How to determine market growth rate for idea’s which are is not available in the real world yet

For example, I have an app idea which allows users to receive digital receipts straight to there mobile device, eliminating the need for paper based receipts.

I have calculated market size for my app which goes like so:

Market Size (Q) = n x q x p
            (Q) = 23 million x 1 x 1.70
            (Q) = £40 million

Now, I am trying to determine market growth. I have seen many approaches which calculate market growth like this (example):

market was £6.3 million in 2001 & is £34 million in 2006 

34,000,000 - 6,300,000 = 27,700,000 

(27,700,000/6,300,000) x 100 = 439.7% market growth

But the thing is, I do not know what the market size will be in the future. I simply have the current market size and from that I need to determine market growth.

Also, I understand my idea is not unique, but the gap I am exploiting is. I was thinking maybe I have to calculate the market size for my competitors and see the growth they have had between two different years. But that would involve me accessing data such as the indirect costs consumers pay etc. Data which will be hard to obtain.

How do I calculate market growth rate for my scenario?

I’ve searched but cannot find a similar question to this raised days (or a couple of weeks ago). I answered and suggested the product idea you have is not new (though that does not mean you should give up - the market offers us multiple choices when it comes to cars, phones, hotels, airlines etc and no reason why your product could not be considered equally or better than the competition).

However - your question has indeterminable answer - Too many variables exist. It sounds like you are trying to count your chickens before they’ve hatched… it’s a waste of energy and time… best you figure out who might buy it, and how you will market it.

Governments are trying to encourage demand worldwide, hungry to increase interest rates again, when they’ve used every tool in their tool box and even taken the heavy guns out, and they too cannot predict where markets and demand will grow this year, or even if they grow at all this decade. Japan for example has been in a recession for most of the past 20years despite even giving away free money to John and Jane Public at one point.

As a result, your maths formula is speculative - whatever figure you get at the end, you cannot cross reference and prove if it was right or wrong. Comparison with history is not going to direct the present or the future. Think where Nokia was in 2001 and where it is today? Then compare Apple to Android to Windows Phone and Blackberry. Modern devices that perform similar functions yet the first two pretty much own the market.

Your formula cannot calculate demand, nor can it calculate the risks of another better product comming along and taking the traction away from yours.

Your figures also make assumption that many are willing to pay to download the app without competition or any consideration for brand recognition/trust.

Honestly… I would suggest you concentrate on the real world, research your best markets, and promote it there and hope.

Best of luck

I would try to base your growth rate on a similar product or on an industry standard. For instance, what is the average growth rate for new apps? you could use that. But it’s difficult and most of these things are based on a lot of assumptions.

It's understood that, when one creates or reviews projections in a business plan or deck, these numbers were "pulled out of someone's *ss." [I'm being euphemistic, but see @fiprojects excellent breakdown of this issue.]

Put simply, these projections are a kind of fiction, but do provide data on the individual making the projections in terms of vision, and if rationale for the projections is reasonable, some idea of the potential potential.

For my own business plans, I do high/medium/low and even ultra-low (i.e. worst case) projections, but for the actual plan I only include the mid-range.

(Most people seem use high or ultra-high projections, since in very, very, very, very, very, very rare cases they sometime manifest, and everyone wants to invest in "the next Uber".) The tech industry is awash with con-artists, with major emphasis is placed on pump-and-dump enrichment techniques (i.e most people seem to be less interested in creating high-quality, useful products so much as creating "buzz" and finding the "greater fool" to make them rich via acquisition.) This technique won't work unless you have some "heat on you", as they say in Hollywood. (But the best investors are all pessimists -- most startups fail -- which is why I like my budgets to function in worst-case scenarios if I believe in the project;)

Statistics are a powerful tool, but easily and widely abused.

With the caveat that they are still guesses.


PS: Investors will always be most interested in growth markets, so that's a good start, but your own projections of growth won't carry as much weight as a research firm. The problem there is it can be prohibitively expensive for an individual to get access to that kind of data.
