Tool investment categories

Basic tools (own all):

  • Multimeter
  • Hand tools (wrenches, pliers, screwdrivers)
  • Tape measure
  • Common diagnostic tools
  • Standard for trade

Trade-specific (own most):

  • Per primary trade
  • Daily-use equipment
  • Quality matters

Specialty (selective):

  • Specific high-value work
  • Used occasionally
  • ROI calculation

Premium (selective):

  • Higher quality of basic
  • Long-term durability
  • Personal preference

Tool budget reality

For self-employed tech:

  • Tool investment significant
  • Replace as needed
  • Plan budget

For employee:

  • Sometimes company provides
  • Sometimes personal
  • Mix typical

ROI calculation

Specialty tool considering:

  • Cost
  • Jobs you'll use it on (frequency)
  • Revenue per job
  • Cost vs revenue

Sample:

  • Tool: moderate-cost specialty item
  • Uses per year: 20 jobs
  • Cost saved (vs sub OR rental): meaningful per-job saving
  • ROI: payback in well under a year on the investment

If significantly positive: buy. If marginal: rent OR continue without.

When to rent

Better than buy:
