AMs approved the assembly commission's draft budget for 2011/12 on 8 December 2010.
Currently, the commission's £46m budget makes up 0.3% of the Welsh block grant the assembly receives from the UK government.
The commission's strategy for the next four years is to deliver savings at least equivalent to the estimated percentage reduction in the Welsh block over the same period.
Despite this, the budget for next year will increase in cash terms because assembly expenditure in an election year is necessarily higher to reflect the costs of AMs who stand down and are not returning.
It is estimated that total one-off costs for the election will stand at over £3m.
The actual costs of the election will depend upon the circumstances of individual new and departing AMs and on the level of change in assembly membership.
William Graham AM, the Conservative representative on the assembly commission, thanked the members of the finance committee for their recommendations and support.
