Cash break-even is the sales level that covers cash operating costs before collection timing and other cash movements. Work through the cost split, the formula and a bridge from operating break-even to the bank balance.
Break even cash flow, used here as operating cash break-even, is the sales level that covers cash operating costs after excluding noncash charges. Divide fixed cash operating costs by the contribution margin ratio. The result is a sales threshold; collection timing and payments outside operating costs still determine what happens to the bank balance.
Cash contribution per unit = Selling price per unit − Variable cash operating cost per unit
Cash contribution margin ratio = Cash contribution per unit / Selling price per unit
Cash break-even units = Fixed cash operating costs / Cash contribution per unit
Cash break-even revenue = Fixed cash operating costs / Cash contribution margin ratio
The SBA's break-even guidance gives the underlying fixed-cost and contribution formulas. The cash operating version uses cash costs within a stated operating scope rather than including every accounting expense.
Here the scope is operations before interest and income taxes. Fixed cash costs include the cash portion of salaries, rent and other operating overhead. Variable cash costs are the costs that change with units sold. Depreciation and amortization stay outside both groups. If a production-cost allocation includes depreciation, remove it from the variable cost calculation as well.
This is different from saying every expense excluded from the formula can be ignored. Equipment must eventually be paid for. The SEC's financial statement guide explains that depreciation is a noncash adjustment in operating cash flow, while purchases of machinery use cash in investing activities. Keep the operating threshold and the full cash schedule separate.
Use a monthly sales register and operating ledger with account, amount, cost behavior and cash/noncash labels. Keep the unit count, net selling price and variable costs on the same product and period basis. Returns, credits and discounts reduce the price actually earned.
The controller should review the labels before anyone calculates the threshold. A ledger account called manufacturing overhead can contain fixed cash rent, variable power and depreciation. Its account name does not establish its cash behavior.
A US components manufacturer uses the following monthly assumptions. Salaries are fixed within its current production capacity; commissions and shipping vary with units. The utility line represents only the fixed base charge.
| Fixed operating cost | Monthly amount (USD) | Treatment |
|---|---|---|
| Salaried operating staff | 110,000 | Fixed cash |
| Facility rent | 30,000 | Fixed cash |
| Insurance | 10,000 | Fixed cash |
| Operating subscriptions | 20,000 | Fixed cash |
| Utility base charges | 10,000 | Fixed cash |
| Fixed cash subtotal | 180,000 | Cash break-even numerator |
| Depreciation | 30,000 | Noncash |
| Amortization | 10,000 | Noncash |
| Fixed accounting cost total | 220,000 | Accounting comparison |
The sales and variable-cost assumptions are:
| Per-unit input | Amount (USD) |
|---|---|
| Net selling price | 250 |
| Materials | 100 |
| Variable outbound freight | 20 |
| Sales commission | 30 |
| Variable cash cost | 150 |
| Cash contribution | 100 |
The $100 contribution is $250 − $150. Dividing $100 by $250 gives a 40% contribution margin. These are operating assumptions, not a claim that materials purchases and customer receipts necessarily occur in the sales month.
Divide fixed cash operating costs of $180,000 by the 40% contribution margin. Cash break-even revenue is $450,000. At $250 per unit, that is 1,800 units.
| Step | Calculation | Result (units) | Result (USD) |
|---|---|---|---|
| Cash break-even units | 180,000 / 100 | 1,800 | |
| Cash break-even revenue | 180,000 / 40% | 450,000 | |
| Variable cash operating cost | 1,800 × 150 | 270,000 | |
| Contribution at break-even | 450,000 − 270,000 | 180,000 | |
| Less fixed cash operating costs | 180,000 − 180,000 | 0 | |
| Accounting operating result | 0 − 30,000 − 10,000 | −40,000 |
The proof is the operating identity:
Revenue − Variable cash operating costs − Fixed cash operating costs = 0
Here, $450,000 − $270,000 − $180,000 = $0. Reconcile the fixed cash subtotal to the labeled ledger rows and the variable cost to units multiplied by the approved cost assumptions. A zero in the last formula is not enough if the inputs omit a cost.
For comparison, accounting break-even uses $220,000 of fixed costs. At the same $100 contribution, it requires 2,200 units and $550,000 of revenue. Cash operating break-even is lower because it excludes the $40,000 of noncash charges, while accounting operating profit at that sales level remains negative.
All amounts and unit counts in this example are exact. With fractional break-even units, round the unit target up to the next whole sale and recompute revenue from that rounded quantity.
Suppose the manufacturer makes exactly the break-even sales above. Opening trade receivables are $100,000, but customer collections during the month are only $400,000.
| Receivables bridge | Amount (USD) |
|---|---|
| Opening trade receivables | 100,000 |
| Add credit sales | 450,000 |
| Less customer collections | −400,000 |
| Closing trade receivables | 150,000 |
| Increase in receivables | 50,000 |
Assume no inventory change or supplier-payment deferral, so the operating cash costs are paid in the month. The company also makes the capital and principal payments below; there are no other movements in this simplified example.
| Bank cash bridge | Amount (USD) |
|---|---|
| Customer collections | 400,000 |
| Variable operating payments | −270,000 |
| Fixed operating payments | −180,000 |
| Operating cash movement | −50,000 |
| Equipment payment | −25,000 |
| Debt principal payment | −15,000 |
| Total cash movement | −90,000 |
| Opening bank cash | 160,000 |
| Closing bank cash | 70,000 |
The operating shortfall equals the $50,000 increase in receivables. Then $160,000 − $50,000 − $25,000 − $15,000 = $70,000. A business can meet its sales threshold and still need funding because sales contribution and cash availability answer different questions.

Accounting break-even covers the expenses included in accounting profit, including depreciation and amortization. Cash operating break-even excludes those noncash charges. Use the same operating scope for both calculations, then show interest, taxes, capital purchases and debt principal separately when assessing actual funding needs.
Yes. Invoiced sales may cover cash operating costs while customers have not yet paid. Inventory purchases, debt repayments or equipment purchases can also use cash outside the operating break-even calculation. A dated receipts-and-payments schedule shows whether the company can meet those obligations.
There is no finite positive sales volume that covers positive fixed costs under those assumptions. Each additional sale contributes nothing, or consumes more than its selling price in variable costs. Review pricing, variable cost and sales mix before using a break-even target.
