Aquarium setup cost calculator

Enter your own purchase amounts and supplies. Initial equipment, recurring costs and electricity stay separate.

One-time purchases

Leave a line blank if you don’t know the price yet; enter 0 if you don’t need it. These are your prices, not a shop’s.

A recurring supply

Use a replacement pack, reagent, conditioner or other recurring item. Follow its actual use or manual, not a universal replacement schedule.

Estimate annual electricity →

Add other purchases

Keep these out of the grouped amounts above to avoid counting them twice.

A copied link contains your amounts. Only share it with people you want to see them.

Start with the essentials

A box that contains a filter may not contain every accessory needed to run it. Air-driven sponge filters need an appropriate air source and tubing. External filters need space for hoses and maintenance access. Lights may need a suitable mounting arrangement.

Build your list from a tank equipment checklist, then enter the cost of the exact items you choose. Supplies consumed by water changes or tests belong in the recurring section. Reusable filter media should not inherit a disposable-cartridge schedule.

Costs alone cannot decide which equipment fits. Check the fit notes on each model page before swapping in cheaper parts.
