Annual Maintenance Budget Rules of Thumb
Budget these percentages of the New Replacement Value (NRV) annually for maintenance (parts + labor).
| Machine Type | Annual Budget (%) | Example ($100k Machine) | Notes |
|---|---|---|---|
| Standard 3-Axis VMC | 2.0% - 3.5% | $2,000 - $3,500 | Simple mechanics. Reliable. |
| 2-Axis Lathe | 2.5% - 4.0% | $2,500 - $4,000 | Box ways require more lube/maintenance. |
| 5-Axis / Mill-Turn | 4.0% - 7.0% | $4,000 - $7,000+ | Complex heads, more sensors, more crashes. |
| Grinders | 5.0% - 8.0% | $5,000 - $8,000 | Abrasive environment destroys ways/seals. |

Labor (Alignment critical!)
Hourly Service Labor Rates (USA)
| Independent Technician | $95 - $140 / hr | Lower overhead. Variable skill. |
| Distributor Service (OEM) | $150 - $225 / hr | Factory trained. Warranty support. |
| Specialist (Laser/5-Axis) | $250 - $400 / hr | Calibration & metrology experts. |
Don't forget Travel Expenses. Most OEMs charge $1.50 - $2.00 per mile + Hotel + Per Diem. A simple 1-day repair often costs $2,500+ when travel is added.
