How to Use This Calculator
  1. Select Project Type (reforestation, avoided deforestation, soil carbon, methane capture, etc.).
  2. Enter Project Area (acres) and Crediting Period (years).
  3. Input Credit Price ($/tCO2e) from current voluntary or compliance market quotes.
  4. Enter Upfront Investment ($) and select the Registry (VCS, Gold Standard, ACR, etc.).
  5. Review Net Annual Credits, Annual Revenue, and Project IRR to assess investment viability.

What each input means

Project type
0 = Reforestation, 1 = Improved forest mgmt, 2 = REDD+, 3 = Methane capture, 4 = Renewable energy, 5 = Soil carbon.
Project area (acres)
Project footprint in acres (for non-land projects, used as capacity proxy).
Crediting period (years)
Duration over which carbon credits can be issued.
Credit price ($/tCO2e)
Expected market price per carbon credit (tCO2e).
Upfront investment ($)
Initial project development, planting, or equipment costs.
Registry
0 = Verra VCS, 1 = Gold Standard, 2 = ACR, 3 = CAR.

What each result means

Net annual credits (tCO2e)
Tradeable credits per year after buffer pool deduction.
Annual revenue ($)
Yearly income from credit sales.
Total lifetime revenue ($)
Total revenue over the crediting period.
Total project cost ($)
All costs: investment, validation, verification, and operations.
Net profit ($)
Total revenue minus total costs over project lifetime.
ROI (%)
Return on investment over the crediting period.
Breakeven price ($/tCO2e)
Minimum credit price needed to cover all costs.
Payback period (years)
Years to recoup upfront costs from net annual cash flow.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Project type = 0, Project area (acres) = 500, Crediting period (years) = 20, Credit price ($/tCO2e) = 15 = 6 input(s) provided
  2. Calculate Net annual credits
    Net annual credits = annualCredits * (1 - bufferPct)
    1400 = 1400
  3. Calculate Annual revenue
    Annual revenue = netAnnualCredits * creditPricePerTon
    21000 = $21,000
  4. Calculate Total lifetime revenue
    Total lifetime revenue = annualRevenue * creditingPeriodYears
    420000 = $420,000
