# Additional Credits

> Add credits to your Helius plan when you run out. Card plans use autoscaling for automatic top-ups; crypto plans use prepaid credits purchased in USDC.

Every plan includes a monthly credit allocation. When you use it up, you can add more credits so your applications keep running without interruption. How you add credits depends on how you pay for your plan:

* **Card plans** use **autoscaling**, which automatically purchases additional credits as you need them.
* **Crypto plans** use **prepaid credits**, which you purchase manually in USDC.

Autoscaling requires a card on file, so it isn't available on crypto plans.

## Setting Up Autoscaling (Card Plans)

Autoscaling is configured on your Billing page:

1. Go to your [Billing](https://dashboard.helius.dev/billing) page
2. Find the Autoscaling section
3. Toggle autoscaling on

<Tip>
  Autoscaling is enabled by default on Business and Professional plans. See [autoscaling limits](#autoscaling-limits) for each plan's cap.
</Tip>

## Prepaid Credits (Crypto Plans)

Autoscaling requires a card on file, so it isn't available on crypto plans. If you pay in USDC, top up with prepaid credits instead:

1. Go to your [Billing](https://dashboard.helius.dev/billing) page
2. Click **Add credits**
3. Choose the amount and complete the purchase in USDC

<Note>
  Prepaid credits activate immediately and never expire. You keep them until they run out. For how to pay your plan in USDC and set up a wallet payment method, see [Pay with Crypto](/billing/pay-with-crypto).
</Note>

## Pricing for Additional Credits

Additional credits are priced at **\$5 per million credits** across all plans.

If you're consistently going over your limit, consider upgrading your plan for higher credit allocations and unlimited autoscaling.

<Tip>
  Using more than **200M credits per month**? An Enterprise plan can offer a lower per-credit rate. [Contact sales](https://www.helius.dev/contact) to discuss volume pricing.
</Tip>

## Notifications and Tracking Credit Usage

Helius keeps you informed about your credit usage to help manage your spend:

* **Email Alerts**: You'll receive notifications via email when you're approaching your credit limits and when autoscaling occurs.
* **Dashboard Tracking**: Check your current credit usage and historical data on the [Usage](https://dashboard.helius.dev/usage) page for detailed analytics.

## Autoscaling Limits

Autoscaling has a maximum amount of additional credits it can purchase each month, which depends on your plan. You set your own limit up to that maximum on your [Billing](https://dashboard.helius.dev/billing) page.

| Plan         | Maximum autoscaling | Default limit     |
| ------------ | ------------------- | ----------------- |
