does anyone know of a simple calculator to determine the cost of making DIY juices? I found one that was built into a recipe calculator excel but it was terribly complicated and according to it (if I entered everything correctly) at the prices I paid for my supplies mixing a 6ml bottle costs me about $1.10. Does this sound about right? Normally I wouldn't care if it was getting me off analogs (which it is) but I kinda need to know so I can work out a budget and I suppose it's also for a bit of self reinforcement so I can show myself how much (if any) money I am saving each month by vaping and in turn mention that to anyone who asks me about vaping and how much it costs.
