Tip: if you don’t know your prices, call one supplier and ask for “refill price for customer-owned” and “exchange/swap price.” People say “we don’t refill” when they mean “we only exchange.”

“Cheaper” isn’t always “better.” Exchanges are often faster and easier. Refills can be cheaper and keep your cylinder. This tool just makes the trade-off obvious.

How to use this tool

If you want the simplest answer

  1. Enter refill price, exchange price, and how many times per year you’ll need CO2.
  2. Optionally add your trip cost if one option typically takes more visits or extra driving.
  3. Use the output: it shows yearly totals and which option wins.

If you want accuracy

  • Use your real prices (they vary a lot by region).
  • Refill can be “while-you-wait” or “drop-off.” Exchange is usually immediate.
  • Some places only refill “in-date” cylinders. That policy can change the true cost.

Real-world notes that matter

Exchange is convenience

Swaps are usually fast and predictable. The trade-off is you might not keep “your” cylinder.

Refill can be cheaper

Some suppliers price refills lower, especially for larger cylinders. But refill policies vary and sometimes take longer.

Policies change the math

If a shop only refills “their” cylinders or requires test dates, that can push you toward exchange or a different supplier.

If you’re building an aquarium or homebrew setup, a common “easy mode” path is: standard cylinder + exchange supplier. If cost matters later, optimize to refills once you know your local options.

FAQ

Why add “trip cost”?
Because the real cost isn’t just the receipt. If refills require a longer drive, drop-off, or extra visit, that time adds up. Trip cost is a simple way to account for that without pretending we know your life.
Is refill always cheaper than exchange?
Not always. Some areas price exchange competitively, and the time savings can outweigh small price differences. This tool shows your break-even point so you can decide quickly.
What if I don’t know how many times per year?
Start with a guess (4, 6, 12). If you want to get fancy, use your cylinder size and typical usage patterns, but most people just need a ballpark decision.
