A lot of people new to DIY are overwhelmed. They've heard from person_a to mix up using a specific PG to VG ratio, and person_b to mix up with three different flavors all with different percentages. They've gone out and picked up the supplies, and here they sit in their mixing station wondering how in the world they are going to get everything correct.
The e-liquid calculator is critical to creating e-liquid from base ingredients.
One Stop DIY Shop highly recommends the use of the e-liquid calculator "eJuice Me Up" by Breaktru software. Not only is it free, but the developer is an ECF member. You will find a lot of support for this program as many vapers use it.

For this example, I will be describing the fields that I most often use with eJuice Me Up.
Scenario:
You want to mix up a very small batch of Creamy Strawberry Banana. You've decided that you want the creamy portion to come from Bavarian Cream, and want this to be a heavy taste in your vape. You also decided that you want to have some Strawberry and Banana under-notes to accent the creamy flavor. You've been told that Strawberry and Banana are both very strong flavors, so you decide to work with those in small percentages. You also have heard a lot of people rave about 60/40 blend liquids, and want your final mixture to have 60% PG, 40% VG. You have a Flavor-It-Yourself 48mg 100% PG e-liquid bottle for your nicotine base which you want to dilute down to 12mg, a 4oz mini jug of PG as well as VG, and 6ml bottles of each of the three flavors. You also have an empty 6ml bottle, some 1ml disposable pipettes, and some 3ml disposable pipettes.
Everything is ready to go. Now it's time to make the first experimental mixture. It's time to fill in the areas on eJuice Me Up to receive your calculations.
In the area for Nicotine Strength e-Juice, change PG % to 100, VG will turn to 0. The mg area should be 48. (if you had a Flavor-It-Yourself 48mg 50/50 blend, you would put PG 50%, VG 50%)
Target Nicotine Strength should be 12mg
Amount to Make should be 5ml
Water/Vodka/PGA should be 0
Flavor 1 (type in Bavarian Cream) should be PG 100%, VG will turn to 0. The percentage should be 20
Flavor 2 (type in Strawberry) should be PG 100%, VG will turn 0. The percentage should be 1
Flavor 3 (type in Banana) should be PG 100%, VG will turn to 0. The percentage should be 1
* Note on the PG or VG percentages on flavors: Some flavors are PG based, some are VG based, some are Ethyl Alcohol based. Working with Ethyl Alcohol based flavorings will reduce your PG/VG ratio. You can substitute one of the Flavor entries with your percentage listed in the “Water/Vodka/PGA” row, so it will not count this towards your ratio.
Now those are your base ingredients. Down below, in the Ingredient section, this is where the final calculations are made. Since you have decided to make a 60/40 blend for your final mixture, change PG to 60%, and VG to 40%. By changing these two fields, it will check your ingredients in the above list and determine which of them are PG or VG base, and at what percentage, and determine what base ingredients are needed to reach 60/40 with correct calculations.
Now that you set your final mixture PG/VG ratio, click on Calculate. You will now be presented with the exact measurements for each of the ingredients that you selected above.
Now you can take your pipettes and measure up the ingredients from their respective bottles and squeeze them into your empty 6ml bottle. Once you have all of the ingredients in the bottle, shake it up and let it rest for a minute or two and test it out.
Does it taste how you like? If it does, GREAT! If you think that the Strawberry is being overpowered by the Banana, then perhaps you need to bump the percentage up to 2%. This is where our own personal taste comes into play.
