Prayer Calculator (OSRS)



Welcome to my Prayer Calculator for OSRS. Here you can find out how many bones you need for a certain goal e.g. level 99, 200M XP. It has the ability of fetching your Prayer Level and XP from the OSRS Hiscores. Down below this calculator is a Price Calculator which calculates how much money you need for the bones. It has the ability to fetch the bones price from the OSRS Grand Exchange. Best of luck with your Prayer goals!



  • Credit to @Im Dakota for assisting me during the early stages of this calculator.
  • You can choose to do either Current Level or Current XP, and either Level Goal or XP Goal.
  • You save on average half the amount of bones when you're using the Chaos Altar.
  • The Gilded Altar alone gives 250% Bonus XP. Each burner (incense, mahogany, or marble) provides an additional 50% Bonus XP. Overall, it's 350% Bonus XP.
  • Level 127 is 200M XP for this calculator.
