How to use our Wood Stove vs Pellet Stove Cost Calculator
- Enter each full project quote in Wood stove and installation cost and Pellet stove and installation cost. Enter 0 only if that stove is already installed.
- Enter your local Firewood price and Firewood used per heating season, then enter Pellet price and Pellets used per heating season. Use a 40 lb bag price for pellets.
- Open Advanced options to set Years to compare, service costs, and pellet electricity details. Replace the Electricity rate default with the rate from your utility bill when possible.
- Click Calculate. Read Wood cost minus pellet cost after selected years first: a positive amount means pellet costs less, while a negative amount means wood costs less.
- Sanity-check Wood stove recurring cost per year and Pellet stove recurring cost per year against your past receipts. If either fuel price or use is still zero by accident, replace it and calculate again.
Definitions
Cord: A stacked firewood volume measure. It is not a weight.
40 lb bag: The pellet package size used for Pellet price and Pellets used per heating season. Fifty 40 lb bags equal one U.S. short ton.
Recurring cost: A cost that repeats each heating season, such as fuel, service, and pellet electricity.
Installed cost: The one-time project total for the stove and installation work entered in the calculator.
kWh: Kilowatt-hour, the electricity-use unit on an electric bill. One kilowatt equals 1,000 watts.
Cost crossover: The future time when the two cumulative cost estimates are equal under the entered annual costs.
Local fuel price: A price from a nearby seller or receipt. Firewood and pellet prices vary by area and purchase terms, so replace zero starters with local figures. [1]
Common mistakes and quick fixes
Mistake: Comparing Firewood price with Pellet price without using the matching seasonal quantities.
Fix: Enter Firewood used per heating season in cords and Pellets used per heating season in 40 lb bags before comparing costs.
Mistake: Entering only the appliance price in Wood stove and installation cost or Pellet stove and installation cost.
Fix: Use the full project quote, including venting or chimney work, hearth work, labor, and included charges.
Mistake: Leaving Firewood price or Pellet price at zero when fuel is not actually free.
Fix: Replace the zero starter with a current local quote or receipt price. A zero is only appropriate for a cost you intentionally exclude.
Mistake: Using a pellet ignition maximum for Pellet stove average electric draw.
Fix: Use an average operating watt value from the stove label or manual, then enter the expected Pellet stove operating time.
Mistake: Treating a negative Wood cost minus pellet cost after selected years as an error.
Fix: A negative amount means the wood stove costs less by the absolute amount over the selected Years to compare.
Mistake: Forgetting Wood chimney service cost or Pellet stove service cost.
Fix: Add the yearly out-of-pocket service cost you want included, or intentionally leave it at 0 if it is excluded.
Limitations & Key Assumptions / Boundary Conditions
- The calculation assumes fuel prices, seasonal use, service costs, electricity rate, wattage, and operating hours stay the same each year.
- It uses nominal dollars. It does not include inflation, financing interest, resale value, tax credits, insurance changes, or the time value of money.
- Firewood quality, pellet quality, weather, home insulation, stove settings, and actual heat demand can change fuel use.
- Pellet electricity is estimated from one average watt value and seasonal operating hours. It excludes fixed utility charges, battery backup, and generator costs.
- A zero entry is allowed for an existing stove, free fuel, self-service, or an excluded cost. Check that a zero was intentional before using the comparison.
- The lower-cost option is only a cost result. It does not compare safety, outage operation, local fuel availability, emissions, comfort, or installation suitability.
Methodology
Cost calculation
The calculator treats installation as a one-time cost. Fuel, service, and pellet electricity are recurring heating-season costs.
wood fuel cost = Firewood price x Firewood used per heating season
pellet fuel cost = Pellet price x Pellets used per heating season
pellet electricity cost = Pellet stove average electric draw x Pellet stove operating time / 1000 x Electricity rate
wood recurring cost = wood fuel cost + Wood chimney service cost
pellet recurring cost = pellet fuel cost + Pellet stove service cost + pellet electricity cost
wood selected-year cost = Wood stove and installation cost + Years to compare x wood recurring cost
pellet selected-year cost = Pellet stove and installation cost + Years to compare x pellet recurring cost
Wood cost minus pellet cost after selected years = wood selected-year cost - pellet selected-year cost
How to read the gap
A positive cost gap means pellet costs less. A negative cost gap means wood costs less. The calculator compares unrounded totals, so rounding displayed dollars does not change the lower-cost option.
Worked example
If wood installation is $5,000 and recurring wood cost is $1,600 per year, its 10-year cost is $21,000. If pellet installation is $6,000 and recurring pellet cost is $1,336 per year, its 10-year cost is $19,360. The cost gap is $1,640, so pellet costs less over 10 years.
Future crossover
crossover years = (Pellet stove and installation cost - Wood stove and installation cost) / (wood recurring cost - pellet recurring cost)
A future crossover is shown only when the result is zero or greater and annual recurring costs differ. If recurring costs are equal, different installed costs never catch up. The method holds the entered annual values constant and does not model price changes or financing.
