Use the sell-through rate to evaluate inventory performance, optimize stock levels, and identify slow-moving products.

Formula

Sell-Through Rate:

Sell-Through Rate = (Units Sold / Units Received) × 100%

Units Remaining:

Units Remaining = Units Received - Units Sold

Example 1: High Sell-Through

Units Received: 1,000, Units Sold: 800

Sell-Through Rate: (800 / 1,000) × 100% = 80%

Units Remaining: 1,000 - 800 = 200

✅ Excellent sell-through rate

Example 2: Low Sell-Through

Units Received: 1,000, Units Sold: 400

Sell-Through Rate: (400 / 1,000) × 100% = 40%

Units Remaining: 1,000 - 400 = 600

⚠️ Low sell-through - may need markdowns

Frequently Asked Questions

What's a good sell-through rate?

Good sell-through rates vary by industry and product type. Generally, 60-80% is considered good for most retail products. Fashion/seasonal items may have different expectations. Higher sell-through means better inventory efficiency, but 100% isn't always ideal - you may want some buffer stock.

How do I improve sell-through rate?

Improve sell-through by: better product selection, accurate demand forecasting, competitive pricing, effective promotions, better merchandising, improved marketing, customer service, and inventory optimization. Also consider markdowns for slow-moving items to free up capital.

Should I calculate sell-through by product or overall?

Calculate both! Overall sell-through shows general performance, but product-level sell-through identifies winners and losers. Calculate by product, category, brand, or SKU to identify which items need attention. This helps with purchasing, pricing, and promotion decisions.

How does sell-through relate to inventory turnover?

Sell-through rate and inventory turnover are related but different. Sell-through shows percentage sold in a period, while turnover shows how many times inventory is replaced. High sell-through typically means high turnover, but turnover also depends on how quickly you restock.

What if my sell-through rate is too high?

Very high sell-through (90%+) may indicate understocking - you're missing sales opportunities. Consider increasing inventory levels to capture more sales. However, balance with risk of overstocking. Use sales forecasting to optimize inventory levels.

How often should I calculate sell-through rate?

Calculate regularly - weekly, monthly, or quarterly depending on your business. More frequent calculation (weekly) helps catch issues early. Monthly is common for most retailers. Quarterly works for slower-moving items. Regular tracking helps identify trends and make timely decisions.
