A buy rate is the percentage of a card's market price that you pay for it. When you click **Apply store buy rates** during an appraisal, the rates set here fill in the amounts. Set them under **Settings** › **Buy rates**. Only owners and admins can change them.

## How a buy price is worked out

An appraisal amount is the card's reference market price multiplied by the buy rate, then rounded. For example, a card with a market price of ¥10,000 at an 80% rate is appraised at ¥8,000.

The rate is chosen like this:

1. Enabled price-range rules are checked in order, lowest number first. If the market price falls inside a rule's range, that rule's buy rate is used.
2. If no rule matches, the **Default buy rate** is used.

## Basic settings

Set these three at the top of the page.

| Setting                        | What it does                                                                                           |
| ------------------------------ | ------------------------------------------------------------------------------------------------------ |
| Default buy rate               | The rate for cards no rule matches. 0–100%, up to 2 decimal places                                     |
| Box, pack & deck rate          | The rate for sealed products. Leave it blank to use **Same as default**                                |
| Default grade for single cards | The grade selected first when a card is added to an appraisal. Can also be **None (choose each time)** |

## Advanced settings

Open **Advanced settings** at the bottom of the page for the following.

### Buy rate rules

To use different rates for different price ranges, click **Add rule**. Each rule has a **Minimum price (¥)**, **Maximum price (¥)** and **Buy rate (%)**. Both the minimum and maximum are included in the range. A blank side has no limit.

Rules are listed by number, and a switch turns each one on or off. Remove a rule you no longer need with **Delete rule**.

### Rounding

Choose how to handle fractions in appraisal amounts: **Round down**, **Round up**, **Round to nearest** or **Don't round**. Then choose the unit: ¥1, ¥10, ¥100 or ¥1,000.

### Review threshold

Cards appraised at or above this amount need a review before the quote goes out. At ¥0, every card needs a review. The review process is covered in [Research and reviews](/en/guides/purchase/research-and-reviews).

:::note
If your shop has only one member besides view-only members, there's nobody to ask for a review, so quotes can go out without one.

### Lookback period

Choose how far back, from 1 to 121 months, market price records are used when judging a card's market price.
