Introduction
If you're running low on credits before your monthly refresh, paid subscribers can buy more at any time, either as a one-time purchase or automatically with auto-recharge. Purchased credits are tracked separately from your monthly plan credits.
🔷 Note: Free users cannot purchase credits. To buy credits, you'll need to upgrade to a paid plan. Enterprise workspaces get credits through their Gamma account team.
How do purchased credits work?
Credits power AI features in Gamma, such as:
Agent.
Adding slides with AI.
Ultra AI models (if available on your plan).
API access (if available on your plan).
When you use AI features, Gamma draws from your monthly plan credits first, then your purchased credits. Purchased credits are tracked separately from your plan credits and do not count toward your plan's rollover cap.
How much do credits cost?
Credit purchases start at $6 for 1,500 credits.
Credits are sold at one flat rate, so larger purchases cost the same per credit. There are no bulk discounts.
You can buy up to 2,000,000 credits in a single purchase.
The exact amount due, in your currency, is shown before you confirm.
How do I buy credits?
When you're low on or out of credits, click Add more on the credits message. You can also see your credits anytime in Settings > Billing.
Choose how you want to buy:
Buy once: pick one of the suggested amounts, or choose another amount from Other amounts, and confirm payment.
Auto-recharge: click Set up to have credits added automatically when you run low (see below).
🔷 Note: Buy once is available in single-member workspaces on any paid plan, and in Business workspaces of any size. Multi-member workspaces on Plus, Pro, Ultra, and Team can use auto-recharge instead.
On Business plans, purchased credits are added to your workspace's shared pool as workspace credits.
How do I set up auto-recharge?
Auto-recharge automatically buys credits when your balance falls below a threshold. It is never turned on by default: you have to set it up yourself, and only workspace admins can do it.
Click Add more, then click Set up under Auto-recharge.
Choose how many credits to add each time and the balance that triggers a recharge. The trigger starts at 500 by default.
Review the amount due, then click Enable auto-recharge.
💎 Pro Tip: If your balance is already at zero, turning on auto-recharge charges your payment method right away. The setup screen shows this as Amount due now before you confirm.
How auto-recharge works
Single-user workspaces:
When your balance drops below the threshold, Gamma automatically adds the amount you set and charges your payment method.
Multi-user workspaces on individual plans:
Each member has their own credit balance. When any member's balance drops below the threshold, credits are added to that member's account, and you are charged separately for each member who triggers a recharge.
Managing auto-recharge
Admins can turn auto-recharge off at any time with one click.
Auto-recharge turns off automatically as soon as a cancellation is requested, or when you downgrade to a plan with fewer monthly credits.
If you resubscribe or reactivate later, auto-recharge stays off until an admin turns it back on.
Auto-recharge isn't available for subscriptions billed through the App Store or Google Play.
Do purchased credits expire?
While subscribed: Purchased credits never expire.
If you cancel: Your credits remain available through the end of your billing period and are preserved after your account moves to the Free plan. Credits expire one year after your cancellation date.
Important: This 1-year preservation applies only to credits you purchased separately, on top of your subscription. It does NOT apply to your monthly plan credits (the credits included as part of your subscription). Those expire immediately when your paid subscription ends and are not preserved.
FAQs & Common Issues
Why can't I set up auto-recharge?
Only workspace admins can set up auto-recharge. If you're not an admin, contact your workspace administrator.
It's also unavailable while a cancellation is pending, and for App Store or Google Play subscriptions.
Was auto-recharge turned on without my permission?
Auto-recharge is never pre-selected. It only turns on after a workspace admin clicks Set up and then Enable auto-recharge.
Is there a limit on how many credits I can purchase?
Each purchase can be up to 2,000,000 credits. Purchased credits aren't limited by your plan's rollover cap.
Why don't I see the Buy once option?
In multi-member workspaces on Plus, Pro, Ultra, or Team, only auto-recharge is available. Business workspaces can use Buy once at any size.
What happens if I cancel my subscription?
Auto-recharge turns off automatically as soon as you request the cancellation.
After your plan ends, your account moves to Free. Your remaining purchased credits are preserved and expire one year after your cancellation date.
When do my credits refresh?
Your monthly credits refresh on your billing date. You can see your next refresh date in Settings > Billing.
What happens to my credits if I upgrade or downgrade?
Upgrade: You keep all existing credits and get your new plan's monthly allocation immediately.
Downgrade: When your new plan starts, any plan credits above your new plan's rollover cap are removed. Credits you purchased separately stay in full. Auto-recharge turns off.
Are credits shared across my team?
On individual plans, credits are assigned to each member individually, and auto-recharge applies per member.
On Business plans, credits are pooled.
Can I set different auto-recharge thresholds per teammate?
No. One threshold applies to the entire workspace.
What payment methods can I use?
We accept major credit and debit cards.
