## Content

**Intro:** Before announcing a price increase, it helps to know how much volume you can lose and still come out ahead. This calculator gives that breakeven and compares it with your own estimate of the loss.

**Sections:**

#### How to use the calculator

**Body:** Enter the current unit price, the variable cost per unit and annual volume. Set the proposed percentage increase and your honest estimate of volume lost because of it. The primary results are the breakeven volume loss, which is the cushion you have, and the change in annual contribution at your expected loss. Sweep the increase on the chart to see how the cushion grows with larger increases.

**Bullets:**

- Use variable cost only, so the contribution margin is correct
- Run it by product family; thin-margin lines have less cushion
- Be conservative about expected loss for commodity parts
- Compare with a smaller increase to see the trade-off

#### The formula

**Body:** Contribution per unit is price minus variable cost. After an increase of p percent, new contribution is old contribution plus price times p. Total contribution stays equal when volume falls to old contribution divided by new contribution. So the breakeven loss is (new CM - old CM) / new CM. For example, a price of 100, cost of 62 and a 5 percent increase gives new CM of 43 against 38, so the breakeven loss is 5 / 43, about 11.6 percent.

#### Reading the result

**Body:** A high breakeven loss means the increase is hard to lose money on. A product with a 20 percent contribution margin is much more exposed than one at 50 percent. If your expected loss is well below the breakeven, the increase is likely worth it. If it is close, consider phasing the increase, targeting only the least price-sensitive customers or pairing it with value-added service.

#### Common mistakes

**Body:** Using gross margin instead of contribution margin understates the cushion for high-fixed-cost plants, and ignoring fixed costs entirely overstates it if volume loss would strand capacity. Also remember that losing a customer often means losing other products too. Treat this as a first check, then layer in customer-specific judgment.

**Cta:** If you want this run across every SKU and customer, Netray can help pull price, standard cost and volume from your ERP to model it, read-only.

**Faq:**

#### How do you calculate breakeven volume for a price increase?

**Answer:** Divide the gain in contribution per unit by the new contribution per unit. The result is the percentage of volume you can lose before total contribution falls below today's level. Multiply by annual units to see the unit equivalent.

#### Should I use gross margin or contribution margin?

**Answer:** Use contribution margin, price minus variable cost. Fixed costs do not change with a modest volume shift, so including them distorts the result. Use standard cost with caution, because it often embeds fixed overhead.

#### How do I estimate expected volume loss?

**Answer:** Use history from past increases, customer feedback, and how easily they can switch. Commodity items with many alternatives lose more. Engineered parts with qualification costs lose less. When uncertain, test a range around your best guess.

#### Does a bigger increase always make sense?

**Answer:** No. Larger increases raise the breakeven cushion but also tend to raise expected losses. The calculator shows the cushion; your judgment supplies the loss. Test a few increase levels and compare resulting profit.
