If you mean in RuneScape, it is not much less than from 1-99 - about 13 million. To get a more exact figure, you can do one of the following:
1) Search an online RuneScape guide, for example runescape.wikia.com, for "Experience". You'll find tables telling you how much experience is required for each level.
2) Pressumably you have a skill at level 76. Set the objective (by right-clicking on the skill) to level 99; if you then move your mouse over the skill, it will tell you how much experience points you still need. This is faster than the first method; also, it takes into account your exact experience points (for example, you may actually already be close to level 77).
