Value Proposition: Instead of saying “the margin dropped,” this model provides you with a Gross Margin Bridge that explains the drop/increase: Price / Volume / Mix / Discounts / Cost — with traceable numbers.

Practical Definition: True Profit Margin Analysis during closing or performance review does not stop at (Gross Margin %).
The real scenario: management sees the margin change compared to the previous month or the same period last year. The question is not “how much?” but “why?”.
The usual problem is that the report only presents Sales and COGS, without explanation: Is the reason Price Volume Mix? Did discounts increase? Did the cost of sales rise due to supplier/shipping/inventory pricing?
This model builds the Gross Margin Bridge step by step: starting from revenue and COGS data at the (Product/Customer/Channel) level as data is available,
then breaks down the change into drivers, shows the impact of discounts on the margin, and produces a Cost of Sales Analysis linking the increase to its source.
The result: an explanation of margin variances in a single file, deliverable to the head of accounts, management, and auditors.

In 20 Seconds: What Will You Get?

• A Gross Margin Bridge file that links margin from period to period (Current vs Prior).
• Price Volume Mix analysis at the SKU/Customer/Channel level based on your data.
• Measurement of impact of discounts on margin (Discounts/Allowances/Rebates) instead of merging them into sales.
• Cost of Sales Analysis clarifies: Is the issue in Unit cost? In Mix? In shipping/expenses within COGS?
• Reconciliation proves that the analysis result = actual change in GM (Tie‑out).
• Exceptions List: Products/Customers that caused the largest variances (Top drivers).
• Ready narrative summary: Explanation of Margin Variances in concise points suitable for presentation.

CTA related to outputs: You will receive GM Bridge + PVM + Discount Impact + Cost Analysis.

Suitable For

• FP&A / Management Accounting: Explaining margin changes before performance and budget meetings.
• Head of Accounts / Month-End Owner: Preparing explanations for margin variances as part of the Closing Pack.
• Commercial Finance: Isolating the impact of discounts, price, and mix on profitability by channels and customers.

Not Suitable For

• If there is no Quantity data or any Dimension (SKU/Customer/Channel) — the analysis will revert to a limited aggregate level.
• If COGS itself is not substantiated or has significant unexplained variances — it is better to run COGS Reconciliation first and then create the margin bridge.

Without Analysis / With Profit Margin Analysis (Brief Comparison)

Before Use: 5 Symptoms That Margin is “Changing Without Explanation”

• Declining GM% despite stable apparent prices in the price list.
• Increased discounts/rebates but their impact is not clearly shown in performance analysis.
• COGS rises while Volume is stable — and you don’t know if the reason is Unit cost or Mix.
• Management asks about the reasons for the change and there is no file linking causes to numbers.
• Each team provides a different explanation (Sales says discounts, Ops says costs, Finance says mix) without a single bridge to clarify.

How Does Profit Margin Analysis Work Practically Using the Gross Margin Bridge?

The operation begins by defining a comparison period: the current month versus the previous one, or YTD versus LYTD.
Sales and COGS data (and discount items if available) are loaded at an appropriate analysis level: SKU or Customer or Channel.
The model then breaks down the change in revenue into Price Volume Mix (price/quantity/mix),
then isolates the impact of discounts on margin as a separate item so it does not get lost within “Net Sales”.
On the cost side, a Cost of Sales Analysis is constructed: Is the increase due to Unit cost? Due to mix? Due to including expenses within COGS?
Finally, a Gross Margin Bridge is produced that links GM from period to period (Tie‑out) with a list of major drivers and exceptions.

Application Method (3 Steps)

Step 1: Preparation and Report Gathering

• Sales report: Qty + Sales value (Gross/Net) by SKU/Customer/Channel.
• COGS report at the same dimensions or the closest available level.
• Discounts/Allowances/Rebates (if separate) to determine the impact of discounts.
• Define the reference period (Prior month / Budget / LY).

Step 2: Build Price‑Volume‑Mix + Isolate Discounts

• Calculate Price impact, Volume impact, and Mix impact on revenue.
• Produce a PVM table by SKU/Channel/Customer with Top drivers.
• Separate discounts from Net sales and measure their impact on GM.

Step 3: Analyze Cost of Sales + Tie‑out + Deliverable Outputs

• Analyze changes in COGS: Unit cost change vs Mix vs other cost drivers.
• Build a final Bridge: GM Prior → +/‑ drivers → GM Current (Reconciliation).
• Produce a narrative summary + exceptions list + sign‑off.

FAQ — Questions Before Purchase

Does the analysis require Quantity?

It is highly preferred because Price‑Volume‑Mix relies on quantity. Without Quantity, a total Bridge can be created but with less explanatory value.

Can it be run at the Customer or Channel level instead of SKU?

Yes, depending on the dimensions available in your data. It is best to run it from multiple perspectives when data is available.

How does it measure the impact of discounts on margin?

It separates Discounts/Allowances/Rebates as an independent item and compares them between periods to measure their impact on GM.

Does it include Cost of Sales Analysis?

Yes: it isolates changes in COGS to Unit cost/Mix/Other cost drivers based on the available data level.

Is it suitable for monthly closing only or also for annual closing?

For both; monthly for performance tracking, and annually to support explanations of variances in audit and management.

Does it recalculate COGS from the inventory equation?

No; it assumes that COGS is ready from the system. If COGS is not substantiated, it is better to use COGS Reconciliation first and then the Bridge.

Can Budget vs Actual be added?

Yes, as a comparison period (Budget) instead of Prior, provided that Sales/COGS/Discounts are available at the same dimensions.

What is the minimum data required?

Sales value + COGS for two periods. It is preferable to include Qty + Discounts to create PVM and measure the impact of discounts accurately.
