PetshopMBA · Lesson 06 · Pricing That Pays

The delivery is on the floor, the invoice says ₱700 a bag, and you need a shelf price before the shop opens. You add 25% and write ₱875 on the tag.

It feels like a 25% margin. It is a 20% margin. In Lesson 05 you saw why: adding a percentage to cost is markup, and markup always overstates what you keep.

This lesson gives you the fix, one formula that turns the margin you want into the exact price you need: Price = Landed cost ÷ (1 − Target margin).

What Is Target Margin Pricing?

Choose the result first, then find the price that gets you there.

🎯

Target margin

Decided First

The share of the selling price you want to keep as gross profit, for example 25% on dog food.

Set per category, not per mood

🚚

Landed cost

Your Starting Point

Supplier price plus your share of delivery, fees and handling, as in Lesson 03.

₱680 supplier price + ₱20 delivery share = ₱700

🏷️

Shelf price

The Result

The price that delivers your target margin, rounded up to a clean number.

₱933.33 rounded up to ₱935

The Key Insight

Pricing is not "cost plus something". It is "what price leaves me the margin I need?" Ask it that way and the formula follows.

The Target Margin Price Formula

Divide, do not multiply.

The Formula
Price
=
Landed Cost
÷
(1 − Target Margin)
CostLanded cost. What one unit really cost you to get onto your shelf.
TargetTarget margin. The margin you want, written as a decimal. 25% is 0.25, 40% is 0.40.

Why divide? If you want to keep 25% of the price, then your cost must be the other 75% of the price. So the price is cost ÷ 0.75. Multiplying by 1.25 answers a different question, which is why it falls short.

See It in Pesos: One Bag, Four Targets

Cost + 25%

Landed cost ₱700
Shelf price ₱875
Profit per bag ₱175
Margin 20.0%
Gross profit on 50 bags ₱8,750
✅

Target Margin 25%

Landed cost ₱700
Shelf price ₱935
Profit per bag ₱235
Margin 25.1%
Gross profit on 50 bags ₱11,750

On one product, selling 50 bags a month, the difference is ₱3,000 a month. Repeat the same mistake across every item in the shop and the gap can be bigger than your rent.

Pricing a Treat Jar, Step by Step

The same formula works for every product. Only the target changes.

Worked Example: A Treat Jar at a 40% Target
Supplier price per jar₱110
Delivery and fees per jar₱10
Target margin40%

Landed cost: ₱110 + ₱10 = ₱120

Divide by: 1 − 0.40 = 0.60

Price: ₱120 ÷ 0.60 = ₱200

Check: (₱200 − ₱120) ÷ ₱200 = 40%

Shelf price₱200
If the right price looks too high for your area, that is a buying or product decision to make. It is not a reason to quietly accept a thinner margin.

Three Ways Prices Drift Below Target

Each one is small. Together they add up.

⬇️

Rounding down

₱933 Becomes ₱930

A few pesos per unit feels harmless. Across hundreds of units a month, it is real money. Round up.

🧾

Supplier price only

Delivery Left Out

Pricing from the invoice price instead of landed cost puts you below target before the first sale.

⏳

Old prices

Costs Went Up

When a supplier raises prices and your tags stay the same, your margin shrinks every day you wait.

Reprice Your Shelves This Week

Start with the items you sell most.

🗂️

Set your targets

Write one target margin for each category, for example food, litter, treats and accessories.

🚚

Update landed costs

Use your latest invoices, including delivery and fees, for your top 20 items.

🧮

Run the formula

Landed cost ÷ (1 − Target margin). Round up to a clean price.

🏷️

Change the tags

Update shelf tags and your price list on the same day so they always match.

Copy this: repricing sheet

ItemLanded costTarget marginCost ÷ (1 − target)Shelf price
____₱ ________ %₱ ____₱ ____
____₱ ________ %₱ ____₱ ____
____₱ ________ %₱ ____₱ ____

Write the target as a decimal when you divide. 25% is 0.25.

A Good Price Starts With a Known Cost

The formula is only as accurate as the landed cost you put into it.

When stock comes from many suppliers, each with its own delivery fee and payment, working out the true landed cost of every item takes time. Many owners skip it, and their prices drift below target.

Key Takeaways

Lesson 06 in Five Lines
  • Price = Landed cost ÷ (1 − Target margin).
  • Adding 25% to cost gives a 20% margin, not 25%.
  • Start from landed cost, never from the supplier price alone.
  • Round up to a clean shelf price, never down.
  • Reprice whenever your costs change.

You now have a pricing rule that lands on your target every time, for every product, with one division.
