Types of credits
You can hold up to four different types of credits at the same time. Each one has its own rules about when it refills and whether unused credits roll over.| Type | Refills when | Rolls over? | Where it comes from |
|---|---|---|---|
| Purchased credits | Never automatically | Yes, kept until used | Your signup bonus, paid top-ups, referral rewards |
| Free daily credits | Every day at 00:00 UTC | No, unused credits are lost | Every account, including paid plans, gets 100 free credits per day |
| Plan monthly credits | When a new billing cycle starts | No, reset at the cycle start | Your paid plan’s monthly allowance (Plus = 2,000/month, Pro = 15,000/month, and so on) |
| Promo credits | Defined per promo | No, expire at promo end | Time-limited promotions (e.g. a launch event that grants every shop extra credits) |
Free daily credits do not stack
Free daily credits are a budget that refills, not a deposit. If you don’t use Ninja today, you still start tomorrow with 100, not 200. Unused credits are lost at midnight UTC. Plan monthly and promo credits work the same way. Only purchased credits roll over indefinitely.In what order are credits spent?
When you run a task, Ninja drains your credit buckets in this exact order:- Promo credits first
- Free daily credits next
- Plan monthly credits next (if you are on a paid plan, oldest active billing cycle first)
- Purchased credits last
How your “credits remaining” total is calculated
The single number you see in your dashboard is the sum of all four buckets:Worked example 1: a Free-plan user, two tasks in one day
Anna signs up and receives a 500-credit signup bonus.| Day | What she does | Buckets after |
|---|---|---|
| 0 | Signs up | Purchased: 500, Free daily: 100/100 → total 600 |
| 1 | Runs a task that costs 30 | Free daily covers all 30. Free daily: 70/100 → total 570 |
| 1 | Runs another task that costs 80 | Free daily covers the first 70, the last 10 come from purchased. Purchased: 490, Free daily: 0/100 → total 490 |
| 2 (00:00 UTC) | Free daily resets | Purchased: 490, Free daily: 100/100 → total 590 |
| 2 | No usage | Same → total 590 |
| 3 | No usage | Same → total 590 |
Worked example 2: a paid-plan user
Bela is on the Plus plan. He gets 2,000 monthly credits + 100 free credits per day, and he also has 500 purchased credits from a previous top-up. His billing cycle just renewed. He runs a single task that costs 250 credits.| Bucket | Before | Spent on this task | After |
|---|---|---|---|
| Promo | 0 | 0 | 0 |
| Free daily | 100 | 100 | 0 |
| Plan monthly (current cycle) | 2,000 | 150 | 1,850 |
| Purchased | 500 | 0 | 500 |
Worked example 3: a promo period
The “Nano Banana Launch” promo grants every shop on Shopify, UNAS, Shoprenter, Shoper, and Scraper feeds an extra 10,000 credits for 5 days. Csilla starts the promo with 200 purchased credits and a fresh 100 daily bucket. She runs a single task that costs 3,000 credits.| Bucket | Before | Spent | After |
|---|---|---|---|
| Promo | 10,000 | 3,000 | 7,000 |
| Free daily | 100 | 0 | 100 |
| Purchased | 200 | 0 | 200 |
Frequently asked questions
My balance has not changed in days, even though I'm on the Free plan. Where are my 100 credits per day?
My balance has not changed in days, even though I'm on the Free plan. Where are my 100 credits per day?
The Free plan gives you 100 credits of usage per day, not 100 credits added to your balance each day. Unused free credits do not carry over. If you do not use Ninja today, tomorrow you will
still start with 100, not 200.
What is the maximum balance I can reach on the Free plan?
What is the maximum balance I can reach on the Free plan?
The Free plan does not grow your balance over time. It gives you a 100-credit daily usage budget that resets every day at 00:00 UTC. To accumulate credits, you need to buy a top-up, earn referral
rewards, or subscribe to a paid plan.
I see a negative number in my balance. Did I get charged?
I see a negative number in my balance. Did I get charged?
No, we never bill you money for credit overruns. A negative number means a past task cost more than the credits available in your daily, monthly, and promo buckets, so the difference was taken
from your purchased balance and pushed it below zero. You will not be able to run new tasks until your balance returns to zero or positive, which happens when you upgrade to a paid plan, buy a
top-up, or a promo period covers your usage. If you think your balance is wrong, contact support.
I received credits during a promo. Where did they go?
I received credits during a promo. Where did they go?
Promo credits live in a separate bucket from your purchased balance. They are spent first (before your free daily, monthly, or purchased credits) and they expire when the promo ends. Any unused
promo credits at the end of the promo period are forfeited.
Do my paid monthly credits roll over to next month?
Do my paid monthly credits roll over to next month?
No. Your monthly plan allowance resets at the start of each billing cycle, so unused credits from the previous month are lost. If you regularly have a lot of credits left over, consider
downgrading to a smaller plan and topping up purchased credits as needed.
