Planning tools for aftercare at zoos, sanctuaries and rehab centers
Ashes weigh roughly 3-5% of body weight[1], a large chamber burns about 250 lb/hour[2] (one manufacturer's rating), and composting a big herbivore can take months. These tools turn numbers like that into a plan your team can budget for.
- Six calculators, no sign-up
- Ranges with sources, not sales figures
- Useful for protocols, budgets and board papers
Before you start
Why institutions use calculators before they call anyone
Most aftercare decisions at a zoo are made twice: once in a planning meeting, calmly, and once on the day, under pressure. The tools here are for the first meeting. They give ranges your team can put into a protocol, a budget line or a note to the board, so that on the day, nobody has to guess what a 700 lb animal will cost or how much ash to expect.
Each tool shows its assumptions and sources. None of them replaces a written quote, and they can't know your local provider's capacity or your state's rules. When you have a number you can work with, send us the details and we'll look for providers who can make it real.
Tool 1
Cremation cost calculator: a first price range by size and type
Enter a weight, the type of cremation and your country, plus extras like after-hours collection. For small and mid-size animals, it draws on published pet cremation price bands. For heavier animals, the useful benchmark is equine: about $0.80/lb[3] at the midpoint, which is our estimate from published horse cremation costs.

Cremation cost calculator
Estimate a realistic price range for your pet's size, location and the type of cremation.
Use it to set a budget band for each weight class in your collection. The full cost calculator page explains how the ranges are built and where they break down for megafauna.
Tools 2 and 3
Ashes weight estimator and urn size calculator: what comes back
The ashes weight estimator applies the standard rule of thumb, 3-5% of body weight[1], to your animal's weight. That's mostly bone, so animals with heavy skeletons return more and those with a lot of soft tissue or fat return less. For a 250 lb tiger, expect somewhere near 8 to 12 lb.

Ashes weight estimator
See roughly how much ash to expect back, by species and body weight.
The urn size calculator turns weight into volume, with room for keepsake portions if keepers or a donor want a share. For large animals, the answer is often that no single urn fits, and a scattering or garden interment makes more sense. Try the urn size calculator with your own numbers.
Tool 4
Aftercare options compared: weighing cost, ashes, speed and impact
Set sliders for what your team cares about most, such as returning ashes, cost, speed, environmental impact or a ceremony, and the tool ranks private cremation, communal cremation, water cremation and burial. It's a useful way to show a committee why a route was chosen.

Aftercare options compared
Compare private, communal and water cremation with burial on cost, timing and what comes home.
Water cremation deserves a closer look for institutions with sustainability goals. A commercial pet system runs for 12–20 hours[4] per cycle at low temperature (one manufacturer's rating). See how it compares on the options comparison page.
Tool 5
Memorial budget planner: plaques, gardens and keeper keepsakes
Memorials usually sit outside the cremation invoice, and often outside the animal care budget altogether. The planner lets you list items with low and high amounts, from a small plaque to a planting or a public event, and gives a running total you can copy into a proposal.

Tool 6
Large-animal mortality planner: capacity for heavy and multiple losses
Built originally for farms, this planner is the most useful tool for institutions with hoofstock or megafauna. Enter the number of animals, average weight and method, and it estimates compost volume, burial pit size or cost range. Composting a mature large herbivore can take around 240 days[5] for the second phase alone, which is worth knowing before anyone suggests it for a bison.
The planner's composting and burial figures follow federal and extension guidance, including the USDA APHIS handout on carcass disposal methods and University of Minnesota Extension's advice on large-carcass disposal. By our estimate, composting a 1,400 lb animal needs roughly 14 to 16.8 cubic yards of cover material[6], which is a lot of wood chips to have on hand. Check local burial and rendering rules on our locations pages before you rely on either route. When the numbers are ready, the services page explains the routes they point to.

Livestock mortality planner
Plan disposal capacity and costs for farm losses, from one animal to a herd.
It's also the right tool for disease planning. If an outbreak meant losing several animals at once, would your provider have capacity? The large-animal planner page walks through a worked example, and our pre-planning guide shows how to turn the answer into a protocol.

Putting them together
A worked planning example: three weight classes, one protocol
Picture a mid-size zoo with a bird and reptile house, a big cat habitat and a small herd of Grevy's zebra. A planning meeting might run the tools like this. For the bird and reptile house, the cost calculator shows that routine losses sit in ordinary pet cremation territory, so a standing arrangement with a local provider and a monthly invoice makes sense.
For a 400 lb tiger, the ashes estimator suggests about 12 to 20 lb of remains, too much for a standard urn, which prompts a conversation about scattering in the habitat or a garden interment. For a 900 lb zebra, the cost calculator uses the equine benchmark, and the large-animal planner shows the one-animal-per-load reality of large chambers: at about 250 lb/hour[2] (one manufacturer's rating), the burn alone takes several hours.
The meeting ends with three lines in the protocol: which provider for each class, what the budget band is, and who signs off. That's the kind of outcome our institutional pre-planning guide is built around, and the cost comparison notes help when quotes come in.

Questions people ask
Are the tool results accurate enough for a budget?
They're good enough for a planning range, not a purchase order. Each tool uses published figures and labels its sources. Real quotes depend on access, distance, after-hours work and paperwork. Use the ranges to set expectations, then ask providers for written totals before committing.
Which tool should a wildlife rehabilitator use first?
Start with the cremation cost calculator for your most common species, which will mostly be small, and then the memorial budget planner if you hold an annual remembrance for volunteers. The large-animal planner matters only if you take in deer, bears or other heavy wildlife.
Can the tools handle an elephant or giraffe?
They'll give you numbers, but treat them with care. Ash weight scales reasonably well, but cost doesn't, because very few providers can take an intact animal of several tonnes and the route often changes to sectioned cremation, digestion or burial. For megafauna, the tools are a conversation starter, not an answer.
Do the tools save or send what I enter?
