Vape juice calculator: what does your e-liquid cost?

The short answer: think in per-ml, not per bottle

Bottle prices are misleading because bottles come in wildly different sizes. A 10ml nic salt bottle at $4 is the same per-ml cost as a 50ml short fill at $20, even though one is a fifth of the price. The number that actually predicts your spend is cost per milliliter: divide the price by the bottle size, then multiply by how many milliliters you vape each day.

Most vapers fall in the 3-5ml per day range, which is what makes a $20 bottle last one to two weeks. At that usage the annual juice bill lands between $400 and $700 — before factoring in coils, pods, and devices, which the vaping cost calculator adds in for a complete picture.

Why bigger bottles and DIY win on cost

Buying bigger is cheaper per ml — the 100ml and 120ml bottles in the table halve the per-ml cost of the 30ml size. Going further, mixing your own juice with our e-liquid calculator drops the cost to roughly $0.20-0.35 per ml, because you are buying nicotine shots and base liquid in bulk instead of paying for a bottle, label, and retail margin.

None of this includes the disposable-vape alternative, where a $20 600-puff device effectively charges $1.50-3.00 per ml of liquid. Switching from disposables to bottled juice is usually the single biggest saving available — the smoking cost calculator shows what either habit costs per year when you stack the numbers.
