Recommended annual maintenance budget = asset replacement value × benchmark percentage (3% by default, adjustable 0.5–15%). The budget is split into five standard categories: preventive maintenance 40%, corrective 30%, predictive 10%, spare parts 15%, and training and other 5%. Optionally you compare it with current spend: below 80% is underfunded, 80–120% matches good practice and above 120% exceeds it.
Example: a replacement value of EUR 2,000,000, 3% and current spend of EUR 45,000 give a recommended budget of EUR 60,000, a shortfall of EUR 15,000 and a ratio of 75%, i.e. “underfunded”.
Frequently asked questions
What is replacement value?
The amount it would cost to replace all the equipment with new equipment.
Does 3% suit everyone?
It is a starting point. With more intensive use or an older fleet you may need more; the benchmark percentage is adjustable.
How should I split the budget?
Use the tool’s standard split and adapt it to the criticality of your equipment fleet.

They are not an engineering calculation, a safety assessment or a substitute for the manufacturer’s instructions, applicable standards or professional judgement. Weights, benchmarks and default values are Maintest planning assumptions and can be adjusted to your situation. Do not use this tool as the only basis for safety-critical decisions such as lifting, electrical work or lockout procedures.
