## Content

**Intro:** Before sending a price increase letter, customer service and sales need to know how many customers or units they can afford to lose. The breakeven is lower than most people expect on thin margins and higher on rich ones. This tool calculates it and shows the profit change.

**Sections:**

#### How to use it

**Body:** Enter annual revenue and gross margin at current prices, the proposed percentage increase and the volume loss you expect. The breakeven shows the volume loss that leaves gross profit unchanged. The change in gross profit shows what happens at your expected loss. Use the slider to test different increases, and the chart to see how the profit change responds across a range of increases.

#### The formula

**Body:** With price p, unit cost c and margin g as a share of price, a price increase of i raises unit margin from g to g plus i, measured against the old price. Gross profit stays level when the retained volume times the new unit margin equals the old volume times the old unit margin. That gives breakeven loss equal to i divided by g plus i. A 4 percent increase at 32 percent margin breaks even at about 11.1 percent volume loss.

**Bullets:**

- Thin margins make a price increase more powerful
- Breakeven is a ceiling on loss, not a forecast
- Fixed costs mean real profit falls faster than this view shows

#### Common mistakes

**Body:** The classic error is treating the increase as a profit gain without modeling any loss at all. The opposite error is assuming the whole book will react the same way. Segment customers by alternatives available and price sensitivity, and run the calculator for each segment. Also remember that a customer who stays but buys less is volume loss, and that contract customers may be locked until renewal.

**Cta:** Netray can pull order history from your ERP to show which customers and part families have the least exposure to a price change before you send the letter.

**Faq:**

#### Why does a small increase allow large volume loss?

**Answer:** Because each remaining unit earns more, and the margin base is small. On a 20 percent margin, a 5 percent increase breaks even only at a 20 percent loss, so volume risk is lower than it feels.

#### Does this include fixed costs?

**Answer:** No. If fixed costs do not fall when volume falls, actual profit decline will be larger. Use this as the favorable bound.

#### Is margin measured on price or cost?

**Answer:** On price, as gross profit divided by revenue. Do not enter a markup percentage.

#### How do I estimate expected loss?

**Answer:** Use past increases, customer concentration, and how easily each customer can switch. Treat it as a range and test several values.
