Why a ballpark figure matters to a first-time founder
A ballpark figure helps you decide whether an idea deserves detailed work. It can expose that a project is clearly affordable or impossible without pretending to precision. State the range, assumptions and uncertainty so nobody later treats an early estimate as a quote or commitment.
Examples of ballpark figures
A Nigerian founder asks what a first product launch might cost. Based on similar work, the team gives a ballpark of ₦12 million to ₦18 million, assuming one platform and no regulated payments. That range is enough to compare the idea with available funding.
Common misunderstanding
It is not a formal quote, approved budget or reliable forecast. A useful ballpark still needs a clear basis and order of magnitude; it is not a number invented in the meeting. As scope becomes known, replace it with a documented estimate and then firm supplier prices.
When to use it
Use one during discovery, early fundraising or a quick option screen when exact inputs do not yet exist. Give a range and name the biggest unknowns. Do not use a ballpark to sign a fixed-price contract, promise a delivery date or make a decision near your cash limit.
