Break-Even Sales per Day for Shops Explained
A monthly break-even figure is useful for your accountant, but it is hard to feel at the counter on a slow Tuesday in January. Break-even sales per day turns that big number into one small target you can check every evening when you close the till. This guide shows you how to work it out, how to adjust it for busy and quiet days, and how to use it without letting it run your mood.
Key takeaways
- Break-even sales per day is the takings your shop needs on an average trading day to cover all its costs, with nothing left over.
- You need three inputs: monthly fixed costs, your average margin after variable costs, and the number of days you trade.
- A single flat daily target is a starting point. Weighting it by day of the week makes it far more realistic.
- Use the number as a weekly pattern check, not a daily verdict. One slow day means very little; four slow weeks mean a lot.
If you run a shop, you probably already know your rent, your wage bill and roughly what you sold last month. What many owners do not have is a clear answer to a simple question at closing time: "Did today pay for itself?" Without that answer, it is easy to feel fine during a busy December and then get caught out by a long, quiet stretch in the new year.
The daily break-even target fills that gap. It is not a forecast and it is not a goal you should aim to merely hit. It is a floor. Every day you trade above it builds a cushion, and every day below it eats into one. Once you can see the floor, you can plan staffing, opening hours and promotions around it.
This article is general information about shop finances, not personal financial or tax advice. If you are making big decisions, such as signing a lease or taking on a loan, go through the numbers with a qualified accountant.
What break-even sales per day actually means
Your shop has two kinds of costs. Fixed costs stay the same as sales change: rent, salaried wages, insurance, software subscriptions, loan repayments and the like. Variable costs rise with each sale: the cost of the goods you sell, card fees, packaging and delivery. Every sale first pays its own variable costs, and whatever is left over goes toward the fixed costs.
Break-even is the point where the leftover money from all your sales exactly covers the fixed costs. Below it, you lose money. Above it, you make a profit. The classic formula in units is fixed costs divided by (price minus variable cost per unit). Most shops sell hundreds of different items at different prices, though, so counting units is not practical. Instead, you work in sales value, using your average margin.
The shop-friendly version of the formula
Here is the version that works for a mixed-product shop:
- Find your margin percentage. Take your sales, subtract your variable costs, and divide the result by your sales. If $100 of sales leaves $45 after stock, card fees and bags, your margin is 45%.
- Find your monthly break-even sales. Divide monthly fixed costs by that margin percentage. With $9,000 of fixed costs and a 45% margin, you need $20,000 of sales a month.
- Divide by trading days. If you open 26 days a month, your break-even sales per day is $20,000 divided by 26, or about $770.
All the numbers above are made up for illustration. Your own figures will look different, and that is exactly why it is worth spending an hour with your own records.
Gathering your inputs without getting lost
The math is quick. The real work is getting honest inputs. Set aside an hour, pull your last 12 months of bookkeeping reports and your till reports, and work through these three areas.
Monthly fixed costs
List everything you pay whether or not a single customer walks in. Typical lines include rent or mortgage, business rates or property taxes, base wages and salaries plus employer payroll costs, insurance, utilities (most shops treat these as fixed even though they move a little with the seasons), software and point-of-sale subscriptions, loan repayments, accountant fees and a sensible amount for repairs. Annual bills should be divided by 12 so they count each month.
Do not forget to pay yourself. If you take a regular draw or salary, include it. A shop that only breaks even because the owner works for free is not really breaking even.
Your average margin
Your bookkeeping software or till system can usually show cost of goods sold against sales. Add card fees, packaging and any delivery costs you absorb. If your margin varies a lot by product category, use a weighted average based on what you actually sold, not on your list prices. Discounts and markdowns matter here: a January sale at lower prices means a lower margin, which means a higher break-even.
Trading days
Count the days you are actually open in a typical month. If you close on Mondays, or you shut for a few days over the holidays, your monthly fixed costs still have to be paid in fewer days. That pushes each day's target up.
Common mistake
Using the price tag margin instead of the real margin. If you mark goods up generously but then discount often, give staff discounts or lose stock to damage, your real margin is lower than your pricing suggests. Work from what your books show you actually earned, not what you planned to earn.
Making the daily target realistic
A flat daily figure assumes every trading day is equal. In a shop, they never are. Saturdays can be several times busier than a Tuesday, and early January rarely looks like mid-December. Comparing a quiet Tuesday against a flat average will make you feel like you are failing, even when the week is on track.
Weight the target by day of the week
Look at your till reports for the last few months and find what share of a typical week's sales lands on each day. If Saturday usually brings in 25% of the week and Tuesday brings in 10%, split your weekly break-even the same way. The total stays the same, but each day gets a fair target.
Adjust for the season
Many shops do a large share of their year in the weeks before the holidays and then go quiet in January and February. If that is your pattern, think about break-even over a full season as well as a single day. A strong December may need to carry part of a slow first quarter. Knowing your daily floor for January helps you decide early whether to trim opening hours, run an event or lean on a cash reserve.
Pro tip
Write your weighted daily targets on a small card by the till or add them to your closing checklist. When the end-of-day report prints, the person closing can circle "above" or "below" in two seconds. Small habits like this make the number part of the routine instead of a monthly surprise.
A worked example for a small gift shop
Hypothetical example
Imagine Elena, who runs a small gift and homeware shop. Her fixed costs come to $11,700 a month, including a modest salary for herself. After stock, card fees and packaging, her average margin is 50%. Her monthly break-even sales are $11,700 divided by 0.50, or $23,400. She trades six days a week, about 26 days a month, so her flat daily break-even is $23,400 divided by 26, or $900.
Her till history shows a typical week splits like this: Tuesday 10%, Wednesday 12%, Thursday 14%, Friday 18%, Saturday 30%, Sunday 16%. Her weekly break-even is $900 times 6, or $5,400. Weighted, Tuesday needs about $540 and Saturday about $1,620. A $600 Tuesday is no longer a bad day. It is a good one. All figures are made up for illustration.
Elena's example shows why weighting matters. With the flat $900 target, she would have felt behind on four days out of six, even in a perfectly healthy week. With weighted targets, she can see which days actually fall short and look for patterns, such as a Thursday that has quietly slipped for a month.
A simple daily break-even template
Copy these columns into a spreadsheet. Fill in the share of weekly sales for each day from your own till reports. The amounts below are made-up examples.
| Day | Share of weekly sales | Daily break-even target (example) | Actual sales (example) | Above or below | Note |
|---|---|---|---|---|---|
| Tuesday | 10% | $540 | $610 | Above by $70 | Rain, but steady regulars |
| Thursday | 14% | $756 | $690 | Below by $66 | Road works outside |
| Saturday | 30% | $1,620 | $1,840 | Above by $220 | Local market day |
Add a running weekly total at the bottom. The weekly line is the one to watch. Individual days will bounce around, but a week that ends below break-even several times in a row is a real signal.
What to do when you are below break-even
Every shop has weeks below the line, especially in early January. What matters is spotting a pattern early and choosing a response on purpose. There are only three levers, and it helps to think about them in this order.
Lever 1: sell more at the same margin
Look at the hours and days that fall short. Could a small event, a local partnership, a social post about new stock or a reminder to past customers bring people in on a quiet weekday? Raising the average basket also helps: better placement of add-on items near the till and staff who are comfortable suggesting a matching product can move the daily figure without extra footfall.
Lever 2: improve the margin
A small improvement in margin lowers your break-even across every single day. Review which suppliers have raised costs, which products you discount most often and whether card fees, packaging or free delivery are eating more than you thought. Even a few percentage points can make a meaningful difference to the daily target.
Lever 3: reduce fixed costs
This is often the slowest lever because rent and core wages do not change quickly. Still, check subscriptions you no longer use, whether opening hours match when customers actually come, and whether staffing on the quietest days can be adjusted fairly and within your employment obligations. If you are thinking about changing hours or contracts, check the rules where you operate and get advice first.
Pro tip
Before you cut anything, run the numbers again with the change. Shorter opening hours lower some costs, but they also reduce the days you can sell. Your break-even per day might go up, not down, even if the month gets cheaper.
Keeping the number honest over time
A break-even target is only as good as the inputs behind it. Recalculate it whenever something important changes: a rent review, a new hire, a supplier price rise, a change in your product mix or a shift in opening days. A quick check once a quarter is a sensible habit, and a fuller review at the start of the year fits naturally with your other planning.
Your daily break-even action plan
- List every monthly fixed cost, including your own pay and annual bills divided by 12
- Work out your real average margin from your books, after card fees and packaging
- Count your trading days in a typical month
- Calculate monthly break-even sales and divide by trading days
- Use your till history to weight the target by day of the week
- Add the targets to your closing routine and track a weekly total
- Review the pattern every month and recalculate each quarter
Frequently asked questions
Should I include VAT or sales tax in my daily sales figure?
Usually no. Sales tax or VAT you collect belongs to the tax authority, not to you. Compare your break-even target against sales excluding those taxes, and make sure your margin is calculated the same way so the numbers match.
How is daily break-even different from a sales target?
Break-even is the floor where you cover costs and make no profit. A sales target should sit above it and include the profit you want, plus a buffer for slow periods. Many owners set a break-even line and a separate goal line on the same sheet.
What if I sell online as well as in the shop?
You can calculate one combined target or separate ones. Online orders often carry different variable costs, such as shipping and platform fees, so their margin may differ. Splitting the channels makes it easier to see which one is really carrying the business.

The bottom line
Break-even sales per day takes a figure that usually lives in a spreadsheet and puts it at the till, where you can see it every evening. Add up your fixed costs, find your real margin, divide by your trading days and weight the result by how your week actually flows. Then watch the weekly total rather than any one day.
Spend an hour on it during a quiet morning in early January. Once you know your floor, every decision about hours, staffing and promotions in the new year gets a little easier and a lot calmer.
