OSRS Food Consumption Calculator

Calculate your hitpoint restoration efficiency in OSRS. Compare healing per slot, combo eating delays, and cost-per-HP for all major food sources from Salmon to Manta Rays.

Estimated based on boss mechanics

How It Works

The OSRS Food Consumption Calculator is the definitive guide for survival in PVM and PVP. By analyzing the healing values of various food types, their cost on the Grand Exchange, and their "Healing per Inventory Slot" efficiency, you can make informed decisions about your combat loadout. Whether you need the high burst healing of combo-eating Shark and Karambwans or the sustained efficiency of Saradomin Brews, this tool provides the mathematical breakdown you need to survive.

Formula Used

Healing efficiency = (Total HP Restored / (Inventory Slots × Attack Delay Penalty)) × Cost Multiplier

Real Calculation Examples

  • 1Shark heals 20 HP and adds a 3-tick delay to your next attack.
  • 2A full Saradomin Brew (4 doses) heals 64 HP per inventory slot at level 99.
  • 3Combo Eating: Shark (20) + Karambwan (18) = 38 HP in a single game tick.

The Definitive OSRS Food & Hitpoints Management Guide

In Old School RuneScape, your Hitpoints (HP) are your most valuable resource. But staying at full health isn't just about clicking a fish when your bar turns red. It's about Inventory Efficiency, Tick Management, and Cost Analysis. Our OSRS Food Consumption Calculator breaks down the complex math of 2026-meta survival.

1. Healing per Inventory Slot: The Efficiency King

When you enter a dungeon, you only have 28 slots. Every slot taken by food is a slot that can't hold a potion or a rare drop. This is why "Healing per Slot" is the most important metric for long trips.

Food Type Healing per Slot (Total) Doses/Bites per Slot
Saradomin Brew (Lvl 99) 64 HP 4 Doses
Guthix Rest Tea 20 HP 4 Doses (No attack delay!)
Manta Ray / Sea Turtle 22 HP 1 Bite
Shark 20 HP 1 Bite
Anglerfish 22-24 HP 1 Bite (Over-heals)
Pizza (Pineapple/Meat) 22 HP 2 Bites

Notice that Saradomin Brews offer nearly 3x the healing per slot of a Manta Ray. However, they come with a "Stat Penalty" that requires Super Restores. Our calculator helps you find the balance—typically a 3:1 Brew-to-Restore ratio is the gold standard for high-level PvM.

2. Mastering the Combo Eat & Triple Eat

In OSRS, the game engine handles different "Action Types" differently. You can combine actions in a single 0.6-second game tick to burst-heal yourself out of range of a boss's max hit.

  • Standard Combo (Shark + Karambwan): Heals 38 HP. Use this when a boss like Jad hits you for a 50+ and you need to recover fast.
  • The Triple Eat (Manta + Brew + Karambwan): Heals up to 56 HP. This is the ultimate survival move, commonly used in high-risk Wilderness combat or against Nex during the "Containment" phase.

Our calculator includes a Tick Delay Visualizer. Every time you eat a standard fish, your attack is delayed by 1.8 seconds. If you eat incorrectly, you lose "DPS uptime," making the fight longer and causing you to take more total damage. Sometimes, NOT eating is the most efficient survival strategy.

3. The Cost of Survival: GP per Hitpoint

If you are training Slayer, using high-end food like Manta Rays is a waste of money. Scenario: You need to heal 1,000 HP during a Dragon task. - Using Manta Rays: 1,000 HP / 22 = 45 fish. Cost: ~90,000 GP. - Using Potatoes with Cheese: 1,000 HP / 16 = 63 spuds. Cost: ~25,000 GP. You save 65,000 GP per hour by using slightly less efficient food. Over a month of playing, this can easily add up to 20 or 30 million GP—the cost of a major gear upgrade like a Zulrah Blowpipe or Amulet of Torture.

4. Special Food: Anglerfish and Over-healing

Anglerfish are unique because they can boost your health above your maximum level. At 99 Hitpoints, an Anglerfish can boost you to 121 HP. Strategy Pro-Tip: Always "Angler Up" at the bank before starting a boss trip. Those extra 22 HP can often be the difference between surviving a massive combo or seeing the "You have died" message on your screen. Our tool calculates your "Max Boosted HP" based on your current level.

5. Gielinor's Best Value: The Karambwan Meta

The **Cooked Karambwan** (from the Tai Bwo Wannai Trio quest) is arguably the best food item in the game. Why? 1. It has a shorter attack delay (2 ticks instead of 3). 2. It can be combo-eaten with anything. 3. It is relatively cheap to buy and easy to fish. Our calculator consistently ranks the Karambwan as the highest "Practical Efficiency" food for mid-to-high level players.

6. Ironmen Survival: Sourcing Efficient HP

For Ironmen, fish like Sharks are a mid-to-late game luxury. Early on, the Warriors' Guild Food Shop (selling Potatoes with Cheese) is the most time-efficient way to get high-healing supplies. Later, Minnow Fishing provides thousands of Sharks per hour. Use our tool to compare "Hours spent Fishing" to "Hours of Combat sustained" to find the most efficient path for your account.

7. The 2026 PvP Perspective

In PvP, healing isn't about sustainability; it's about **Reaction Time**. Every millisecond counts. Our tool includes a **PvP Threshold Calculator** that tells you which food you need to stay out of "G-Maul Special" range. Know your opponent's max hit and ensure your HP is always 1 point higher than their maximum possible combo.

8. Conclusion: Eat Smarter, Not More

Don't just click food; understand the math behind the bite. Whether you are aiming for a sub-30 minute Inferno or just trying to save some gold on your Slayer task, the OSRS Food Consumption Calculator is your roadmap to efficiency. Optimize your inventory, master your combo-eating, and keep your Hitpoints high without breaking the bank.
