Create an annual terrarium budget from monthly feeding and substrate costs, equipment electricity, routine annual care, and enclosure equipment spread across its useful planning life. The result converts irregular ownership costs into an annual and average monthly view. Enter your own utility rate and care allowances rather than relying on a generic cost benchmark.
The main result is the annualized ownership cost under the entered assumptions. It includes a yearly share of equipment even though that expense is commonly paid upfront.
Heating equipment may cycle rather than draw rated power continuously. Measure average consumption where possible, and keep emergency veterinary funds distinct if the entered reserve covers only routine care.
At $35/month for food, $18/month for substrate, 75 W for 14 hours/day at $0.18/kWh, a $250 care reserve, and $750 equipment over 5 years: supplies cost $636, electricity $68.99, equipment $150, and total annual cost is $1,104.99.
No. Use it to check arithmetic and planning assumptions, then follow the applicable veterinarian, product label, welfare standard, or qualified care guidance.
A zero is accepted only where it represents no cost, no feed, no water change, or another valid absence. Values used as divisors or required physical dimensions must be greater than zero.
Actual results depend on conditions not fully represented by a compact model, including animal needs, measured consumption, losses, operating practices, and local prices.
Keep the unrounded value for planning. For medication or treatment measurements, use only the rounding and measuring method approved on the label or by the responsible professional.
Update them whenever weight, occupancy, tank volume, husbandry routine, prices, equipment use, or the underlying care plan changes.
| Input type | How to choose it |
|---|---|
| Physical measurement | Use an observed or measured value in the displayed unit. |
| Rate or percentage | Use the applicable care plan, product label, or operating record. |
| Planning period | Keep the period consistent with the formula and result. |
