1. What you will learn
This lesson builds the outcome map and a diagnostic for retail expansion. You will learn four-wall profit, which is the profit of a single outlet before owner overhead, how to compute it for your existing shop, how to turn it into a payback for a second outlet, and how to read same-store sales as a sign of whether the first shop is healthy enough to copy.
2. The idea explained
Before copying a shop, you must know exactly what one shop earns. The measure used in retail is four-wall profit, meaning the profit an outlet makes within its own four walls: sales, minus the cost of goods, minus the costs that belong to that outlet, such as rent, wages, power and repairs. It leaves out overhead that belongs to the whole business, such as the owner's central time or head office costs, and it leaves out interest and tax. It answers a simple question: does this location, with this team, earn more than it costs to run?
Four-wall profit is the number that tells you what a second outlet might earn once it matures. If your first shop earns a four-wall profit of 10 per cent of sales, a copy that reaches similar sales would earn the same. But three cautions apply. First, the owner's own work must be counted at a fair wage, otherwise the four-wall profit is overstated. Second, a new outlet reaches maturity only after a ramp-up period, and the cash spent during ramp-up must be added to the investment. Third, the new outlet is unlikely to match the old one unless its location, team and customers are similar, and that has to be shown, not assumed.
Same-store sales is the second key number. It compares the shop's sales with the same period last year. If it is rising steadily, the shop is winning customers. If it is flat or falling while prices rise, the shop is quietly shrinking, and a second outlet would copy a weakness. The outcome map of the programme lays out what you will be able to do at the end: compute four-wall profit and payback, judge readiness with gates, choose locations and formats on evidence, plan cash to the last month of ramp-up, build the routines and controls a second outlet needs, and run a pilot and a ninety-day plan with stopping rules. It cannot promise that you will expand, and often the right outcome is to wait or to decline. Most new ventures fail, and honesty about your numbers is the first defence.
Apply it
3. How to apply it in your own business
Gather twelve months of figures for the existing shop: monthly sales, cost of goods sold, rent, wages, power, repairs and other costs that belong to the shop. Compute for each month the gross profit and the four-wall profit before your own pay. Then subtract a fair wage for the person who runs the shop, giving the four-wall profit after management.
Compute the annual figures and the four-wall profit as a percentage of sales. Note the lowest and highest months. Compare the last twelve months with the twelve before that, or if you lack data, compare this quarter with the same quarter last year, giving same-store sales growth. Consider inflation or price changes when you read the growth, since a rise driven only by prices may hide fewer bills.
Now build a first payback estimate for a copy. Take the mature four-wall profit after management, apply a cautious factor, such as two-thirds, to allow for the fact that a new place is rarely as good, and divide the total investment, including ramp-up cash, by the monthly result. Compare with your alarm line, for example thirty months. Write the outcome map: what must be true before you go further, in terms of same-store sales, four-wall profit, cash and routines. Repeat the diagnostic every quarter. It is a teaching aid, not accounting advice, and it does not promise any return.
Worked example
4. Worked example
Consider Nalini, who runs a household goods shop. Her twelve-month sales were 8,400,000 rupees, and last year's were 8,000,000. Same-store sales growth is 400,000 divided by 8,000,000, which is 5 per cent. She recalls that prices rose by about 3 per cent, so most of the growth is price, and the real rise in volume is small.
Her average month: sales 700,000, cost of goods 490,000 (a gross margin of 30 per cent, which is 210,000). Costs of the shop: rent 50,000, wages 60,000, power 10,000, other shop costs 15,000, a total of 135,000. Four-wall profit before her own pay is 210,000 minus 135,000, which is 75,000 rupees a month, or 10.7 per cent of sales. A fair wage for a manager is 30,000, so four-wall profit after management is 45,000 a month, or 6.4 per cent of sales.
She estimates the total investment for a copy, hypothetically: fit-out 300,000, deposit 150,000, opening stock 250,000, pre-opening costs 50,000, and ramp-up cash 150,000, a total of 900,000 rupees. If the copy reached her mature figure of 45,000, payback would be 900,000 divided by 45,000, which is 20 months. Applying a cautious factor of two-thirds gives 30,000 a month and a payback of 900,000 divided by 30,000, which is 30 months.
That exactly touches her alarm line of thirty months. She also sees that same-store growth in real terms is weak, which means the first shop is holding rather than winning, and that four-wall profit of 6.4 per cent leaves little room for a mistake. She concludes that the first shop should be strengthened before it is copied. Her outcome map lists: raise real volume, lift four-wall profit after management to at least 8 per cent, write the routines, and build free cash. She will run the diagnostic again in three months. All figures are hypothetical.
She shares the page with her accountant and asks whether the costs of the shop are complete.
5. Common mistakes and how to fix them
The first mistake is measuring profit before a fair wage for the manager. Subtract it to get the true four-wall figure. The second mistake is reading a price-driven sales rise as growth; separate price from volume.
The third mistake is assuming a copy will match the original. Apply a cautious factor and prove the location with a pilot. The fourth mistake is forgetting ramp-up cash in the investment; add it.
Key takeaways
6. Board summary
Four-wall profit is what an outlet earns within its own walls. Subtract a fair manager wage from the four-wall profit. Same-store sales shows whether the first shop is healthy. Payback equals total investment including ramp-up divided by cautious monthly profit. Strengthen the first shop before copying it.
