How to Use the Prayer Calculator OSRS
- Set Current and Target Levels – Enter your current Prayer level (1–99) and your desired target level (must be higher than current).
- Choose Bone Type – Select the bone you plan to use (e.g., Dragon Bones, Superior Dragon Bones). Each bone gives a fixed XP amount shown in the dropdown.
- Select Account Type – Choose Normal or Ironman. Ironman accounts receive only 50% of the bone’s XP.
- Enter Bone Price (Optional) – Input the cost per bone in GP to calculate the total gold cost. Leave at 0 if you don’t need cost info.
- Click “Calculate” – The tool will display:
- Experience Needed – Total XP required to reach your target level.
- Bones Required – Number of bones needed (rounded up).
- Total Cost – Estimated GP cost (if a price was entered).
Tip: All XP values follow the OSRS standard table. Ensure your inputs are whole numbers between 1 and 99. The calculator automatically accounts for the XP difference between levels.

We support Bones, Big Bones, Baby Dragon Bones, Dragon Bones, Wyvern Bones, and Superior Dragon Bones. Each has a different XP value.
The cost is based on the bone price you enter. It multiplies the number of bones needed by the price per bone. You should check current Grand Exchange prices.
