Calculating Pre-Money Valuation for Startup
Since you have no sales, I'd likely question how well could you determine the value of the company's assets in a reasonable fashion. You may be better to estimate sales and discount that back to a current valuation. For example, insurance companies could determine that if you wanted to be paid $x/month for the rest of your life, the present day value of that is $y. There are similar mechanisms for businesses but this does get tricky as the estimates have to be somewhat conservative and you have to be prepared for some other scenarios. For example, if you got the $200,000 then would you really never have to ask for more external equity financing in the future or is it quite likely that you'd want another infusion down the road? While you can mark it at $1,000,000 there will be questions about why that value that you'd have to answer and saying, "Cause I like big round numbers," may not go over well. My suggestion is to consider what kind of sales will the company have over the next 5 years that you could work back to determine a current price. If you believe the company can have $5,000,000 in sales over the 5 years then it may make sense to place the current valuation of $1,000,000 on it. I wouldn't look too much into the money and time you've invested as that isn't likely to go over well with investors that just because you've put in what is worth $x, the business may or may not be worth that. The challenge is that without sales, it is quite difficult to get an idea of what is the company worth. If it makes billions, then it is worth a lot more than a company that never turns a profit. Another way to consider this is the question of what kind of economic output do you think you could do working here for the next 5 years? Could you do thousands of dollars of work, millions of dollars or just a few bucks? Consider how you want this to be seen where if you want some help look up episodes of TV shows like "Dragon's Den" or "Shark Tank" as these give valuations often as part of the pitch which is what you are doing.
