The Working Capital Formula: Run Your Numbers in 10 Minutes
Working capital = current assets − current liabilities. Simple — and almost useless until you know the three ratios behind it, what "good" looks like for your industry, and what to do when the number comes back negative.
Key Takeaways
- The formula is one line: working capital = current assets − current liabilities. The insight is in the three ratios built on top of it.
- The working capital ratio (assets ÷ liabilities) is the health score: 1.2–2.0 is the healthy band for most operators.
- The cash conversion cycle explains why the number is what it is — and it is the lever you can actually pull.
- Negative working capital has exactly four fixes, and only one of them is funding.

The formula, with a real example
Working capital = current assets − current liabilities
Current assets — converts to cash within 12 months: cash in the bank, accounts receivable you will actually collect, inventory at what it truly sells for, prepaid expenses.
Current liabilities — due within 12 months: accounts payable, credit card balances, accrued payroll and taxes, the next 12 months of payments on any debt or advance.
A landscaping company, mid-season:
| Current assets | Current liabilities | ||
|---|---|---|---|
| Cash | $18,000 | Accounts payable | $18,000 |
| Receivables (net 30s) | $32,000 | Credit cards | $9,000 |
| Materials inventory | $6,000 | Equipment loan (12 mo) | $14,000 |
| Accrued payroll + taxes | $6,000 | ||
| Total | $56,000 | Total | $47,000 |
Working capital: $9,000. Ratio: 1.19. Positive — but thin: one big receivable paying late turns this healthy-looking business negative for a month. Which is exactly why the raw number is not enough.
The three ratios that make the number useful
1. Working capital ratio = current assets ÷ current liabilities. The benchmark band:
| Ratio | Reading |
|---|---|
| Below 1.0 | Obligations exceed liquid resources — act now |
| 1.0–1.2 | Surviving, no shock absorber |
| 1.2–2.0 | Healthy for most small businesses |
| Above 2.5 | Often lazy cash or bloated inventory |
2. Quick ratio = (current assets − inventory) ÷ current liabilities. Strips out the asset that is hardest to turn into cash on demand. Retailers and restaurants should watch this one — a 1.8 working capital ratio built on unsold inventory is a 0.9 in real life.
3. Cash conversion cycle = days inventory sits + days receivables take to collect − days you take to pay suppliers. This is the why behind your working capital. A contractor who buys materials on day 1, finishes on day 30, and collects on net-30 terms on day 60 is financing 60 days of every job out of pocket — the classic net-30 bridge problem.
What "good" looks like by industry
Working capital norms differ wildly by model — judge yours against its own kind:
- Restaurants and food service: thin (1.0–1.5) and structurally fine — sales are cash, suppliers extend terms. The restaurant cash-flow playbook.
- Contractors and trades: need fat ratios (1.5–2.5) because receivables dominate the asset side and arrive late.
- Retail and e-commerce: watch the quick ratio; inventory timing is the whole game.
- Trucking and logistics: fuel is daily, brokers pay in 30–45 — the gap is permanent and must be financed deliberately. The trucking playbook.
Negative working capital: the four fixes
- Collect faster. Deposits upfront, net-15 instead of net-30, card-on-file, late fees enforced. Cheapest fix on the menu.
- Pay slower — deliberately. Negotiate supplier terms before you are late, never after.
- Convert dead inventory to cash. A 20% markdown that turns stale stock into cash this month usually beats holding for full price in a quarter.
- Bridge the gap with capital — when the gap is timing, not losses. If receivables are real and the model is profitable, a working capital advance converts future collections into operating cash now. That is precisely what Quickie is for: $1,000–$25,000 against your deposits, soft pull, decision in minutes, every number disclosed. If the gap is losses, funding delays the reckoning and adds cost — the honest test is here.
The ten-minute drill
- Pull the balance sheet (or just your bank, AR, and card balances) and total current assets and current liabilities honestly — inventory at what it sells for, receivables you will actually collect.
- Compute working capital and the ratio. Below 1.2: continue this drill today.
- Compute the quick ratio if inventory is a big number.
- Sketch your cash conversion cycle: days to sell + days to collect − days to pay.
- Pick the fix that matches the cause — collections, terms, inventory, or a right-sized bridge.
Bottom line
The working capital formula takes thirty seconds; knowing what your number means takes the three ratios; changing it takes one of exactly four levers. Run the drill quarterly, benchmark against your own industry, and when the gap is timing — receivables and seasonality, not losses — bridge it deliberately with capital sized to your deposits, with every number on the table first.

Common questions
What is the working capital formula?
Working capital = current assets − current liabilities. Current assets are cash, receivables, and inventory converting to cash within a year; current liabilities are payables, credit card balances, and debt payments due within a year. A positive result means short-term resources cover short-term obligations.
What is a good working capital ratio?
Working capital ratio = current assets ÷ current liabilities. Between 1.2 and 2.0 is healthy for most small businesses. Below 1.0 means obligations exceed liquid resources; above 2.5–3.0 often means idle cash or bloated inventory that could be working harder.
What does negative working capital mean?
Current liabilities exceed current assets — the business cannot cover the next 12 months of obligations from resources on hand. For most small businesses it signals cash-flow stress, though some models (fast-turn retail, subscriptions collecting upfront) run structurally negative on purpose.
Can you get a loan for working capital?
Yes — working capital funding is one of the most common uses of small-business financing. Options include bank lines of credit, online term loans, and revenue-based advances like Quickie that fund $1,000–$25,000 against bank deposits with a soft pull, built for exactly this gap.
