Where people go wrong with business finance numbers
Margin and markup are confused constantly: a 50% markup gives a 33% margin, and pricing from the wrong one loses money. Ratios also need context, since a good current ratio in one industry is poor in another. Valuation multiples and discounted cash flow are only as good as the assumptions, so run them at several cases. Cash flow, not profit, is what pays the bills. Cash pays bills. Profit does not.

Definitions
Business Finance terms
- Break-even point : glossary term
- The volume at which total revenue equals total costs. It moves whenever the cost structure changes. Treat it as a range, not a point: fixed costs are only fixed within a capacity band.
- Burn rate : glossary term
- The rate at which an organization consumes cash, often measured monthly.
- Cash conversion cycle : glossary term
- Inventory days plus receivable days minus payable days.
- Contribution margin : glossary term
- Revenue remaining after variable costs, available to cover fixed costs and profit.
- Current ratio : glossary term
- Current assets divided by current liabilities.
- Discount rate : glossary term
- The rate used to convert future cash flows into present value.
- Enterprise value : glossary term
- A business value measure representing operating assets before allocating value between debt and equity.
- Fixed cost : glossary term
- A cost that does not vary with output within a given capacity range. Cross that range and it steps up.
- Gross margin : glossary term
- Revenue minus cost of goods sold, divided by revenue.
- Markup : glossary term
- Selling price minus cost, divided by cost.

Common business finance questions
How do I price a new product or service?
Start from the margin you need instead of from a markup on cost, because the two are computed on different bases and confusing them consistently underprices. Then check the price against what the market will bear and against your break-even volume. A price that is theoretically correct and commercially unsellable is not a price.
When should a business raise outside capital?
When the capital produces more value than the ownership or interest it costs, and when the business can survive the raise taking longer than planned. Raising to fund a proven, repeatable use of money is very different from raising to postpone a decision about whether the model works.
What is the difference between profit and cash flow?
Profit is recognised when revenue is earned and expenses incurred. Cash flow is when money actually moves. A business can be profitable and unable to pay wages because receivables are slow, inventory absorbs cash, or growth consumes working capital faster than operations generate it.
How do I calculate my break-even point?
Divide fixed costs by contribution margin per unit. The answer depends heavily on how costs are classified, and fixed costs are only fixed within a capacity range, so treat break-even as a range, not a point and re-run it when the cost structure changes.
What is a healthy profit margin?
It varies enormously by sector. So a figure meaningful in one industry is not in another. More informative than the level is the trend over time and the comparison to peers using the same definitions, since classification choices change every ratio downstream.
How much runway should a business keep?
Enough to reach the next milestone plus a margin for it taking longer than planned. A simple calculation divides unrestricted cash by net burn, but burn rarely stays constant: hiring, seasonality, tax payments and capital purchases all move it. So a forecast beats a division.
Why does growth make my cash position worse?
Because with a positive cash conversion cycle each additional sale must be funded from paying for inputs until collecting revenue. More sales means more gaps funded at once, which is why profitable growing businesses need working capital.
Which financial metrics should a small business track monthly?
Gross margin, operating margin, cash balance and runway, receivable ageing, and the cash conversion cycle. The specific set matters less than reviewing the same definitions every month, because a ratio only means something in comparison.
Should I raise prices or cut costs?
A price rise flows almost entirely to profit, while a cost cut of the same amount does too but is usually harder to find repeatedly. The constraint on pricing is demand. That is why testing a rise on new customers first is lower risk than an across-the-board change.
Why should I decide the sample size before an A/B test?
Stopping the moment a result looks significant raises the chance of a false positive well above the stated p-value. Fixing the sample size or the stopping rule in advance keeps the test honest.
What does OEE measure?
Overall equipment effectiveness multiplies availability, performance and quality to show how much of the possible output a machine really delivers. It shows which of the three losses is the biggest.
How do I set a safety stock level?
Pick a service level, measure the variation in daily demand and use the lead time. Higher service levels and longer lead times need more stock, and variation matters most.
How do I know if my prices are too low?
Compare each price with the full cost of a unit, including overhead and your own time. Steady sales with a thin or shrinking margin point to prices that are too low, and a small test increase shows how demand responds.
Why does working capital matter to a small business?
It is the cash tied up between paying suppliers and collecting from customers. A profitable business can still run short of cash if the gap is long, so a shorter cycle frees money without borrowing.
How does depreciation affect profit?
It spreads an asset's cost over its useful life as an expense, so reported profit is lower than cash profit in the years it is charged. The cash left the business when the asset was bought.
What is customer acquisition cost?
The sales and marketing spending in a period divided by the number of new customers won in it. Compare it with the margin a customer brings over time to see whether growth pays for itself.
Why do late-paying customers matter so much?
Late payment lengthens the cash conversion cycle, ties up working capital and can force borrowing. Tracking days sales outstanding shows the problem before it becomes a cash shortage.
Should I use a loan or my own cash to buy equipment?
Compare the loan's interest and fees with what the cash would otherwise earn or protect, and keep a reserve either way. A loan preserves cash and your own cash avoids interest, and the return on the equipment decides which is better.
How often should I review my prices and costs?
At least every quarter, and whenever a major cost changes. Costs drift upward between reviews and quietly erode margin, while prices left unchanged do not keep up.
What is a reasonable overhead rate?
It varies widely by industry, so compare it with your own history and with similar businesses. A rising rate with flat sales signals cost creep that is worth investigating.
What does a debt-to-equity ratio tell a lender?
How much of the business is funded by borrowing compared with the owners' money. Higher ratios mean more risk to the lender, and what is normal differs a great deal between industries.
How do I calculate gross margin?
Subtract the cost of goods sold from revenue and divide by revenue. A business with $1,200,000 of revenue and $700,000 of cost of goods sold has a gross margin of about 41.7 percent.
How much cash should a small business keep in reserve?
Many aim for several months of fixed costs. The right amount depends on how predictable the revenue is, how quickly customers pay and how easily the business can borrow in a shortfall.
When does it make sense to hire?
When demand consistently exceeds capacity and the added revenue covers the full cost of the hire, including payroll taxes, equipment and training. A short spike in work is often better met with overtime or contractors.
What is inventory turnover and why does it matter?
Cost of goods sold divided by average inventory. A low turnover means stock sits and ties up cash, and a very high one can mean frequent stockouts.
How do I forecast next month's cash?
Start with cash on hand, add expected collections, subtract known payments and payroll, and adjust for seasonality. Update the forecast weekly, since small timing slips add up.
What is the difference between fixed and variable costs?
Fixed costs stay the same as volume changes within a range, such as rent. Variable costs rise with each unit, such as materials. The split drives the break-even calculation.

Business Finance calculator questions
What is the difference between margin and markup?
Markup is profit as a percent of cost, while margin is profit as a percent of the selling price, so the same sale gives a lower margin.
What is a good current ratio?
Above 1 means current assets cover short-term debts, and many businesses aim for 1.5 to 2, though the norm varies by industry.
How do I calculate break-even?
Divide fixed costs by the contribution margin per unit, which gives the number of units you must sell to cover all costs.
