Carnival onboard credit (OBC) is money loaded onto your Sail & Sign account that pays for extras on your cruise, such as gratuities, specialty dining, spa treatments, shore excursions, Wi-Fi and drinks. It cannot be put toward your cruise fare, taxes or port fees, and most promotional credit is non-refundable, so any balance left at the end of the sailing is simply lost. The smartest move is to point it at costs you would pay anyway, starting with daily gratuities.

Below we explain the different kinds of Carnival onboard credit, the main ways to earn it in 2026, where it works best, what it will not cover, and how to keep track of your balance so none of it goes to waste.
What Is Carnival Onboard Credit?
Onboard credit is a dollar amount attached to an individual booking and applied to your shipboard account, which Carnival calls Sail & Sign. Every purchase you make on the ship, from a cappuccino to a massage, is charged to that account. When credit is present, those charges are paid from the credit first and only the remainder lands on your credit card or cash deposit.
OBC is tied to the stateroom or guest it was issued to. Carnival’s promotional terms describe most offers as non-transferable, and they state that the credit may not be applied to cruise fare, required cruise fees and expenses, or government taxes and fees. In other words, OBC is for spending once your trip is paid for, not for lowering the price of the trip itself.
Refundable vs Non-Refundable OBC
Not all credit behaves the same way, and knowing which type you hold changes how you should spend it.
| Type | Typical sources | Cash value? | Leftover balance |
|---|---|---|---|
| Non-refundable OBC | Carnival booking promotions, Lowest Price Guarantee credit, shareholder benefit, many travel agent offers, Future Cruise offers | No | Forfeited at the end of the cruise |
| Cruise Cash (purchased) | Bought by you, friends or family at carnival.com/cruise-cash | No | Forfeited (Carnival calls it “use it or lose it”) |
| Refundable funds | Your own cash deposit, Carnival gift cards applied onboard | Yes, or returned as a new gift card | Refunded; unused gift card value is mailed back as a new card |
Your account generally applies non-refundable credit to charges before refundable money, which works in your favour. If you are unsure which bucket your credit sits in, Guest Services can show you a breakdown of your balance.
How to Get Carnival Onboard Credit
There are more routes to OBC than most first-time cruisers realise. These are the main ones for Carnival sailings in 2026.
- Booking promotions. Carnival’s sales often include “up to” a set amount of onboard credit, with larger amounts usually reserved for balconies and suites. Compare these offers when you shop our roundup of the best cruise deals for 2027.
- Travel agents. Many agencies add their own OBC on top of Carnival’s offer. It costs nothing to ask an agent what they can include before you book direct.
- Lowest Price Guarantee. If you find a lower Carnival-advertised price for the same cruise and submit a claim within 48 hours of booking, Carnival’s terms say the difference is paid as non-refundable onboard credit.
- Carnival Rewards milestones. Carnival Rewards replaced the VIFP Club on 1 September 2026. Under the new programme, onboard credit is part of the milestone rewards tied to days sailed (50 days, 100 days and every 100 days after), and members can also redeem points toward things like excursions, spa treatments and specialty dining.
- Future Cruise and rebooking offers. Booking your next sailing while onboard, or through the post-cruise rebooking window, frequently comes with a small OBC bonus per stateroom.
- Shareholder benefit. Owners of at least 100 shares of Carnival Corporation can claim OBC per stateroom: $50 on sailings of six days or fewer, $100 on seven to 13 days and $250 on 14 days or more. Claims must be submitted ahead of the cruise, and this credit has its own restrictions, so read the current rules on the Carnival Corporation website.
- Cruise Cash and gift cards. You or others can buy Cruise Cash in $25 to $100 amounts up to two days before debarkation. Carnival gift cards can pay toward your fare or be added to your onboard account, and buying them at a discount is one of the easiest ways to stretch your budget. Our guide on how to buy discounted Carnival gift cards explains where to look and the pitfalls to avoid.
- Casino offers. Regular casino players sometimes receive mailed offers that include free or discounted cruises and onboard credit. These are targeted, so there is no guarantee you will qualify.
The Best Ways to Use Carnival Onboard Credit
The golden rule is simple: spend your credit on things you were going to buy anyway. That turns OBC into real savings rather than an excuse to buy extras you did not need.
1. Gratuities (the safest bet)
Carnival adds a daily gratuity to every guest’s account. For sailings departing on or after 2 April 2026, the rate is $17 per person per day in interior, ocean view and balcony staterooms, and $19 per person per day in suites. For two people on a seven-night balcony cruise, that is $238 before you buy a single drink. If you have not prepaid gratuities, most promotional OBC will cover them automatically as they post, which makes this the most reliable way to use credit in full.
2. Specialty dining
Steakhouse dinners, sushi, teppanyaki and Italian specialty restaurants all charge to Sail & Sign, as do many à la carte venues. A single specialty dinner for two can absorb a typical promotional credit in one evening.
3. Spa treatments and thermal suites
Massages, facials and thermal suite passes can be paid with OBC. If you are weighing up whether to book a spa cabin for the extra perks, read our look at whether Carnival Cloud 9 Spa rooms are worth it before you spend.
4. Shore excursions
Carnival-booked excursions can be paid for with onboard credit. Some guests prefer to pre-book online so popular tours do not sell out and then let the credit offset the charge once onboard; check how your particular credit applies before you sail.
5. Drinks and drink packages
Bar tabs, specialty coffees and soft drink packages all draw on OBC. Bottomless Bubbles rose to $11.99 per day for adults in 2026, plus the service charge, so a soda package can eat through credit quickly on longer sailings.
6. Wi-Fi, photos and laundry
Internet plans, professional photo packages and laundry services can usually be charged to your account, so they are good homes for any credit left late in the cruise. On a few older ships with coin-operated launderettes, laundry may not be payable this way.
7. Onboard shops
The ship’s boutiques accept Sail & Sign charges, so leftover credit on the final night can go toward souvenirs, sundries or toiletries you would otherwise buy at home. Prices are not always better than on land, so treat this as a last resort.
What Carnival Onboard Credit Cannot Be Used For
- Your cruise fare, taxes, port fees or required cruise fees. Carnival’s promotional terms rule these out.
- Cash. Promotional OBC and Cruise Cash have no cash value and cannot be withdrawn at Guest Services.
- Future cruises. Credit is valid for one sailing only and does not roll over.
- Casino cash-outs. Rules depend on the type of credit. Some credit, including shareholder OBC, cannot be used in the casino, and where play is allowed you can only cash out winnings, not the credit itself. Ask the casino host before you sit down.
- Gratuities, in some cases. Shareholder credit is reported to exclude gratuity charges, and specialty products such as Cruise Cash Bar or Cruise Cash Photo only cover their own category.
- Onshore spending. Anything you buy in port with your own card is outside your Sail & Sign account.
How to Check Your Onboard Credit Balance
Before you sail, your OBC should appear in your booking details on carnival.com, often in the invoice or booking summary for each stateroom. Once onboard, open the Carnival HUB app, connect to the ship’s network and look for your Sail & Sign account or charges section, which lists purchases and credits applied. You can also visit Guest Services or an onboard kiosk for a printed statement that separates refundable and non-refundable amounts.
It is worth checking on the first day. If an expected travel agent or promotional credit is missing, it is far easier to sort out early in the cruise than on the last night.
What Happens to Unused Carnival Onboard Credit?
Non-refundable OBC and Cruise Cash are forfeited when the cruise ends. There is no refund, no transfer to a cabinmate in another stateroom and no carry-over to your next booking. Refundable money, such as a cash deposit, is returned, and leftover value from Carnival gift cards applied onboard is typically sent back as a new gift card.
A useful habit that most guides skip: on the second-to-last day, check your balance against the gratuities still to post. Because gratuities are charged daily, you can work out exactly how much credit remains after the final day’s tips and then spend only the true surplus, rather than guessing and either leaving money behind or overshooting onto your card.
If you are expecting a large credit, read our guide on whether to prepay Carnival gratuities before you decide, because onboard credit generally can’t be used to prepay them.
