What Is Sell-Through Rate?

Sell-through rate measures how quickly items are actually selling compared to how many are currently listed.

Sell-through rate = Items Sold ÷ Items Active

If there are:

  • 100 active listings
  • 40 sold listings (last 90 days)

Your sell-through rate is 40%.

That means nearly half of available inventory is turning over every 90 days.

Price tells you what could happen.
Sell-through tells you what is happening.

TL;DR

  • Sell-through measures velocity, not price.
  • 30–50% is typically strong for DVDs.
  • Under 10% means oversupply risk.
  • Always check demand before buying inventory.

Why most resellers get this wrong

Many beginners focus on:

  • Highest sold price
  • “Rare” keywords
  • Emotional attachment to titles
  • Outlier listings

They ignore velocity.

And velocity equals cash flow.

A $15 DVD with strong sell-through is usually better than a $25 DVD that barely moves.


Real example

Healthy example:
120 active / 48 sold (90 days) = 40%

Slow example:
600 active / 20 sold (90 days) = 3%

A high price means nothing if supply overwhelms demand.

Slow inventory kills profit. High price does not matter if it never moves.

What is a “good” sell-through rate?

For DVDs in 2026:

  • 30–50% = Strong demand
  • 15–30% = Acceptable (if margin works)
  • Under 10% = Risky
  • Under 5% = Avoid unless special case

This varies by niche and category, but velocity is always the deciding factor.


Why sell-through matters more in 2026

Streaming has created oversupply in mainstream titles.

The gap between:

  • What sells
  • And what sits

Is wider than ever.

Understanding sell-through allows you to filter noise and focus only on inventory that turns.

If you want to apply this properly, learn how to
check demand before you buy.
