How Many Calories Are In An Arby’s Crispy Fish Sandwich? | Quick Facts Guide

If you’re eyeballing the crispy fish during the seasonal run, the headline number is 570 calories for one standard sandwich. That count includes the breaded Alaskan pollock fillet, sesame bun, tartar sauce, and lettuce. The fillet brings lean protein; the bun and sauce add most of the energy and sodium.

Calories In Arby’s Crispy Fish Sandwich: What Changes It

Calories hinge on three levers: portion size, sauce, and add-ons. The listed 570 calories come from Arby’s posted nutrition panel for the standard build. Sub in cheese, double the sauce, or pick a deluxe seasonal variant and you nudge the number higher. Skip sauce and you trim a noticeable slice.

Core Nutrition At A Glance

Here’s a compact breakdown of the standard sandwich. Use it to budget your meal or compare against your day’s targets.

Component	Amount	Notes
Serving Size	228 g	Whole sandwich, standard build
Calories	570 kcal	Mainly bun + breading + sauce
Protein	~20 g	From pollock fillet
Total Fat	~25 g	~4 g saturated
Carbohydrates	~65 g	~3 g fiber; ~9 g sugars
Sodium	~990 mg	High for one item
Allergens	Fish, wheat, soy, egg, sesame	Standard build; cheese adds milk

Once you know your daily calorie needs, it’s easier to see where a fried fish sandwich fits. Some folks will treat it as the main meal; others will split it with a side salad later.

What Counts As “Standard” For This Item

The listing assumes one breaded pollock fillet, sesame seed bun, tartar sauce, and shredded lettuce. Regional or limited items keep the same base fish but stack extra ingredients such as cheese or a different bun. Those swaps shift calories and sodium because sauces and buns swing the numbers far more than the fish itself.

How The Calorie Number Was Determined

Fast-food chains publish nutrition PDFs that include serving weights and macros by item. The most recent U.S. file shows 570 calories for this sandwich alongside ~25 g fat, ~65 g carbs, ~20 g protein, and ~990 mg sodium. That document also lists allergens and ingredients so diners can plan around restrictions. You can verify this by checking Arby’s current nutrition PDF.

How It Fits A Balanced Day

At ~990 mg sodium, one sandwich already lands near half of a 2,300 mg daily cap used on U.S. labels. If you’re watching blood pressure or you’re simply aiming for a lighter day, spacing out salty sides helps. The FDA sodium guidance lays out practical ways to balance high-sodium meals with lower-sodium choices later.

Smart Swaps That Lower Calories

Small tweaks go a long way. The fish brings lean protein, so trims usually target bun and sauce. Here are practical moves that keep the sandwich satisfying without ballooning the count.

Hold Or Lighten The Sauce

Tartar adds tang and moisture, but it’s calorie-dense. Ask for light sauce or packets on the side so you can control the spread. If you enjoy the flavor punch, try half the usual amount. The crunchy breading and lettuce still deliver texture.

Skip The Cheese

Some stores offer a cheese add-on or a cheddar version. Cheese lifts fat and sodium. If you’re after lower calories, pass on it. If you want that melty bite, pair it with a half-sauce request to even things out.

Mind The Sides

Fries plus a shake turns a reasonable sandwich into a heavy meal. Pair with water or unsweetened tea and add a side salad when available. If you’re craving fries, share a small size and keep the sandwich as the star.

Portion Tricks That Actually Work

When appetite is in flux, sizing strategies help you stick to your plan without feeling boxed in.

Split And Save

Eat half now, half later. Wrap the rest and keep it chilled; reheating in an air fryer brings back crunch without extra oil. This tactic preserves taste while cutting the immediate calorie hit.

Protein First Bites

Start with a few bites of the fish itself. Protein tends to satisfy quickly. If you still want every crumb, go for it—this trick just helps your stomach set the pace.

Comparing Variants And Limited Items

Seasonal fish builds pop up during certain months. The baseline crispy fish sits around 570 calories; a cheddar-topped version trends lower fat than “deluxe” builds but higher sodium; a King’s Hawaiian version tends to be the heaviest because of a richer bun and extra toppings. Expect the range to run roughly from the low-500s to near 700 calories depending on toppings and bun.

Ingredient Notes

The fillet is pollock, a mild white fish with a light, flaky texture that holds breading well. The bun is a sesame seed style; the sauce is a mayo-based tartar with sweet relish. Shredded lettuce adds volume with minimal calories. If you have allergies, the standard build lists fish, wheat, soy, egg, and sesame; cheese-topped versions add milk.

Make The Numbers Work For You

Think in trades. If you want the full sauce and a cheese slice, trade fries for a zero-cal beverage. If you want fries, keep the sandwich basic and skip dessert. These swaps keep flavor in play while keeping calories near your goal.

Budgeting A Full Meal

Here’s a quick framing: 570 calories for the sandwich, small fries can add 250–400 depending on cut and oil, and shakes start at several hundred. Water, diet soda, or unsweetened tea add essentially none. The simplest way to stay on track is to pick two out of three: sandwich, fries, dessert—then keep the drink light.

Customization Impact: Common Requests

These are practical estimates for everyday swaps. Actual numbers vary by store and portion control, but the direction holds true.

Change	Estimated Calorie Shift	What To Expect
No Tartar Sauce	−60 to −100	Drier bite; fish flavor stands out
Light Tartar	−30 to −60	Keeps tang with fewer calories
Add One Cheese Slice	+40 to +60	Creamier mouthfeel; more sodium
Extra Sauce	+60 to +100	Richer taste; calorie bump
No Bun (Knife & Fork)	−160 to −200	Lower carbs; still crunchy
Swap Fries For Side Salad	−150 to −300	Saves room for dessert or a snack

Frequently Asked Calorie Questions (Without The Fluff)

Is The Fish Itself “Heavy”?

The fish isn’t the heavy hitter. A lean pollock fillet brings solid protein with modest calories. The breading, bun, and sauce drive the total.

What About Protein?

About 20 grams is a solid showing for a sandwich in this category. That’s enough to help with satiety, especially if you eat it slowly and pair it with a fiber-rich side.

How Do I Keep Sodium In Check?

Order the sandwich basic and keep the rest of the meal simple—no cheese, light sauce, and a non-salted side when possible. Space out other salty items during the day to stay closer to label targets.

Practical Ordering Playbook

Lighten Without Losing Flavor

• Ask for “light tartar” or packets on the side.
• Skip cheese by default; only add it if you plan to share fries.
• Choose water or unsweetened tea; save sweet drinks for a different day.

When You Want The Heft

• Add a cheese slice and keep the full sauce.
• Pick one side, not two.
• Enjoy it as your main meal and keep the rest of the day simple.

Allergen And Ingredient Transparency

The posted allergen list includes fish (pollock), wheat, soy, egg, and sesame in the standard build; a cheddar version includes milk. If you avoid any of these, a no-bun, no-sauce approach can reduce exposure, but cross-contact remains possible in shared kitchens. Always ask staff if you have strict needs.

Bottom Line That Helps You Order

The default crispy fish lands at 570 calories with a good protein hit and a salty profile. Keep the sandwich basic to stay closer to that number; stack cheese or extra sauce and it climbs. If you’re watching sodium, pick a lighter drink and side, then keep later meals fresh and low-salt.
