Musical Instrument Store Profit Tracker

Musical Instrument Store Profit Tracker Excel — products and pricing, a daily sales log, stock and inventory with low-stock flags, and a monthly P and L dashboard. Know what every product actually earns, what is actually in stock — and whether the month actually made money.

Built for music store and instrument shop owners who need to know, product by product, what a unit really earns after cost — and how much cash is sitting on the shelf — without accounting software. If dead stock and shrinkage are quietly eating the month, this workbook shows both in plain numbers.

WHAT'S INCLUDED (6 sheets):

- Products and Pricing — product, category, unit price, unit cost, margin per unit, units sold, revenue, cost of goods, and gross profit for every product. Change a price and the margin and totals update.

- Daily Sales Log — date, product, quantity, unit price, unit cost, amount, cost of goods, and channel for every sale. Unit price and unit cost are pulled from sheet 1 by formula.

- Stock and Inventory — opening stock, stock received, units sold, shrinkage and write-offs, closing stock, reorder point, stock value, and a status flag that reads LOW - REORDER or OUT OF STOCK by formula.

- Monthly P and L — revenue, cost of goods, rent, staff, utilities, marketing, insurance, supplies and other expenses by month, Jan-Dec, with net profit and margin. Revenue and cost of goods are formulas from the Sales Log.

- Dashboard — total revenue, units, transactions, average sale, cost of goods, gross profit and margin, expenses, net profit and margin, stock value, low-stock and out-of-stock counts, shrinkage cost, dead stock value, best and weakest products, revenue by product, costs by category, and units by product.

EXAMPLE DATA (October 2026 — replace with your own numbers):

- 12 products; 425 units sold in 18 logged sales; total revenue 24,430; cost of goods 12,662.5; gross profit 11,767.5; gross margin 48.2 percent

- Operating expenses 4,905 (rent 1,850, staff 2,100, utilities 230, marketing 200, insurance 220, supplies 170, other 135); total expenses 17,567.5; net profit 6,862.5; net margin 28.1 percent

- Stock: opening 251, received 281, shrinkage 8 units costing 111, closing 99 units worth 3,436.5 at cost; 10 low-stock flags, 0 out of stock

- Best product by revenue: Electric Guitars, 3,420. Best margin per unit: Professional Saxophone, 270. Best seller by units: Strings and Accessories, 220 units

- Dead stock: Professional Saxophone sold nothing in October and holds 1,180 of stock value. Average sale 1,357.22; average revenue per product 2,035.83

- Honest tension in the example: The professional saxophone has not sold and 1,180 of cost is tied up in one instrument in the locked case, and the saxophone carries a 270.00 margin on a 1,180.00 cost, the weakest return on cost among the high-ticket instruments. Strings, reeds and small accessories shrinkage took 8 units in october.

HOW IT WORKS:

1. Download the Excel file instantly after purchase.

2. On sheet 1, enter each product, category, unit price, unit cost, and units sold. Margin per unit, revenue, cost of goods, and gross profit fill in by formula.

3. On sheet 2, add a row per sale: date, product (spelled exactly as on sheet 1), quantity, and channel. Price, cost, amount and cost of goods fill in by formula.

4. On sheet 3, enter opening stock, stock received, shrinkage and the reorder point for each product. Closing stock, stock value and the low-stock flag fill in by formula.

5. On sheet 4, enter rent, staff, utilities, marketing, insurance, supplies and other expenses each month, then check gross margin, stock value and net profit on the Dashboard.

HOW THE NUMBERS WORK:

Margin per unit is unit price minus unit cost. Revenue is price times units sold. Closing stock is opening stock plus stock received, minus units sold, minus shrinkage. Stock value is closing stock times unit cost. Net profit is revenue minus cost of goods and rent, staff, utilities, marketing, insurance, supplies and other expenses — before the owner's own pay, which comes out of profit as drawings.
