# Auto Top-Up
> Automatically recharge your balance to keep resources running
Auto Top-Up is a powerful feature to help keep your account balance
positive. It helps safeguard your running resources from automatic
termination. We collect and securely store a specified payment method,
then automatically charge that payment method when your account balance
falls below a threshold. You configure the amount and the threshold.
## Enabling Auto Top-Up
Follow the instructions below to enable Auto Top-Up.
Go to **Settings → Billing** in the Hyperbolic dashboard.
Under Billing, select **Enable Auto Top-Up**.
Add at least one payment method to keep on file.
In **When my balance goes below…**, enter the balance that should trigger an automatic charge.
In **Automatically add**, enter the amount Hyperbolic should charge when your balance falls below the threshold.
Review the payment method, threshold, and top-up amount, then select **Confirm**.
You may add additional payment methods at any time, but there is only
ever one default payment method that is charged.
**Coming soon:** Customers will soon be able to specify a backup
payment method to use in the event that charging the default payment
method fails.
**Auto Top-Ups are not foolproof.** This is a convenience to make
balance management easier — make sure your payment method is valid and
your settings are configured correctly. We recommend a threshold equal
to **72h of usage** and a top-up amount equal to **24h of usage** to
prevent surprises and give plenty of time to remedy any issues. It is
your responsibility to maintain a positive balance in your account.
## How Auto Top-Up works
Auto Top-Up evaluates your balance **every 10 minutes** and may trigger
a charge at each evaluation if your balance meets the configured
threshold. It may miss massive spikes of usage that rapidly deplete
your balance within that timeframe.
The logic is conservative and avoids double-charging. If a payment
fails, it uses a backoff strategy to avoid creating problems with your
payment method (such as overdrafted accounts, account locks, or
triggered fraud rules).
Auto Top-Up will attempt multiple charges before giving up. If it
cannot successfully charge the payment method on file within the limits
of its retry policy, **you will be alerted and Auto Top-Up will be
automatically disabled**. You must correct the issue with your payment
method before re-enabling Auto Top-Up.
