Nicotine Shot Calculator / Shortfill Calculator

Welcome to Vaping Hardware’s Shortfill / Nicotine Shot Calculator! If you want to know how many Nicotine Shots to add to your e-juice, you’re in the right place!

Just a word of warning… Please be sure to handle your nicotine with care! It’s considered a toxic substance and dangerous if not used with precaution!

New to the concept of Nicotine Shots and Shortfill bottles? No problem, just take a look at our beginners guide to Nicotine Shots and Shortfill E-Liquid…  Also, before you go any further, be sure you know exactly what nicotine strength you need…

If you’ve already settled on a nicotine level, just select ‘Nicotine Shot’ below. Pop in your base nicotine, target nicotine and e-liquid volume and hit calculate. We’ll tell you how many Nicotine Shots to add to your nicotine free e-juice and you’re good to go!

The Nicotine Shot Calculator will also allow you to increase the nicotine strength of your e-liquid. For example, if you want to increase from a 3mg nicotine strength to 6mg, 12mg or more.

If you’ve purchased a Shortfill, select ‘Shortfill’ and input the size of your bottle. For example, a 100ml Shortfill bottle will usually contain 80ml of nicotine free e-liquid. In that case you’d enter ‘100ml’ and hit calculate. Leave the rest up to us and we’ll tell you how much nicotine you need to add to your shortfill bottle to hit your target nicotine strength.

Finally, if you’re a DIY buff and you’re just looking to mix e-juice with your own base liquids, flavor concentrate(s) and freebase nicotine, you’ll want to use our E-Liquid Calculator!

FAQs

A Nicotine Shot is a 10ml bottle of (typically) 18mg strength flavorless nicotine suspended in PG, VG or a mixture of both. In the EU, this is the maximum size and strength of nicotine you can purchase since the introduction of the TPD regulations.

A Shortfill is a bottle of zero nicotine e-liquid with a mixture of PG, VG and flavoring(s) filled to approximately 80% of its volume. Typical sizes are 30ml, 60ml, 100ml and 120ml (be sure to check the total amount of nicotine free e-liquid in your Shortfill bottle!).

If you want to know more, we’ve written a detailed post about Nicotine Shots and Shortfill bottles so be sure to check it out!

It couldn’t be easier to add the contents of your Nicotine Shot to your Shortfill bottle!

Just unscrew the cap of both bottles, carefully pour the contents of your Nicotine Shot into the Shortfill bottle and replace the lid.

Make sure you dispose of the empty Nicotine Shot responsibly and wash your hands thoroughly!

All that’s left to do is give your Shortfill bottle a good shake!

It’s tricky but not impossible! The idea of Shortfill bottles is to leave space in the bottle, allowing you to add your Nicotine Shot(s).

Your Shortfill bottle is filled with PG, VG and flavor concentrate(s) to approximately 80% capacity. Therefore, you only have enough space for a maximum strength of 6mg nicotine before the bottle becomes full.

Achieving a higher nicotine strength would mean either removing some of your nicotine free juice from the Shortfill bottle or adding your nicotine free e-juice to a larger bottle! Either way this increases the space you have available to add Nicotine Shots. However, the drawback is a reduction in flavor…

If you do want to vape at higher than 6mg nicotine strength, it’s actually far easier mixing your own DIY e-juice, which we highly recommend!

We would not recommend vaping a Nicotine Shot straight!

Although it won’t do you any harm, it’s purely just 18mg strength nicotine in either PG or VG. Not only will there be no flavor, it’s also likely to be pretty harsh!

With so many vape retailers offering Nicotine Shots and/or Shortfill bottles, your options are almost endless! Prices and quality can vary considerably, meaning it’s well worth shopping around and doing your research.

However, we’ve personally used and recommend  DarkStar, Just Vape 247 and Vampire Vape!

In most cases you don’t need to steep your Shortfill bottle of e-liquid.  This is because it’s probably had plenty of time to steep before it reaches you! As you’re only adding nicotine to the e-juice, giving it a damn good shake before vaping should mix it thoroughly!

That being said, steeping usually improves the flavor of your e-juice! If you want more info about steeping, check out our steeping guide!

While most nicotine shots will come in a 10ml bottle at a strength of 18mg/ml (damn the TPD restrictions in the EU), you might be one of the lucky ones who have a ‘stash’ of 72mg strength nicotine in the cupboard or happen to live outside the EU.

If this is the case, you can still use your higher strength nicotine to add to a shortfill bottle. Just set your ‘nicotine base strength’ to the correct level and hit the calculate button!

Yes you can, both are great options. Simply input the strength of your nicotine shot and your good to go!

Both forms of nicotine are calculated in exactly the same way.

Yes of course! Your shortfill bottle will contain increased flavor concentrate to compensate when more base liquids are added. So if you don’t vape with nicotine, top up with your required base ingredient (PG/VG) to give you the maximum volume of e-liquid.

We hope you’ve enjoyed using our Nicotine Shot Calculator!

  1. Using 10ml bottles of 18mg/18ml Nic Shots, how many would I have to add to my already 50ml of vape juice that’s already 3mg in strength?

      Hi there,

      Thanks for the message. Unfortunately we can only advise you how many nicotine shots you’d need to add by knowing what strength you want to vape at. However, if you select the ‘nicotine shot’ option on the calculator and input the figures the calculator results will show you how much nicotine you have to add. We hope this helps. Any problems give us a shout.

  2. Hi there, could you please help, Ive purchased120mls of 0% e liquid and some 15mg, 10ml nic shots, I desire to make my liquid 12mg and your calculator said that I need to add 48.0, 10ml bottles… How many bottles is this? Thank you in advance

      Hi Victoria,

      The calculator has correctly worked out that you’d need to add 48 bottles of 10ml nicotine shots (15mg strength). Because the nicotine shots you’re using are not a particularly high strength, the amount you need to add to bring the entire mix to a 12mg strength is very high. Unfortunately adding this amount will heavily dilute the flavour of the juice as well.

      There are only really a few options for you to choose from if you want to vape at 12mg. First you can go down the path of DIY e-liquid mixing using Flavour Concentrates, PG,VG and Nicotine. This is by far the cheapest and in our experience, most enjoyable method.

      Secondly you can buy your e-juice at a pre-made nicotine strength of 12mg. However, this can be costly! The final option could be to look into nicotine salts. They’re becoming much more popular because they allow you to vape at a much higher nicotine strength. We hope this helps Victoria. Any more questions feel free to get in touch.

  3. I think the calculator is incorrect because when I select 50ml shortfill with 0mg nic and the target is 6mg using 18mg nic shots, the result is add 25ml of 18mg nic shots.
    However adding 10ml of 18mg to 50ml of nic free liquid will make it 3mg overall as (10×18)÷50 =3mg. So adding 20ml will make it 6 mg as (20×18)÷50 =6mg. And so the correct answer is 20ml not 25ml

      Hi Mo,

      Thanks for the comment. Sorry to hear you’re struggling with the calculations for adding nicotine to your e-juice. We’ve double checked the figures you’re referring to and we’re confident that our calculator is correct. The problem seems to be the formula that you’re using to get your calculations.

      The correct formula for working out the amount of nicotine shots to add is ‘Target Nicotine ÷ (Nicotine base strength – Target Nicotine) X Amount of E-Juice’. In your case, ‘6 ÷ (18-6) X 50 = 25(ml)’. We know how confusing it can get when it comes to adding nicotine shots to your e-juice. Feel free to check out our post, ‘Nicotine shots and shortfill e-liquid explained‘ for some further information on doing these calculations. Hope this helps Mo 🙂 Any problems feel free to get in touch.

      1. When using the calculator and upping the mg of nicotine. For instance say I want 0.9mg strength it says add 5 10ml nicotine’s but that would make a shortfil bottle to 130m of juice as when buying them there’s 80m in a 100m bottle
        The only way this would be correct is if there was less zero mg in the bottle to start with
        The calculator is just assuming there’s less in the bottle to make it a 100m bottle after adding Nic shots but really when buying them there’s 80 m in them

          Hi Scott,

          Unfortunately this is the problem with shortfill bottles when trying to achieve anything other than a 3mg or 6mg strength. The calculator works correctly and you are also correct in saying that there should be less zero e-liquid in the bottle to start with if you want anything above 6mg.

          When using the ‘Shortfill’ option, our calculator will always work out the correct quantities to prevent you exceeding the bottle size. Use the other drop down option of ‘Nicotine Shot’ to work out the amount of Nicotine to add to your e-liquid to get your desired final strength. Remember though, you will have to decant your e-liquid into a bigger bottle as the results will exceed your shortfill bottle size.

          Hope this helps Scott. Any problems feel free to get in touch.

  4. Hi, I’ve been doing a ton of research on adding nicotine to my current all day vape. I’m a MTL vaper so throat hit is huge for me and my all day vape of 6 years was discontinued. It was 24mg nicotine. My new vape is 18mg nic and I want to be as safe as possible. So much bought 125ml of 100mg nicotine in PG from liquid barn ( nicselect brand). I created a thread on the ecig forum and I’ve got a lot of advice but I feel silly when I have to keep asking how to do this right. Someone gave me the link to your calculator and I think I have it all figured out I just really want to be sure. Long story sorry, so all I want is to make my 30ml bottle of 18mg nicotine into 24mg nicotine. Give or take, it doesn’t have to be exact. With your calculator I did nicotine shot, 18mg base, target 24mg and zero 30ml. I got an answer of 2.37ml to add to my 30ml making it 32.37ml total. So am I correct to say that I will add 2.37ml of my nicotine to my current 18mg 39ml bottle to make it 24mg? God this seems so lengthy and annoying. Any advice would be awesome! Thanks – kelly

      Hi Kelly,

      Don’t worry we completely understand 🙂 You can never be too safe when adding nicotine to your e-juice and it can sometimes get a bit confusing!

      We checked through your figures and you’re spot on! You’ve selected the correct options and the results you have will achieve your desired strength e-juice. With the 100mg nicotine you have, just add 2.37 ml to your existing 30 ml of e juice (18mg) and you’ll have 32.37 ml total e-juice at a 24 mg strength.

      Hope this helps Kelly 🙂 Any problems let us know.
