Annual Maintenance Budget Rules of Thumb

Budget these percentages of the New Replacement Value (NRV) annually for maintenance (parts + labor).

Machine TypeAnnual Budget (%)Example ($100k Machine)Notes
Standard 3-Axis VMC2.0% - 3.5%$2,000 - $3,500Simple mechanics. Reliable.
2-Axis Lathe2.5% - 4.0%$2,500 - $4,000Box ways require more lube/maintenance.
5-Axis / Mill-Turn4.0% - 7.0%$4,000 - $7,000+Complex heads, more sensors, more crashes.
Grinders5.0% - 8.0%$5,000 - $8,000Abrasive environment destroys ways/seals.
