> The quit smoking calculator shows how many cigarettes you avoid and how much money you save by quitting – and how much that money could grow to if invested.

## Inputs

- Cigarettes per day
- Cigarettes per pack
- Price per pack
- Time smoke-free (years)
- Expected annual return if invested (%)

## Results

- Cigarettes not smoked
- Money saved per month
- Total money saved
- Value if invested monthly
- Life expectancy regained (≈ 20 min per cigarette)

## Formula

```
Cigarettes avoided = cigarettes per day × days
Money saved = cigarettes ÷ pack size × pack price
Invested value = monthly savings compounded at the expected annual return
```

## Explanation

Quitting smoking is one of the best things you can do for your health, and the savings are large too: a pack-a-day habit at $9 a pack costs over $3,000 a year. A 2024 study from University College London estimated each cigarette shortens life expectancy by about 20 minutes.

### How to use the Quit Smoking and Save Calculator

- **Cigarettes per day**
- **Cigarettes per pack**
- **Price per pack**
- **Time smoke-free**
- **Expected annual return if invested**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter how many cigarettes you smoked per day, the pack size and price, how long you stay smoke-free and an expected return if you invest the savings.

### Tips

- Use the figures from your own bills and product labels – prices and appliance ratings vary widely.
- Look at yearly totals: small daily costs add up and make it easier to compare options.
- Round quantities up to whole packs, rolls or bulbs when you shop.
- Re-check the numbers when prices change; most results scale directly with the unit price.

### Common mistakes to avoid

- Confusing watts (power) with watt-hours or kilowatt-hours (energy).
- Comparing prices without bringing them to the same unit first.
- Ignoring one-off costs such as installation, delivery or replacement parts.

### What each result means

- **Cigarettes not smoked** = [Cigarettes per day]×365.25×[Time smoke-free]
- **Money saved per month** = [Cigarettes per day]×30.44÷[Cigarettes per pack]×[Price per pack]
- **Total money saved** = [Money saved per month]×12×[Time smoke-free]
- **Life expectancy regained (≈ 20 min per cigarette)** = [Cigarettes not smoked]×20÷60÷24

### Example values

How the main result changes when **Cigarettes per day** changes and everything else stays at the example values above:
