# See what a price change does to your profit before you make it

> Slide your price up 10 percent and see how many customers you could lose and still earn what you do today.

## How do I test a price increase before I raise my prices?

Build a what-if model from your own sales and cost numbers, then move a price slider and watch profit and break-even change. Gemini can turn a spreadsheet or receipts into an interactive model, and as of October 2026 that's part of its new small business tools. Claude and ChatGPT can build a similar model from an attached file. If you sell services, model the number of clients. If you sell products, model units sold and cost per item.

## The prompt

Fill in the parts in [square brackets], or leave them and the AI will ask you for them.

```text
I run [YOUR BUSINESS, e.g. a small dog grooming shop]. I've attached [YOUR DATA, e.g. 6 months of sales and costs].

Build an interactive what-if model so I can test a price change before I make it.

Include:
1. Sliders for price change (minus 20 to plus 30 percent), number of customers or sales, and main costs.
2. Monthly revenue, costs and profit that update as I move the sliders, next to my current numbers.
3. The break-even point: how many customers I could lose at the new price and still make the same profit.
4. A simple chart of profit across the price range.
5. A plain-English note under the chart that explains what the numbers mean for me.

Use only my real numbers from the file. List any assumption you had to make at the top so I can correct it.
```

## Step by step

1. Export a few months of sales and costs from your sheet or bookkeeping app.
2. Open Gemini, attach the file and choose Canvas from Tools.
3. Paste the prompt and send it.
4. Move the sliders and ask Gemini to explain any number you don't trust.

## What you'll get

An interactive model with sliders, live profit figures, a break-even point and a plain-English note, built from your own numbers.
