The short answer
Switching completely from smoking to vaping can reduce spending, but there is no honest universal annual saving. Your result depends on the cigarettes or tobacco you actually buy, how much you smoke, the vaping format you use, liquid or pod consumption, replacement parts, setup cost, delivery, and any cigarettes that continue after the switch.
Calculate smoking and vaping separately from your own receipts. For factory-made cigarettes, annual smoking cost is cigarettes per day divided by cigarettes per pack, multiplied by pack price and 365.25. First-year vaping cost is the one-off setup plus twelve months of liquid or prefilled pods and replacement parts. Subtract vaping from the cigarette spend that genuinely stops. For comparisons after 1 October 2026, use expected duty-era shelf prices rather than adding the statutory vaping duty to a price that already includes it.
Key points
- Use your actual pack, tobacco, liquid, pod, coil, and device prices instead of a national average or retailer promise.
- Separate the one-off setup from ongoing monthly vaping costs so the first year and later years are not confused.
- Subtract only cigarette spending that genuinely stops; partial switching means both smoking and vaping costs continue.
- From 1 October 2026, vaping liquid carries duty of £2.20 per 10ml, but duty is not the same as a guaranteed shelf-price increase.
- Puff counts do not provide a reliable cost-per-cigarette conversion because actual puff duration and consumption vary.
A headline such as “save £5,000 a year” looks precise while hiding nearly every input. It may assume 20 factory-made cigarettes every day, a chosen pack price, no remaining cigarettes, a cheap refillable setup, a fixed amount of liquid, no failed pods, no delivery charge, and no price changes. Change any of those assumptions and the answer changes.
The defensible comparison starts with what leaves your bank account. It distinguishes first-year cost from ongoing cost, refillable liquid from sealed prefilled pods, and a complete switch from dual use. It also keeps money separate from health: spending less does not prove that a device is suitable, and a cost calculator must never estimate the nicotine or product a person needs.

Written explanation and assumptions
Smoking per year: divide cigarettes per day by cigarettes per pack, multiply by the pack price, then multiply by 365.25. Vaping first year: add the one-off setup to twelve times the monthly liquid or pod spend plus the monthly replacement-parts spend. First-year difference: subtract first-year vaping cost from the cigarette spending that stops.
Example formula only: someone smoking 10 cigarettes per day from a 20 pack uses half a pack per day. Multiply 0.5 by the actual pack price and 365.25. Compare that result with the actual or expected setup, liquid or pod, and parts costs. If cigarettes continue, add their cost to the vaping side rather than calling the full smoking total a saving.
The estimate excludes delivery, travel, wasted supplies, offers, price changes, and health effects. For periods after 1 October 2026, use expected duty-era shelf prices. Do not add the statutory duty again if it is already reflected in those prices.
Use the formula that matches what you actually buy
| Comparison point | Inputs required | Calculation | Often forgotten |
|---|---|---|---|
| Factory-made cigarettes | Cigarettes per day, pack size, and the price you pay | (Daily cigarettes / pack size) x pack price x 365.25 | Multipacks, travel purchases, delivery, and days when use rises or falls |
| Hand-rolling tobacco | Four weeks of tobacco, papers, filters, and lighters | Weekly average x 52, or monthly average x 12 | Do not force variable roll-ups into a factory-made cigarette pack formula |
| Refillable vaping | Device, liquid, pods or coils, replacement glass or batteries, and delivery | Setup + twelve months of actual or expected ongoing spend | Failed coils, leaking pods, backup equipment, and unused liquid |
| Prefilled pod vaping | Battery kit plus the exact replacement packs consumed | Setup + replacement-pack price x packs used in the period | Number of pods per pack, mixed-flavour waste, spare batteries, and delivery |
| Partial switch | All vaping costs plus the cigarettes or tobacco still bought | Remaining smoking spend + vaping spend | A reduced cigarette count is not the same as avoided pack purchases |
Important context: Use money paid, not nicotine milligrams or advertised puffs, as the cost input. A puff claim is a laboratory-style reference, not a personal duration guarantee.
Build a cost comparison that survives checking
Freeze the comparison period
Choose four representative weeks or a full month. Do not select an unusually cheap smoking month or an unusually expensive vaping setup week to manufacture the answer you expect.
Record every smoking purchase
Include cigarettes or tobacco, papers, filters, lighters, delivery, and purchases made for convenience. If another person buys some of them, include what was actually consumed only when the aim is personal cost.
Separate vaping setup from consumption
Put the initial device and planned backup in a setup line. Put liquid, prefilled pods, coils, replacement pods, and routine delivery in ongoing lines. This prevents a first-month bill from being repeated twelve times.
Count failures and waste
Include leaked liquid, prematurely replaced parts, incompatible purchases, flavours left unused, and emergency shop prices. These are real costs even when the product was not fully consumed.
Keep duty-era prices in the correct period
For a future comparison after 1 October 2026, use the shelf price expected in that period. Older stock and retailer pricing can make the transition uneven, so do not assume every item rises by the same amount on one day.
Recalculate after the first complete month
Replace estimates with receipts. Show both the first-year result and the ongoing annual result after setup. If cigarettes continue, include them openly and review the quit plan rather than hiding their cost.
What drives cost in reusable vaping formats
| Comparison point | Recurring purchase | Best measurement | Main uncertainty |
|---|---|---|---|
| Open refillable pod or tank | Bottled liquid plus pods, coils, or other replaceable parts | Millilitres actually used and parts actually replaced in four weeks | Consumption, coil life, leaks, liquid type, and device compatibility vary |
| Closed prefilled pod kit | Model-specific replacement pods or refill assemblies | Exact packs bought and pods per pack, not advertised puff count | Personal puffing, unused flavours, proprietary supply, and pack configuration |
| Higher-power refillable device | Liquid, coils, and possibly replaceable batteries | Receipts plus measured liquid use over the same period | Power and inhaling style can change liquid consumption substantially |
Important context: No format is cheapest for every person. A lower unit price can be offset by higher consumption, waste, delivery, or equipment that does not support a complete switch.
What the October 2026 duties change
HMRC states that Vaping Products Duty begins on 1 October 2026 at a flat £2.20 per 10ml, or 22p per ml, on vaping liquid whether or not it contains nicotine. That means the statutory duty associated with 2ml is 44p and with 10ml is £2.20 before considering how VAT and commercial pricing appear in the final shelf price.
The duty is a liability in the supply chain, not a universal instruction that every current retail price must rise by exactly the duty amount on the start date. Existing stock, wholesale arrangements, VAT, margins, promotions, and retailer decisions can affect the observed price. HMRC also provides transition arrangements for older unstamped stock already in retail channels.
Tobacco duty also rises on 1 October 2026. HMRC says the tobacco increase accompanies vaping duty to maintain the financial incentive to choose vaping over smoking. That policy intention does not calculate an individual saving. Use the actual shelf prices available to you, and see our UK vape duty guide and statutory duty calculator for the tax mechanics.
Fix the part of the estimate that is least certain
If you do not know future vaping consumption
Run a low, middle, and high monthly scenario
A range shows how sensitive the result is without pretending that nicotine need or liquid use can be predicted from cigarette count.
Watch for: Replace the range with receipts after a representative month.
If you are partly smoking and partly vaping
Add both costs and calculate only avoided smoking spend
This prevents a reduced cigarette count from being presented as if every former pack purchase had disappeared.
Watch for: Pack purchases can be lumpy, so use a four-week or monthly period rather than one day.
If your result depends on puff count
Replace puffs with packs, millilitres, parts, and receipts
Money paid and product volume are auditable. Advertised puffs depend on a test method and do not predict personal duration.
Watch for: Liquid volume still does not predict nicotine absorbed or whether a device is suitable.
If October 2026 prices are not yet visible
Keep tax and shelf-price scenarios separate
The statutory 22p per ml is known, but retailer shelf prices and transition timing are commercial outcomes.
Watch for: Refresh the estimate with real prices after the duty starts.
Questions about smoking and vaping costs
How much does smoking 20 cigarettes a day cost per year?
Multiply the price you pay for a pack of 20 by 365.25. For example, a pack price entered as P gives an annual figure of 365.25 x P. Use your real price rather than a national headline because brands, shops, duty changes, and purchase patterns differ.
How much does vaping cost per year?
Add the one-off device and backup cost to twelve months of liquid or prefilled pods, coils or replacement pods, other parts, and routine delivery. Report the first year separately from later years because setup should not be repeated unless a replacement is genuinely expected.
Is refillable vaping always cheaper than prefilled pods?
Bottled liquid often has a lower unit cost than sealed prefilled pods, but “always” is not defensible. Consumption, coil or pod life, leaks, waste, delivery, device replacement, and whether the setup supports a complete switch all affect the actual result.
Will a 10ml bottle cost exactly £2.20 more from October 2026?
£2.20 is the statutory duty on 10ml, not a guaranteed shelf-price increase for every bottle. VAT, existing stock, supply arrangements, margins, promotions, and retailer decisions affect the final price and when a customer sees a change.
Can puff count show which vape is cheapest?
Not reliably. Advertised puffs depend on a defined machine method, while personal puff length, power, airflow, and use vary. Compare the exact product volume, replacement cycle, and what you actually spend. Our puff-count claim guide explains the limitation.
Does cutting down save the same amount as switching completely?
No. A partial switch can reduce cigarette spending, but both cost streams remain. Add cigarettes still purchased to vaping spend, and count only the smoking purchases that actually stop as avoided cost. For health, keep complete smoking cessation as the goal and use expert support.
