AWS credits
Should you reserve while you still have AWS credits?
Yes, for the steady part of your fleet, and only with No Upfront. A credit can pay the hourly rate of a reservation. It never pays an upfront fee.
The rule
Credits pay hourly charges. They do not pay upfront fees.
Many small teams start on AWS credits. AWS Activate gives up to $5,000 (Founders) or up to $200,000 (Portfolio). Many of these teams wait to reserve until the credits end. That wait costs them. AWS states: "Credits don't apply to upfront costs for RIs or Savings Plans. However, credits can apply to instance hourly rates."
Upfront fees
AWS credits do not apply to the upfront fee of a Reserved Instance or a Savings Plan. An upfront payment is always cash.
Hourly rates
A credit can pay the hourly rate of a reservation. This works when the credit lists the service. Check the Applicable products column on the Credits page.
Nonprofit credits
The AWS Nonprofit credit is not valid for any fees or charges for Reserved Instances. Nothing in a reservation can use it.
Order of use
With more than one credit, AWS applies the credit that expires soonest first. The Credits page shows the expiry date of each credit.
By payment option
Only No Upfront is fully covered by a credit.
The AWS credit terms exclude any upfront fee for services such as Savings Plans and Reserved Instances. So the payment option decides how much of the bill a credit can pay.
| Payment option | The upfront fee | The hourly charge |
|---|---|---|
| No Upfront | None to pay | A credit can pay it |
| Partial Upfront | Cash only | A credit can pay it |
| All Upfront | Cash only | None to pay |
The upfront fee

- Partial UpfrontCash only
- All UpfrontCash only
The hourly charge

- Partial UpfrontA credit can pay it
- All UpfrontNone to pay
A credit pays the hourly part only if it lists the service. Open the Credits page in the Billing console and read the Applicable products column first.
Example: a startup on credits
The same credit lasts 26% longer.
Take a startup that spends $3,000 a month on compute. We assume 65% of it is steady and can be reserved. We use the lowest median 1-year No Upfront discount across RDS, ElastiCache, and EC2, which is 32%. With 1-year No Upfront reservations, the monthly bill falls to $2,381.
The $25,000 credit is an illustration. It is not an AWS amount. Your own credit, spend, and discount will differ. The runway gain comes from the lower reserved hourly rate, so it holds at any credit size.
The expiry date
A credit ends on a fixed date. A reservation term can run past it.
AWS credits expire on the date stated, with no refund. After that date your card pays the reserved rate. That rate is still below on-demand for an instance that runs all the time.
Reserve only what will still run after the credits end. Then put the credit expiry date and every reservation end date on one calendar.The Billing console shows each credit's expiry date. The expiry radar in Reserver shows the reservation side. The two dates together tell you what the first card bill will look like.
Paying upfront while credits remain spends cash and leaves the credit to expire unused. That is the one mistake to avoid.
How this scales with you
Every size meets credits at a different point.
You are on Activate credits. Reserve the steady part of your fleet with No Upfront now. Do not pay upfront, because cash is the one thing a credit cannot replace.
Your credits ended or are about to end. The first card bill is the on-demand cliff. Reserve before the credit expiry date, so the first bill already shows the reserved rate.
Credits from an AWS program or a private agreement carry their own terms. Read the Applicable products of each credit. Check the credit-sharing setting on the payer account.
Where Reserver fits
Reserver shows the reservation side. It does not see credits.
Reserver does not read credit balances or credit expiry dates. Its connection role has no billing permission. It scans your instances and reservations, and it shows when each reservation ends. You read the credit expiry date in the Billing console and compare the two.
Use the free Expiry Check tool to see which reservations end soon. For the steps at renewal, read the renewal playbook. For the size of the saving, read how much a reservation saves.
Should I reserve while I still have AWS credits?
Yes, for the part of your fleet that runs all year. Choose No Upfront. A credit can pay its hourly rate, and the lower rate makes the credit last longer. Do not pay upfront, because credits never pay an upfront fee.
Can AWS credits pay for a Reserved Instance?
Only the hourly part. AWS states that credits do not apply to upfront costs for Reserved Instances or Savings Plans. They can apply to instance hourly rates.
What if the reservation ends after my credits expire?
Your card pays the reserved rate from the expiry date. That rate is still below on-demand for an instance that runs all the time. Reserve only what you expect to keep running after the credits end.
Do AWS Nonprofit credits pay for Reserved Instances?
No. AWS states that the nonprofit credit is not valid for any fees or charges for Reserved Instances.
How do I find my credit expiry date?
Open the Credits page in the Billing console. It shows the expiration date and the applicable products of each credit. If you have more than one credit, AWS uses the one that expires soonest first.
Does Reserver read my credit balance or credit expiry date?
No. The Reserver connection role has read-only access to your instances and reservations. It has no billing permission. Reserver shows the end date of each reservation. You add the credit expiry date from the Billing console yourself.
