OSRS tools
Everything on OSRS Helper that does something rather than explains something. Free, no account required.
Live
Working tools
Built and usable now. Those marked with live prices read the current Grand Exchange rather than stored figures.
Quest Planner
Enter your levels and see which quests you can start now, and what is blocking the rest.
Checks every quest we cover against your stats, your completed quests and your quest points, and names the specific requirement missing rather than just refusing.
Max Hit Calculator
Your exact max hit for melee, ranged and magic, using the game's own formula.
Accounts for prayer, attack style, void, potions and the damage multipliers, and floors at every step the way the game does — which is why the answer matches in game rather than being one off.
GE Profit Calculator
Work out net profit on a flip after the 2% Grand Exchange tax.
Enter a buy price, sell price and quantity to see gross profit, tax charged, net profit, ROI and the capital the trade ties up.
GE Tax Calculator
See exactly what the Grand Exchange takes from a sale.
Shows the tax on a single sale, including the per-item cap and the exemptions, plus the break-even price you need to sell at to avoid a loss.
XP Calculator
Experience remaining to your target level, and how many actions that takes.
Works from either level or exact experience, and converts the remainder into actions at whatever rate you enter.
Combat Level Calculator
Calculate combat level and see which stat raises it next.
Uses the standard Old School combat formula and tells you the cheapest single stat increase that would push you into the next combat level.
Drop Rate Calculator
The real odds of seeing a drop across a number of kills.
Calculates the probability of at least one drop over N attempts, the odds of going dry, and the kill counts at which you pass 50%, 90% and 99%.
Prayer Calculator
Bones needed and GP cost to reach your Prayer goal, at live prices.
Compares every bone against every altar multiplier, so you can see how many you actually need before committing to a route.
Herblore Calculator
Every potion ranked by cost per experience point.
Prices each potion and herb against the live market, including what the finished product sells back for.
Crafting Calculator
Battlestaves, dragonhide, glass and jewellery, costed per XP.
Smithing Calculator
Bar and item smithing costs at current ore and coal prices.
Cooking Calculator
Raw against cooked prices for every food worth training on.
Fletching Calculator
Bows, bolts and darts ranked by cost per experience point.
Construction Calculator
What each plank method costs, at today's plank prices.

Build a loadout and see the combined bonuses.
Loot Tracker
Log drops over a session and value them automatically.
How we build tools
Every tool here shows its working. Where a result comes from a game formula, the formula is on the page. Where it comes from market data, the data carries a timestamp and a source. You should be able to check any number we give you.
Nothing requires an account and nothing is held back behind a signup. If a calculator answers your question and you leave, that is the page having worked.
The roadmap above is honest about what does not exist yet. We would rather list six working tools and six planned ones than present twelve as though they all work.
Suggest a tool
If there is a calculation you keep doing by hand, we would like to know. The tools on this list started as exactly that.
