How to interpret the result

The projection shows where turnover could land if the growth rate you enter holds steady every year, compounding on the year before rather than on the original starting figure. That compounding is the whole point of the tool — a growth rate that looks modest in year one has a noticeably larger effect by the final year of the projection, because each year is growing from an already-larger base. Treat the output as a direction of travel rather than a forecast: it tells you what steady, sustained growth would compound into, not what will actually happen once seasonality, one-off contracts, or a slower quarter enter the picture.

It is most useful compared against your own scenarios rather than read in isolation. Running the same starting revenue through a cautious growth assumption and then a stretch assumption gives you a range to plan around, which is usually more realistic than anchoring on a single number. It also pairs naturally with the site's profit target revenue calculator, which comes at the same question of headroom from the margin side rather than the growth-rate side.

Limitations and good practice

A constant compound rate is a simplification. Real revenue growth tends to arrive in steps — a new client, a price rise, a seasonal peak — rather than as a smooth annual percentage, so the projection is best treated as an illustrative trend line rather than a month-by-month budget. It also assumes nothing structural changes: no shift in pricing, customer mix, or market conditions over the period you're projecting. The further out you project, the more those assumptions are doing the work, so shorter projections tend to be more trustworthy than long ones.

Good practice is to revisit the inputs regularly rather than treating one projection as fixed. As actual figures come in, feed the real growth rate back into the calculator to see whether the trajectory still looks the same, and keep the result anchored to management accounts rather than aspiration. For the practical, non-numerical side of chasing growth — what it means for cash tied up in the business as it scales — the site's wider Learn hub covers the operational groundwork alongside the arithmetic here.
