What it means
A projection normally covers three linked statements: a projected income statement, a projected cash flow and a projected balance sheet. Even a simple version should link them, because a revenue projection that is not converted into expected cash receipts can be badly misleading.
Projections matter because money is committed on the strength of them. Lenders, investors, landlords and boards all approve spending based on what the numbers say will happen, and they will hold management to the assumptions behind those numbers.
The practical method is to project drivers rather than totals. Instead of stating that revenue will be $3,000,000, a good projection states customer numbers, average order value and purchase frequency, so each assumption can be argued about and tested separately.
Ranges beat single figures. Experienced readers expect at least a base case and a downside case, along with a short sensitivity note showing what happens to profit and cash if the biggest assumption, usually sales volume, comes in 20% below plan.
There is a useful distinction between a forecast and a projection. A forecast usually reflects the most likely outcome given current conditions, while a projection often explores a specific scenario such as winning a large contract or opening a new site.
The common failure is not being wrong, since every projection is wrong to some degree. The failure is being wrong without knowing which assumption broke, which is why every projection should be reviewed against actual results so the next one is better calibrated.
In practice
Real-world examples.
Example
A café chain projects the first three years of a new site using footfall counts from a similar location, an average spend of $9.50 and a 12 week ramp-up to full trade. The projection shows breakeven in month eight, and the landlord accepts a rent-free period on that basis.
Example
A medical device start-up prepares projections for an investor pitch showing three scenarios tied to regulatory approval timing. The investor spends most of the meeting on the slowest scenario, because that case determines how much funding is genuinely needed.
Example
A logistics company projects fuel costs separately from other overheads because fuel is roughly a quarter of its cost base. When diesel prices move sharply, the finance team reruns only that assumption and reissues an updated projection within a day.

Formula
Calculation
A basic revenue projection compounds a growth rate:
Projected revenue in year n = current revenue x (1 + growth rate) raised to the power n
A speciality food wholesaler currently has revenue of $1,200,000 and projects 15% annual growth for three years, holding gross margin at 40%.
Year 1 revenue = $1,200,000 x 1.15 = $1,380,000.
Year 2 revenue = $1,380,000 x 1.15 = $1,587,000.
Year 3 revenue = $1,587,000 x 1.15 = $1,825,050.
Projected year 3 gross profit = $1,825,050 x 0.40 = $730,020.
If fixed overheads are projected at $560,000 in year 3, projected operating profit is $730,020 - $560,000 = $170,020.
A downside case at 5% growth gives year 3 revenue of $1,200,000 x 1.05 x 1.05 x 1.05 = $1,389,150 and gross profit of $555,660, which is below the $560,000 of overheads. That single comparison tells the owner the plan only works if growth stays comfortably above 5%.Case study
Seen in the real world.
This is an illustrative, fictional example. Northaven Cycles, an invented online bike retailer, prepared a projection for its investors showing revenue rising from $4,000,000 to $10,000,000 over three years. The projection was built by typing a growth percentage into a spreadsheet and letting it compound.
Two years in, revenue had reached only $5,600,000. Because nothing underneath the headline was documented, nobody could say whether the shortfall came from fewer visitors, a lower conversion rate or a smaller average basket. The board lost confidence in every number the company produced.
In this fictional turnaround, the new finance lead rebuilt the projection from four drivers: site visitors, conversion rate, average order value and repeat purchase rate. Actual results were compared against each driver monthly, and within two quarters the company could explain variances precisely and, more importantly, act on the right one.
Watch out
Common mistakes.
- Projecting a smooth growth percentage with no underlying drivers, which produces a number nobody can defend or diagnose when reality differs.
- Projecting revenue and profit but not cash, so the working capital needed to fund growth in stock and unpaid invoices is left out entirely.
- Presenting only an optimistic case, which damages credibility with lenders and investors who will simply build their own downside version anyway.
Questions
People also ask.
How far out should a financial projection go?
Three years is the usual span for external audiences, with the first year in monthly detail and later years in quarters or annual totals, since precision beyond that is largely false comfort.
What is the difference between a projection and a budget?
A projection is an expectation of what will happen under stated assumptions, whereas a budget is an approved commitment that individuals are held accountable to.
How accurate should a projection be?
Being within roughly 10% on revenue in year one is a reasonable ambition for an established business, but the more useful test is whether the reasons for any variance can be explained and corrected.
