Herblore Calculator
Herblore in Old School RuneScape rewards planning more than almost any other skill. Every potion needs supplies bought or gathered in advance. Guessing wrong means a half-finished grind and a drained coin pouch. A herblore calculator turns your goal into hard numbers before you spend anything. Enter your current experience, pick a target level, and choose a training potion. The tool tells you exactly how many potions stand between you and that level. Add a supply cost and it also prices the whole grind.
Veterans treat this skill as a budgeting exercise disguised as potion making. The players who reach 99 smoothly almost always planned the route first. They knew their potion counts, their costs, and their stopping points.
This guide explains the thinking behind those numbers. You will learn how Herblore experience works, which milestones matter, and how players compare fast methods against cheap ones. Two worked examples follow the calculator step by step. A short set of training tips finishes the guide.
What Is Herblore in Old School RuneScape
Herblore is the potion-making skill, and it is members only. The Druidic Ritual quest unlocks the skill for new accounts. Finishing that short quest also grants enough experience to reach level 3. From there, training follows one simple loop. You clean a grimy herb, add it to a vial of water, and finish the potion with a secondary ingredient.
Each finished potion grants a fixed amount of experience. Attack potions give a modest 25 experience each. Saradomin brews, far up the ladder, give 180 experience each. Herbs come from Farming, monster drops, and the Grand Exchange. Secondaries range from cheap shop stock, like eye of newt, to gathered items like snape grass. Because supplies cost coins or time, the potion count is the heart of every training plan.
Most beginners meet the skill right after the quest, mixing attack potions at a crowded bank. The rhythm never really changes as levels rise. Only the ingredients grow rarer and the experience per potion grows larger. That steady loop makes Herblore easy to plan precisely.
How Herblore Experience and Levels Work
Levels in Old School RuneScape follow one shared experience table. Every level needs more total experience than the one before it. Level 10 sits at 1,154 total experience. The level 50 mark requires 101,333 experience in total. Level 99 demands 13,034,431 experience, a figure every veteran knows by heart.
The growth curve surprises new players most at the halfway joke. Level 92 is only halfway to 99 in experience terms, despite looking close. Its threshold of 6,517,253 experience is half of the level 99 total. Planning by level alone therefore misleads badly. Planning by experience is exact, which is why the calculator asks for your current experience. Cleaning herbs grants experience too, yet nearly all progress comes from finishing potions.
Quest rewards can skip some of the early climb. Several short quests hand out Herblore experience lamps or direct rewards. The remaining distance to any target is simple subtraction. The calculator performs that subtraction against the official thresholds, then divides by your chosen potion.
How to Use the Herblore Calculator
Your exact experience total is the only figure you need to look up. Hover over the Herblore icon in your skills panel, or check your account on the hiscores.
- Find your current Herblore experience and type it into the first field.
- Choose the level you want to reach from the target list.
- Pick the potion you plan to make from the method list.
- Optionally enter what one potion costs you in supplies.
- Press Calculate and read the potion count and totals.
Try a second method before you commit any coins. Switching the potion choice takes two seconds. Comparing two or three methods side by side is the cheapest research in the game.
One caution deserves repeating before the examples. The calculator counts experience for whichever potion you select. It cannot stop you picking a potion your level has not unlocked yet. Check the level shown beside each method name. If that number sits above your current level, pick a lower method instead.
Worked Example 1: First Levels With Attack Potions
The Inputs
Imagine a brand new account that just finished Druidic Ritual. Its Herblore experience starts at zero for this example. The goal is a modest level 10. Attack potions are the natural method, since they unlock at level 3 and use cheap supplies. Each one grants 25 experience. Guam leaves and eyes of newt keep the shopping list painless.
The Calculation
The calculator looks up the experience needed for level 10. That threshold is 1,154 experience. Subtracting the current zero leaves the full 1,154 still to earn. It then divides 1,154 by the 25 experience per attack potion. The raw answer is 46.16 potions. Nobody can mix a fraction of a potion, so the count rounds up to 47.
The Result
Forty-seven attack potions carry the account from no experience to level 10. The final potion overshoots the threshold slightly, which is normal. Small overshoots appear at almost every target. Early levels feel fast because the thresholds are tiny. The same method would crawl later, which is why players switch potions as they climb.
Buying supplies for this whole example takes one quick bank trip. Inventory space limits each run to a small batch of potions. Even so, the plan finishes inside a few relaxed minutes. That speed is why early Herblore feels friendly compared with the higher levels.
Worked Example 2: Saradomin Brews From Level 50 to 60
The Inputs
Now picture an established account sitting exactly at level 50. Its experience total is 101,333, the level 50 threshold. The goal is level 60. Saradomin brews are the chosen method at 180 experience each. For the cost side, suppose supplies for one brew run 9,000 coins.
The Calculation
Level 60 requires 273,742 total experience. Subtracting the current 101,333 leaves 172,409 experience to earn. Dividing that by 180 experience per brew gives about 957.8. Rounding up sets the plan at 958 brews. Multiplying 958 brews by 9,000 coins gives a total supply cost of 8,622,000 coins. Dividing the 9,000 coin cost by 180 experience gives 50 coins per experience point.
The Result
The grind needs 958 Saradomin brews and about 8.6 million coins in supplies. That 50 coins per experience figure is the number worth remembering. It lets you compare brews against any other method fairly. A cheaper potion with a lower cost per point may suit a smaller bank. A faster potion may suit a player short on time instead.
Selling the finished brews claws back part of that outlay too. Brews stay in demand because high-level players drink them constantly. The calculator shows the gross supply cost before any resale. Your real net cost will land lower. Treat the headline figure as a safe worst case for budgeting.
Fastest Methods Versus Cheapest Methods
Every potion takes roughly the same time to mix. Banking speed, not mixing speed, separates most players. Efficient trainers finish around 2,500 potions per hour at a bank. Experience per potion therefore decides the hourly rate almost completely. Saradomin brews sit near the top, with guides commonly quoting 400,000 experience per hour or more at full focus.
Speed, however, usually charges premium prices. Cheap methods trade hours for coins saved instead. Prayer potions have a long reputation for gentle costs per experience point. Super defence potions also stay relatively cheap through the middle levels. The right choice depends on your bank and your patience. Compare methods by cost per experience point, never by the sticker price of a single potion. An amulet of chemistry helps either route slightly, occasionally producing a four-dose potion instead of three.
Many players blend the two philosophies across one grind. They sprint through levels they dislike with an expensive method. Then they settle into a cheaper potion for the long middle stretch. The calculator supports that style well, since each segment takes seconds to replan.
Level Milestones Worth Planning Around
Certain unlocks change both training and everyday gameplay. Prayer potions arrive at level 38 and restore Prayer points during combat. They stay in constant demand forever. Super attack and super strength open at levels 45 and 55, forming the core combat set. Restores follow at level 63, with Sanfew serum close behind at 65.
Super defence unlocks at level 66 and feeds a bigger prize later. At level 90, super combat potions combine the three super potions with a torstol. Saradomin brews at level 81 heal and boost Defence, so players keep them for bossing. Anti-venom+ at level 94 cures venom and serves the Zulrah grind. Planning targets around unlocks turns one grind into several useful rewards.
Milestones also break the road to 99 into kinder pieces. Reaching 38 changes your account immediately, because prayer potions fuel longer boss trips. Hitting 63 does similar work for accounts that live on restores. Each stop on the way pays you back in capability, not just numbers.
Notes for Ironman Accounts
Ironman accounts cannot trade or use the Grand Exchange. Every herb and secondary must be gathered personally. A potion count therefore doubles as a shopping list of raw items. Nine hundred brews means nine hundred toadflax and nine hundred crushed nests, gathered one by one.
Some methods suit that lifestyle better than others. Eye of newt sells cheaply in shops, so attack and super attack potions stay friendly. Snape grass can be collected in bulk on Entrana or grown. Super combat potions demand the three super potions first, all made by hand. Sanfew serum asks for nail beast nails from Temple Trekking. The calculator still helps ironmen, because counts matter more when nothing can be bought.
Farming timers shape the ironman version of every plan. Herbs grow in real time, so supply arrives in waves between other activities. Most ironmen therefore train Herblore in bursts whenever a harvest lands. Knowing the exact potion target in advance tells them when a wave is worth processing.
Tips for Smarter Herblore Training
Good habits stretch both coins and patience across a long grind.
- Check your exact experience on the hiscores before planning any long session.
- Buy unfinished potions to skip the herb and vial step entirely.
- Sell finished potions as you go, recycling coins into the next batch.
- Train toward an unlock you will actually use, like prayer potions at 38.
- Recheck supply prices before big purchases, since small shifts move big totals.
- Keep some useful potions for your own bossing instead of selling everything.
- Split a huge goal into level-by-level targets to keep motivation steady.
Frequently Asked Questions
General Questions
1. What does the Herblore Calculator do?
It works out how many potions you need for a target level. Enter your current experience, choose a goal, and pick a potion. The tool returns the experience remaining and the potion count. A cost field adds total coins and cost per experience point.
2. Where can I find my current experience?
Hover over the Herblore icon in your skills panel to see your exact total. The official hiscores list it too, once your account ranks. Use the full experience number, not just your level. Two players at one level can be far apart in experience.
3. Does this calculator work for RuneScape 3?
No, the values here belong to Old School RuneScape only. The newer game uses different potions, different experience awards, and extra tiers beyond these recipes. Mixing the two sets of numbers would produce wrong counts. Always plan with the version you actually play.
4. Is Herblore a members only skill?
Yes, Herblore requires a membership subscription. You must also complete the Druidic Ritual quest before training it. That quest is short and grants enough experience for level 3. Attack potions become available right away at that level.
5. Why does it ask for experience instead of level?
Levels hide your real progress inside them. One level 50 player might sit exactly on the threshold, while another is nearly at 51. Experience gives the calculator an exact starting point. That precision keeps the potion count honest.
How the Calculation Works
6. How does the calculator know the experience for each level?
It builds the official experience table from the standard formula the game uses. Each level sums the requirements of every level before it. Level 99 lands on the familiar 13,034,431 total. Targets therefore match the game exactly.
7. Why is the potion count always rounded up?
You cannot make a fraction of a potion. A raw division like 46.16 means the final potion carries you past the line. Rounding up guarantees the plan actually reaches the target. The small overshoot is harmless extra experience.
8. What does GP per XP mean?
It divides the supply cost of one potion by the experience that potion grants. A 9,000 coin brew at 180 experience costs 50 coins per point. Lower figures mean cheaper training. Use it to compare methods with different prices and experience values.
9. Does cleaning herbs count toward the total?
Not in this calculator. It counts experience from finishing potions only, matched to the method you selected. Cleaning grimy herbs grants small separate experience in the game. Treat any cleaning gains as a tiny bonus on top of the plan.
10. Why is level 92 called halfway to 99?
The experience curve bends steeply upward at high levels. Level 92 needs 6,517,253 experience in total. Level 99 needs 13,034,431 experience, almost exactly double. So the second half of the levels holds as much work as the first ninety-two combined.
Practical Questions
11. Which potion is the cheapest way to train?
Prices move daily, so no single answer stays true forever. Prayer potions and super defence potions often post low costs per experience point. Enter current supply prices for two or three methods and compare the figures yourself.
12. Which potion is the fastest way to train?
Saradomin brews grant 180 experience each, the highest among standard single potions here. At fast banking speeds they pass 400,000 experience per hour. Super combat potions also train quickly but need three super potions per batch.
13. What if my chosen potion unlocks above my level?
The game will not let you make that potion yet. Choose a method at or below your current level instead. The calculator counts experience for whichever potion you select. It cannot check unlock requirements against your account for you.
14. Should I sell the potions I make?
Selling usually offsets a healthy share of the supply cost. Prayer potions, super sets, and brews all enjoy steady demand from combat players. Keeping some for your own bossing is equally sensible. Decide based on whether your next goal needs coins or supplies more.
15. Do the GP figures update with live market prices?
No, the cost field uses whatever figure you type in. Grand Exchange prices shift constantly, so a built-in price would age badly. Check current prices before a long grind and enter a fresh number. Your totals then reflect the market you are actually buying in.
CONCLUSION
A herblore calculator converts a vague goal into an exact shopping list. Experience remaining, potion counts, and cost per point all follow from three quick entries. Pick a method your level allows, compare its cost per point, and grind with confidence. Level 99 stops feeling distant once it has a number.
