Snowblower vs Plow Cost Comparison Calculator
Compare the true multi-year cost of owning a snowblower against hiring a professional plow service, including equipment, maintenance, fuel, and time value.
### Snowblower Ownership Costs
Snowblower Purchase Price ($)
Annual Maintenance Cost ($/year)
Fuel Cost Per Season ($)
Hours Spent Snowblowing Per Season (hrs)
Your Time Value ($/hr)
Estimated Salvage / Resale Value After Analysis Period ($)
### Plow / Snow Removal Service Costs
Cost Per Plow Visit ($)
Plow Visits Per Season
OR Seasonal Contract Price ($/season, 0 if per-visit)
### Analysis Period
Number of Years to Compare
Annual Discount Rate / Inflation Rate (%) for NPV

#### Formulas Used
Annual Snowblower Operating Cost: Annual Cost = Maintenance + Fuel + (Hours/Season × Hourly Time Value)
Annual Plow Cost: Annual Cost = Seasonal Contract OR (Cost/Visit × Visits/Season)
Net Present Value (NPV) — Snowblower: NPVsnow = Purchase Price + Annual Cost × PVA(r, n) − Salvage / (1+r)n
Net Present Value (NPV) — Plow: NPVplow = Annual Plow Cost × PVA(r, n)
Present Value Annuity Factor: PVA(r, n) = [1 − (1+r)−n] / r (if r = 0, PVA = n)
NPV Savings: Savings = NPVplow − NPVsnow (positive = snowblower wins)
Simple Break-Even Year: Find smallest t where: Purchase + Annual Costsnow × t ≤ Annual Costplow × t
