Understanding Sell-Through Rate

  • Units Sold: The total number of units sold during your selected time period.
  • Beginning Inventory: The number of units available at the start of your time period.
  • Time Period: The timeframe you're measuring (weekly, monthly, quarterly, etc.).

Benefits of Tracking Sell-Through Rate

Monitoring your sell-through rate provides valuable insights for your retail business:

  • Identify fast and slow-moving products
  • Optimize inventory purchasing decisions
  • Evaluate effectiveness of marketing campaigns
  • Improve cash flow by reducing excess inventory
  • Make data-driven pricing and promotion decisions

Pro Tip

A healthy sell-through rate varies by industry, but generally 60-80% monthly is considered good for most retail businesses. Lower rates may indicate overbuying or weak demand, while extremely high rates could mean you're missing sales opportunities.
