Unplanned Maintenance Kills The Budget
If you have managed a maintenance or project budget you will have experienced the pressure that unplanned maintenance causes in trying to meet budget. Often a lot of planning has gone into planned activities that are put on hold, whilst money is thrown at unplanned interruptions. It is easy to compile a budget for scheduled activities. But allowing for the unplanned- how do you do that. Most people use experience and make some contingency or have a “bucket” they can draw from. Random failures quite often fall into the category of unplanned failures. But a random failure leading to “Fix on Failure” is a legitimate strategy where monitoring or inspection activities, and redesign/modifications are not applicable.
To predict the amount of resources and budget required for random failures, describe the likely failure rate, and then use a Simulation engine to predict the number of failures expected in a given time frame. You may not know exactly which random failure will occur or when, but you will have resources available to attend to them, without having to “rob” the scheduled work budget.

Fortunately, there are solutions. More and more companies are turning to asset management programs that incorporate preventative maintenance modules. Preventive maintenance may not be the only tool used to address unplanned maintenance issues - but it will allow asset managers to mange their fires instead of constantly battling putting them out.

The problem with failure you have no control when it is going to occur. You can not have a scheduled plan but a ready plan.

What could possibly done would be to classify assets and equipments based on their characteristics like criticality, type and usage etc. and find out mean time between different unplanned events for similar equipments that had occurred in past.
Based on this frequencies and efforts spend during such event check if yu can avoid such event by updating maintenance strategy. If it updated strategies still remains run to fail than work out how many time similar event can occur in future based on factors like age of asset, time since last turn around, estimated utilization etc. Hopefully than you get some indicative figure for budget needed for such unplanned maintenance!!
All this is theoretically possible if you have good amount of accurate historical data!!
Companies that have good procedures will anyway need very small budget for unplanned events!!!

When you have as unplanned breakdown seems like you never have eveything needed to make the repair.

If you think further about this topic we are discussing "How to reduce reactive Maintenance". Yes, I am linking the words "unplanned maintenance" to reactive maintenance. It is certainly true that proactive maintenance is less costly than reactive maintenance.
With that said i think the answer is more involved.
Although a PM program (setup & use) is important it has to be more than that. The goal here is to go after unplanned, unscheduled work, and also, any events which lead to additional O&M costs which could have been avoided. Can I underline that last sentence?
Examples of avoidance are rework; working on the wrong asset; worker delays due to lack of materials; improper planning; improper work prioritzation; inaccurate CMMS data (such as job statuses); lack of failure/problem code history; performing self-imposed emergency work (wonder how often this happens?); no repair/replace criteria leading to extra repair/replace costs; no weekly schedule; no long range plan visibility; too much PM; incorrect PM tasks; PdM on non-critical equipment; no basic failure analysis; unnecessary expediting costs; safety viloations; workers hurt; no clear roles & responsibilities regarding use of the CMMS; no reviews of open maintenance backlog, or PM library or reactive maintenance or recurring failures; poor CMMS procedures; and no CMMS roadmap for continuous and sustained improvement.
These are all costs which I call "Total Cost of Lost Opportunity" - and costs the budgeting folks may never know about (because we didn't tell them about it). They may be just looking at last years budget and adding 10%.
