Many cuts are to come from professional and support areas, while management structures will be streamlined.
BBC director general Tony Hall says this will save around £50m a year so more cuts will come.
Lord Hall said the BBC was facing "difficult choices" because of the tough financial climate.
In announcing more than 1,000 jobs cuts, Lord Hall said he recognised "this is a tough message".
He said the BBC had already made £1.5bn in savings, but because of the shortfall in licence fee income, more needs to be done.
