# Virtual Booth Credit Calculator

This guide is designed to help you estimate exactly how many credits you’ll need for your upcoming **Virtual Booth** event. Because Virtual Booth generates content in the cloud, credits are used to power both AI transformations and digital background removals.

You can purchase additional credits at any time from your [dashboard](https://www.simplebooth.com/billing/virtual-booth-credits).

#### Credit Usage Rules

Before you start crunching numbers, keep these rules in mind:

* **Feature Exclusivity:** If an AI Effect is enabled, Background Replacement is automatically disabled. These features cannot be used at the same time.
* **No Regeneration Limits:** Unlike the HALO app, Virtual Booth does not have a setting to limit how many times a guest can "try again." Because guests can regenerate freely, it is wise to factor in a slightly larger buffer for your credit total.
* **Live Usage Only:** Credits are only consumed when a session is run during a live event. Testing your settings in the dashboard is always free.

***

#### Option 1: Using AI Effects

When using AI, your cost is determined by the specific model you choose. Since guests can regenerate their AI photos as many times as they like, you should factor in a buffer for multiple "generations" per session.

<table><thead><tr><th width="453.41015625">AI Model</th><th>Credits Per Generation</th></tr></thead><tbody><tr><td><strong>Nano Banana</strong> <br>Best for fastest results; individual participants</td><td>1x</td></tr><tr><td><strong>Nano Banana 2</strong> <br>Best for balance of speed/quality; groups up to 5</td><td>2x</td></tr><tr><td><strong>Nano Banana Pro</strong> <br>Best for best quality; groups up to 5</td><td>3x</td></tr></tbody></table>

#### Option 2: Using Background Replacement

If you choose to use digital background removal instead of AI, the credit consumption follows a "pay-per-action" structure. This includes both the captures (taking the photo) and the final upload.

* **Base Upload Fee**: 1 credit per photo uploaded.
* **Capture Fee**: 1 additional credit per picture taken.
* **Unlimited Retakes**: Guests can take as many photos as they want before uploading, but each "take" consumes 1 credit.
* **The "Rule of 3"**: Based on typical guest behavior (taking one or two photos before being satisfied), the average session uses 3 credits total.

Example Flow

Guest takes a photo (1 credit) → Guest dislikes it and hits "Retake" → Guest takes a second photo (1 credit) → Guest hits "Upload" (1 credit). Total: 3 credits.
{% endhint %}

#### Option 3: Plain Photos <a href="#h_cc21728975" id="h_cc21728975"></a>

If you choose not to use AI or Background Replacement for your Virtual Booth event, credits will not be consumed. You can still customize your pictures with a logo, overlays, or stickers.

#### Example Calculations

Use these scenarios to help predict your event needs.&#x20;

| AI-Powered Event (Nano Banana 2)                                                                          | Background Replacement Event                                                                           |
| --------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
| **Model Cost**: 2 credits per generation                                                                  | **Average Session Cost**: 3 credits (Capture + Retake + Upload)                                        |
| **Estimated Sessions**: 300                                                                               | **Estimated Sessions**: 300                                                                            |
| **Calculation**: 300 sessions × 2 credits = 600 credits                                                   | **Calculation**: 300 sessions × 3 credits = 900 credits                                                |
| **Recommended Buffer**: Purchase 750 credits to account for guests who choose to regenerate their images. | **Recommended Buffer**: Purchase 1,000 credits to ensure coverage for guests who take multiple retakes |

To calculate the total credits needed for your event, use the following formula:

$$
\[Estimated Total Sessions] × \[Max Credits Per Session] = Total Credits Needed
$$

#### Monitoring & Topping Up

You can [purchase more credits](https://www.simplebooth.com/billing/virtual-booth-credits) at any time from your account dashboard.

* **Pricing:** Credits cost **$0.10 each** and are sold in increments of 100 to 10,000.
* **No Expiration:** Any credits you purchase will remain in your account until they are used; they do not expire.
* **Low Credit Alerts:** You will receive email notifications when your balance is running low or if it hits zero. If you run out of credits mid-event, these features will stop working until more are added.
