Experience to next level calculator

Your data

The advancement table is the one from the System Reference Document 5.1, published by Wizards of the Coast under the Creative Commons Attribution 4.0 licence. If your table sits somewhere else, the arithmetic on this page still holds; only the twenty numbers change.

Many tables hand out experience by milestone rather than by monster, in which case the figure to put above is whatever your group actually gains in an evening.

What each level actually costs

Half the levels is nowhere near half the climb. Level ten sits at sixty four thousand of three hundred and fifty five thousand, so arriving at the middle of the sheet means eighteen in a hundred of the journey is done. The shape of the table is why campaigns feel fast for a few months and then seem to stop moving.

The last step is heavier than the first eight put together. Going from nineteen to twenty asks for fifty thousand, while everything up to and including level nine adds up to forty eight thousand. Read the other way round, the whole opening act of a campaign costs less than its final level.

There is also one step that goes backwards, and it is not a mistake in this page. Eleven to twelve costs fifteen thousand while ten to eleven costs twenty one thousand, so the climb briefly gets cheaper. It is the only place in the table where that happens, and it explains a group that spent a long stretch on level ten and then levelled twice in short order.

How much experience do I need for the next level?

It depends far more on where you are than most people expect, because the steps are not the same size. The first one asks for three hundred and the last one asks for fifty thousand.

Put your current total in the box above and the page reads the level off the table for you, then tells you what is missing and how many sessions that is at your rate.

Why does levelling feel so much slower after level ten?

Because it is. Level ten sits at sixty four thousand out of the three hundred and fifty five thousand the whole climb costs, so reaching the middle of the sheet is only eighteen per cent of the journey. Everything after it is the other eighty two.

Put another way, the last step alone costs fifty thousand while everything up to level nine adds up to forty eight thousand. The opening act of a campaign is cheaper than its final level.

Is it true that one level is cheaper than the one before it?

Yes, once, and it is in the official table rather than a slip on this page. Going from eleven to twelve costs fifteen thousand, while going from ten to eleven costs twenty one thousand.

It is the only step in the whole table that gets cheaper, and it explains a group that spent a long stretch on level ten and then seemed to level twice in a month.

My group levels by milestone rather than by experience. Is this page any use?

The shape of the table is still the useful part, because it is what the pace of a campaign was designed around: quick at the start, slow in the teens, heavy at the end.

If you want the session figures as well, put in whatever your group actually gains in an evening and treat it as an average. The arithmetic does not care where the number came from.

Where does the table come from?

It is the character advancement table from the System Reference Document 5.1, published by Wizards of the Coast under the Creative Commons Attribution 4.0 licence, and the attribution is on the page itself rather than only in the code.

If your game uses a different table, everything on this page except those twenty numbers still applies.

How many sessions to reach level twenty?

From nothing at all it is three hundred and fifty five thousand experience, so at a thousand a session that is three hundred and fifty five sessions, and at three thousand a session it is a hundred and nineteen.

That is why most campaigns end somewhere in the teens. Set the target level in the box and the page will tell you the number for where you actually are rather than from zero.
