Green Cemetery Calculator

Natural burial space and biodegradable options.

About this calculator

This calculator prices out a green burial and sizes how many of them a parcel of land can hold. Land capacity comes from treating each grave as an 8x3.5 ft footprint padded on all sides by your chosen plot spacing, then fitting that unit into 70% of the entered acreage — the other 30% is set aside for paths, meadow, and unmanaged buffer, which is typical for natural burial grounds that deliberately skip manicured turf. The cost side adds up six line items per burial: a $2,000 plot, container cost (a $400 shroud, $1,200 biodegradable casket, or $2,500 wicker casket, selectable), $800 for grave opening/closing without a vault, a $150 GPS-coordinate marker in place of a headstone, $500 for embalming-free body preparation, and an optional $350 memorial tree.

That total is compared against a traditional burial built from separate fixed averages — casket, vault, embalming, plot, opening/closing, and headstone — to show a dollar and percentage savings. The tool also reports two environmental proxies: gallons of formaldehyde avoided (a flat 3 gallons per burial) and pounds of concrete vault material avoided (a flat 3,000 lbs per burial), both simple multipliers rather than site-specific measurements. Because every cost is a fixed national average rather than a regional quote, treat the dollar figures as planning-level estimates — actual green burial costs vary significantly by state, cemetery, and container sourcing, and land-capacity numbers assume a rectangular, obstruction-free burial field.

How to Use This Calculator
  1. Enter cemetery acreage and plot spacing in feet (green cemeteries typically space graves 6–12 ft apart).
  2. Select container type: shroud, biodegradable casket, or wicker/willow.
  3. Enter number of burials and whether to include a memorial tree.
  4. Review Cost per Green Burial, Total Green Cost, Savings vs. Traditional ($), and Savings (%).

What each input means

Cemetery acreage
Total land area in acres for the green cemetery.
Plot spacing (ft)
Distance between graves in feet (green cemeteries typically use 6-12 ft).
Container (0=shroud, 1=bio casket, 2=wicker)
0 = shroud ($400), 1 = biodegradable casket ($1,200), 2 = wicker/willow ($2,500).
Number of burials
How many green burials to estimate.
Memorial tree (0=no, 1=yes)
Plant a memorial tree at the gravesite ($350).

What each result means

Cost per green burial ($)
Total cost of one green burial including plot, container, and services.
Total green burial cost ($)
Combined cost for all requested burials.
Traditional burial cost ($)
Equivalent cost if using traditional burial for comparison.
Savings vs traditional ($)
Money saved by choosing green burial over traditional.
Savings %
Percentage saved compared to traditional burial.
Max plots on acreage
Maximum burial plots that fit on the land with current spacing.
Container cost ($)
Cost of the selected burial container type.
Formaldehyde avoided (gal)
Gallons of formaldehyde-based embalming fluid not used.
Concrete avoided (lbs)
Pounds of concrete vault/liner material avoided.
Memorial trees planted
Number of memorial trees planted at gravesites.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Cemetery acreage = 5, Plot spacing (ft) = 8, Container (0=shroud, 1=bio casket, 2=wicker) = 1, Number of burials = 1 = 5 input(s) provided
  2. Calculate Cost per green burial
    Cost per green burial = plotCost + containerCost + openingClosingCost + gpsMarkerCost + treePlantingC...
    5000 = $5,000
  3. Calculate Savings vs traditional
    Savings vs traditional = totalTraditionalCost - totalGreenCost
    7000 = $7,000
  4. Calculate Total green burial cost
    Total green burial cost = perBurialCost * numberOfBurials
    5000 = $5,000
  5. Calculate Traditional burial cost
    Traditional burial cost = traditionalPerBurial * numberOfBurials
    12000 = $12,000

Frequently Asked Questions

Why does the calculator use 70% of the acreage for burial plots instead of the full parcel?

Green burial grounds intentionally keep a large share of land as unmanaged meadow, native plantings, and walking paths instead of dense rows of graves — that's part of what makes them 'green' rather than a lawn cemetery with a smaller footprint. The calculator reserves 30% of your entered acreage for that buffer and only tiles graves into the remaining 70%, so raising total acreage increases plot capacity roughly in proportion but never uses the whole parcel.

How is the maximum number of plots on my land calculated?

Each grave is modeled as an 8x3.5 ft footprint, then padded on every side by your chosen plot spacing (4-20 ft) to get a total unit size. The calculator divides the usable burial area (70% of total acreage, converted to square feet) by that padded unit area and rounds down to a whole number of plots, so tighter spacing always yields more plots per acre than wider spacing.

Why is the shroud option cheaper than the biodegradable casket, and how much does container choice affect total cost?

A shroud is just fabric wrapping, so it carries a flat $400 cost, versus $1,200 for a cardboard or softwood biodegradable casket and $2,500 for a wicker/willow casket. Container cost is only one of six line items in the per-burial total (plot, container, opening/closing, GPS marker, body prep, and optional tree), so switching from wicker to shroud saves $2,100 per burial but doesn't change the plot, marker, or preparation costs.

Are the formaldehyde and concrete savings figures based on my actual burial details?

No — they're flat per-burial multipliers, not measurements tied to your specific container or plot choice. The calculator assumes every avoided traditional burial skips about 3 gallons of embalming fluid and about 3,000 lbs (1.5 tons) of vault concrete, then multiplies those constants by your number of burials, regardless of which container type you selected.
