Understanding In-N-Out Burger menu prices helps you decide between a Protein Style and a regular burger. If you are curious about what you can actually order off the not-so-secret menu and how much it costs, you have come to the right place. Knowing the in-n-out secret menu prices can save you money and help you pick the best meal for your budget.
In-N-Out is famous for its simple menu, but the secret options are what keep fans coming back. From Animal Style fries to a Neapolitan shake, these items are not listed on the main board. But they are real, and they have real prices. This guide breaks down every secret menu item and its cost so you can order with confidence.
Why The Secret Menu Matters For Your Wallet
Many people think the secret menu is a gimmick. It is not. It is a way to customize your food without paying extra for every little change. Some items are free modifications, while others cost a bit more. Knowing the difference helps you avoid surprise charges.
For example, ordering a burger “Protein Style” (wrapped in lettuce instead of a bun) costs the same as a regular burger. But adding extra patties or cheese will increase the price. The in-n-out secret menu prices are generally very reasonable, but you still need to know what you are paying for.
In-n-out Secret Menu Prices
This section covers the most popular secret menu items and their exact prices. Prices may vary slightly by location, but these are the standard costs as of 2025. Always check with your local store for the most current pricing.
Animal Style Burger
The Animal Style burger is the most famous secret menu item. It comes with a mustard-cooked beef patty, extra spread, pickles, grilled onions, and lettuce. This is not a different burger; it is a modification of the standard Double-Double or single burger.
- Animal Style Single: Approximately $4.50
- Animal Style Double-Double: Approximately $5.80
- Animal Style Cheeseburger: Approximately $4.10
These prices are very close to the regular menu items because the modification is mostly free. The extra spread and grilled onions do not cost extra. The only added cost is if you add extra cheese or patties.
Protein Style Burger
This is a low-carb option where the bun is replaced with a large lettuce wrap. It is a free modification. You can order any burger Protein Style without paying more. The price is exactly the same as the regular burger.
- Protein Style Hamburger: $3.60
- Protein Style Cheeseburger: $4.10
- Protein Style Double-Double: $5.80
This is a great option if you are watching your carbs or just want a lighter meal. The lettuce wrap is fresh and crisp, and it holds the burger together well.
Animal Style Fries
Animal Style fries are a fan favorite. They are regular fries topped with melted cheese, spread, and grilled onions. This is one of the few secret menu items that costs extra because of the added ingredients.
- Animal Style Fries (Small): Approximately $4.80
- Animal Style Fries (Medium): Approximately $5.30
- Animal Style Fries (Large): Approximately $5.80
These prices include the base fries plus the toppings. The regular fries cost about $2.50 for a small, so you are paying roughly $2.30 extra for the cheese, spread, and onions. It is worth it for the flavor.
Neapolitan Shake
This is a three-flavor shake combining chocolate, vanilla, and strawberry. It is not listed on the menu, but you can order it by asking for a “Neapolitan shake.” The price is the same as a regular shake.
- Neapolitan Shake: Approximately $3.80
You get all three flavors in one cup, swirled together. It is a fun option if you cannot decide on a single flavor. The price is identical to a standard shake, so no extra cost.
Flying Dutchman
The Flying Dutchman is a meat-and-cheese-only item. It consists of two beef patties with two slices of cheese melted between them. No bun, no veggies, no spread. It is a protein-packed option for low-carb dieters.
- Flying Dutchman: Approximately $3.30
This is one of the cheapest secret menu items. It is essentially two patties and cheese, so the price is lower than a full burger. You can add extra patties or cheese for an additional cost.
Grilled Cheese
This is a vegetarian option. It is a bun with melted cheese, grilled onions, lettuce, tomato, and spread. It is essentially a cheeseburger without the patty. The price is similar to a regular cheeseburger but slightly less because there is no meat.
- Grilled Cheese: Approximately $3.80
This is a good option for vegetarians or anyone who wants a lighter meal. You can also add extra cheese or grilled onions for free.
3X3, 4X4, And More
You can order a burger with three, four, or even more patties. This is called a 3×3 (three patties, three cheese slices) or a 4×4 (four patties, four cheese slices). The price increases with each extra patty.
- 3×3: Approximately $6.50
- 4×4: Approximately $7.20
- 5×5 (if available): Approximately $7.90
Each additional patty costs about $0.70 to $0.80 extra. The same applies to cheese slices. These burgers are huge, so be prepared for a big meal.
Animal Style Protein Style
You can combine modifications. For example, you can order a Protein Style burger with Animal Style toppings. This is a free modification on top of the regular burger price. The cost is the same as a regular Protein Style burger.
- Animal Style Protein Style Double-Double: $5.80
This is a great way to get the flavor of Animal Style without the bun. The lettuce wrap holds the spread and grilled onions well.
Mustard Grilled Patty
This is a modification where the patty is cooked with mustard on it. It is a free change. You can ask for any burger to have a “mustard grilled patty” without extra cost. The price remains the same as the regular burger.
- Mustard Grilled Cheeseburger: $4.10
The mustard adds a tangy flavor that complements the beef. It is a simple way to change the taste without spending more.
Well-Done Or Extra-Toasty Buns
You can ask for your bun to be extra-toasted or your patty to be well-done. These are free modifications. The price does not change. Just tell the cashier you want a “well-done patty” or “extra-toasty bun.”
- Well-Done Double-Double: $5.80
This is a good option if you prefer a crispier bun or a more cooked patty. It is a simple request that costs nothing.
Chopped Chilies
You can add whole or chopped chilies to any burger. This is a free addition. The chilies are pickled and add a mild heat. The price of the burger stays the same.
- Cheeseburger with Chopped Chilies: $4.10
This is a popular customization for those who want a little spice. The chilies are not listed on the menu, but they are always available.
Roadkill Fries
This is an unofficial name for fries topped with a patty, cheese, spread, and grilled onions. It is essentially Animal Style fries with a patty on top. The price is the base fries plus the cost of a patty.
- Roadkill Fries (Small): Approximately $5.80
- Roadkill Fries (Medium): Approximately $6.30
- Roadkill Fries (Large): Approximately $6.80
This is a filling meal on its own. The patty adds protein and makes the fries a full entree. The price is reasonable for the amount of food you get.
Monkey Style Fries
This is another unofficial name. It is fries topped with a patty, cheese, and a bun. Some people call it a “Fries Burger.” The price is similar to Roadkill fries but with a bun included.
- Monkey Style Fries (Small): Approximately $6.00
This is a messy but delicious option. The bun adds carbs and texture. It is not a standard order, so you may need to explain what you want.

Regional Price Variations
In-N-Out prices can vary by location. Stores in California may have slightly different prices than stores in Texas or Nevada. The in-n-out secret menu prices are generally consistent, but you should expect small differences.
For example, a Double-Double in Los Angeles might cost $5.80, while the same burger in Dallas might be $5.60. The secret menu items follow the same base prices. Animal Style fries might be $4.80 in one city and $5.00 in another. Always check the menu board for base prices and add from there.
If you are traveling, ask the cashier for the exact price of your order. They will tell you the total before you pay. This is especially important for custom orders like a 4×4 or Roadkill fries.
Tips For Saving Money On Secret Menu Items
You can save money by ordering smartly. Here are some practical tips.
- Stick to free modifications: Order Protein Style or Animal Style toppings instead of adding extra patties. These are free and change the flavor.
- Share large items: A 4×4 or large Roadkill fries can feed two people. Split the cost and save money.
- Skip the shake: A Neapolitan shake is fun, but it costs the same as a regular shake. If you are on a budget, stick to water or a regular drink.
- Order the Flying Dutchman: This is the cheapest protein option. Add free toppings like grilled onions and spread to make it more filling.
- Use the app: In-N-Out does not have a mobile app, but you can check prices online before you go. Some locations have digital menu boards with prices.
These tips will help you enjoy the secret menu without overspending. The key is to focus on free modifications and share large items when possible.
Common Mistakes When Ordering
Many people make mistakes when ordering from the secret menu. Here are some common errors and how to avoid them.
- Assuming all items are listed: The secret menu is not written down anywhere. You have to know the names. Study this guide before you go.
- Not specifying the size: If you order Animal Style fries, say if you want small, medium, or large. Otherwise, the cashier will give you the default size.
- Forgetting to ask for modifications: If you want a well-done patty or extra-toasty bun, you have to ask. The cashier will not assume.
- Expecting the same price everywhere: Prices vary by location. Do not be surprised if the cost is slightly different from what you read online.
- Ordering too much food: Secret menu items can be large. A 4×4 with Animal Style fries is a lot of food. Start small and add more if you are still hungry.
Avoiding these mistakes will make your ordering experience smoother and more enjoyable. The secret menu is meant to be fun, not confusing.
