A 100ml bottle of perfume typically lasts around eight months at four sprays a day, or around 16 months at two sprays a day, based on the common rule of thumb of about 10 sprays per millilitre. That works out at roughly 1,000 sprays per bottle. The real figure depends on your atomiser, because published estimates range from about seven to 20 sprays per ml, so the table below shows a range and explains how to measure your own bottle.
How many sprays are in a 100ml bottle?
There is no single answer, because every atomiser delivers a slightly different amount. Estimates you will see online include:
- about 0.1ml per spray, giving roughly 1,000 sprays in 100ml;
- 0.1 to 0.15ml per spray, giving roughly 670 to 1,000 sprays;
- 0.05 to 0.07ml per spray, giving 1,400 to 2,000 sprays;
- fragrance forum posters who report anything from around seven to 15 sprays per ml depending on the brand and bottle.
Small bottles tend to have smaller nozzles, so a 30ml bottle can deliver more sprays per ml than a 100ml one. For planning, we use three scenarios: a light atomiser (0.07ml per spray, about 1,400 sprays), a typical one (0.1ml, about 1,000 sprays) and a heavy one (0.15ml, about 670 sprays).
How long will a 100ml bottle last?
Approximate months of wear for a full 100ml bottle:
| Sprays per day | Light atomiser (0.07ml) | Typical (0.1ml) | Heavy atomiser (0.15ml) |
|---|---|---|---|
| 2 | about 23 months | about 16 months | about 11 months |
| 4 | about 11.5 months | about 8 months | about 5.5 months |
| 6 | about 7.5 months | about 5.5 months | about 3.5 months |
| 8 | about 6 months | about 4 months | about 3 months |
These are estimates, not guarantees. If you wear a different fragrance each day, a single bottle will last much longer, which is one reason many people build a small wardrobe. Our capsule fragrance wardrobe guide shows how.
What does it cost per spray and per day?
Using the typical figure of 10 sprays per ml and our current prices at the time of writing (15 October 2026), here is how some in-stock bottles compare:
| Bottle | Price | Approx. cost per spray | Approx. cost per day at 4 sprays |
|---|---|---|---|
| Lattafa Qaed Al Fursan 90ml | £12.99 | 1.4p | 5.8p |
| Lattafa Asad 100ml | £22 | 2.2p | 8.8p |
| Lattafa Khamrah 100ml | £25 | 2.5p | 10p |
| Lattafa Emeer 100ml | £29.99 | 3p | 12p |
| Reef 33 100ml | £42.99 | 4.3p | 17.2p |
The 90ml Qaed Al Fursan is calculated on 900 sprays. The point of the table is the scale: even the more expensive bottle here costs well under 20p on a four-spray day. For your own numbers, use our price-per-wear calculator.
How to measure your own bottle
You can find your real spray volume in a couple of minutes.
- The counting method: spray into a small empty container of known size, such as a 10ml decant atomiser, and count how many sprays it takes to fill it. Divide the count by 10 to get sprays per ml. Our decanting guide explains how to handle fragrance safely.
- The weighing method: weigh the bottle on a kitchen scale that measures to 0.1g, spray 20 times, then weigh it again. An eau de parfum is roughly 0.85 to 0.9g per ml, so divide the weight lost by that number to estimate millilitres, then divide by 20 for the volume per spray.
Do this once, in a ventilated space, and you will know whether your bottle is a light, typical or heavy sprayer.
What changes how fast a bottle empties?
- Atomiser design: the nozzle and pump decide how much comes out each time.
- Concentration and formula: thicker, richer formulas can release different amounts per spray.
- Your routine: two sprays on the wrists is a very different rate from four on the neck, chest and clothing.
- Wasted sprays: testing and priming a new pump uses a little.
- Bottle size: smaller bottles can have finer nozzles.
Will it expire before you finish it?
Usually not if you store it well. Many sources suggest sealed bottles can stay good for several years and opened bottles for one to three years or longer, but this varies with the fragrance and, above all, with storage. Heat, direct light and humidity are the main enemies. Our guides to how long perfume lasts before expiring and storing perfume properly cover the details. If you only wear a scent occasionally, a smaller bottle may be the more sensible buy; see our comparison of 30ml, 50ml and 100ml sizes.
How to make a bottle go further without wearing less
- Moisturise first. Fragrance tends to last better on moisturised skin, so you may not need to reapply. See our guide to the right application order.
- Spray the right places. Pulse points work well; see where to spray perfume.
- Use fewer sprays of stronger scents. Rich, resinous fragrances such as Khamrah often need less than light citrus ones.
- Compare value fairly. Our bottle size and value guide and price index show what you pay per ml.

Frequently asked questions
How many sprays are in a 100ml bottle of perfume?
A common rule of thumb is about 10 sprays per ml, which gives roughly 1,000 sprays in 100ml. Real bottles vary, and estimates range from about 670 to 1,400 sprays or more depending on the atomiser.
How long does a 100ml bottle of perfume last at 4 sprays a day?
About eight months using the typical figure of 1,000 sprays. A light atomiser could stretch to roughly 11 months, while a heavy one could be nearer five and a half.
How long does a 30ml bottle of perfume last?
At about 10 sprays per ml, a 30ml bottle gives roughly 300 sprays, or about 75 days at four sprays a day. Smaller bottles can have finer nozzles, so the real figure may be higher.
How much perfume is in one spray?
Most atomisers release somewhere between about 0.05 and 0.15ml per spray, with 0.1ml a common estimate. The only way to know for your own bottle is to measure it.
Is a bigger bottle better value?
Usually the price per ml is lower, but only if you will finish it while it is still in good condition. If you rotate several fragrances or wear a scent rarely, a smaller bottle can make more sense.
