning your savings rate into a retirement date #
A savings rate on its own is just a percentage. What you want to know is when it gets you out. At a 40% rate from zero, with a 5% real return and a 4% withdrawal rate, the math lands at roughly 22 years. At 50%, it’s closer to 17. Our savings rate and retirement date guide has the full table.
That’s the question Retire Goals is built to answer. You create a FIRE goal (or a 401(k), Roth IRA or custom goal for each account), then log contributions whenever a client pays, whether that’s $300 one week or $6,000 after a big invoice. Every entry moves the projected finish date, and a Monte Carlo outlook shows the odds you reach it rather than a single straight line. It doesn’t connect to your bank, so there’s nothing to link and nothing to sync. Your data stays on your phone, and you can export a CSV if you also keep a spreadsheet.
Frequently asked questions #
Do business expenses count toward my savings rate? #
No. Business expenses are the cost of earning your income, so subtract them before you calculate anything. Equipment that will be useful for years is still a business cost, not a personal investment.
Should I count money set aside for quarterly taxes as savings? #
No. Your tax reserve is money you owe, just not yet. Leave it out of the numerator and subtract the actual taxes paid from the denominator. Counting it would inflate your rate every quarter and then collapse it when the payment goes out.
What is a good savings rate for a self-employed person? #
Around 15% of income is the usual target for a traditional retirement at 65. People aiming for early retirement usually target 30% to 50% or more. Freelancers often need an extra cash buffer on top of that, because income can stop without notice and there’s no unemployment check or employer match to lean on.
Is a Solo 401(k) or SEP IRA better for freelancers? #
For most one-person businesses a Solo 401(k) allows larger contributions at the same income, because of the $24,500 employee deferral, and it can offer Roth contributions. A SEP IRA is simpler to open and has no annual plan filing, while a Solo 401(k) needs Form 5500-EZ once its assets pass $250,000. If you have employees, the rules change, so talk to a tax professional.
How often should I recalculate my savings rate? #
Monthly, using the trailing 12 months. That’s frequent enough to catch a spending drift early, and the 12-month window keeps one slow month from spoiling the number.
