Whether you are running a small business, pitching investors, or planning your next fiscal year, the question always comes back to the same one: how much profit will I actually make over the next few years? A profit projection turns that vague guess into a number you can plan around. This profit projection calculator takes your Year 1 profit and two year-by-year growth rates, then chains them forward to show Year 2, Year 3, cumulative three-year profit, and the average annual profit you can expect.
The math is deliberately simple and transparent: each year's profit is the prior year's profit multiplied by one plus that year's growth rate. No hidden fees, no discount rates, no inflation adjustments baked in by default. You can stress-test a slowdown by entering a negative growth rate, or model a fast-growth startup by pushing the percentages higher.
How to Use
- Enter your Year 1 Profit — the net profit (revenue minus expenses) you expect in the current or first forecast year. If you are a brand-new business, use your best estimate or a comparable benchmark.
- Set Year 2 Growth as a percentage. A mature, stable business might grow 3–8%; a scaling startup could model 20–50%. Enter a negative number (for example, -10) to model a decline.
- Set Year 3 Growth the same way. Growth rates often slow as a business matures, so it is reasonable to put a smaller number here than in Year 2.
- Read the result card: you will see Year 2 Profit, Year 3 Profit, the Cumulative 3-Year Profit, the Average Annual Profit, and the total percentage growth from Year 1 to Year 3.
- Experiment. Slide Year 2 Growth up and down to see how sensitive your three-year total is to a single percentage point. Run a "downside" case with negative growth and an "upside" case with optimistic growth so you have a planning range rather than a single point estimate.
The engine rejects a negative Year 1 profit — a loss cannot be "grown" forward as if it were a positive base. If your business is currently losing money, enter your expected Year 1 profit after you reach break-even, or model the loss separately on paper.
The Chained Growth Formula
This calculator uses the standard compound growth formula applied one year at a time:
Year 2 Profit = Year 1 Profit × (1 + Year 2 Growth ÷ 100)
Year 3 Profit = Year 2 Profit × (1 + Year 3 Growth ÷ 100)
Cumulative Profit = Year 1 Profit + Year 2 Profit + Year 3 Profit
Worked example on the defaults: Year 1 profit is $50,000, Year 2 growth is 20%, and Year 3 growth is 15%. Year 2 becomes $50,000 × 1.20 = $60,000. Year 3 becomes $60,000 × 1.15 = $69,000. The cumulative three-year profit is $50,000 + $60,000 + $69,000 = $179,000, and the average annual profit is about $59,667. The total growth from Year 1 to Year 3 is 38%, even though the average of the two growth rates is only 17.5% — because each year's growth compounds on top of the prior year's larger base.
This is the same chained-growth model used in standard business plan financials (see Investopedia's overview of profit projections). It is not a discounted cash flow, so the dollars are not adjusted for the time value of money; if you need present-value figures, pair this calculator with a discount-rate tool.
Why Growth Rates Matter More Than They Look
A single percentage point of growth does not move Year 2 by much, but it compounds. On a $50,000 base, 20% versus 21% growth changes Year 2 by only $500. But that $500 also grows in Year 3, and it stacks on top of every other year. Over a three-year horizon, a 5-point difference in growth assumptions can shift cumulative profit by several thousand dollars — which is exactly why investors and lenders ask for downside, base, and upside cases rather than one optimistic number.
Entering a negative growth rate is also useful. If Year 2 growth is -10%, Year 2 profit drops to $45,000, and Year 3 starts from that smaller base. A one-year dip costs you both that year's profit and the compounded growth you would have earned on it in later years.
Examples
Example 1 — The default base case. Year 1 profit of $50,000, Year 2 growth of 20%, Year 3 growth of 15%. The forecast lands on $60,000 in Year 2 and $69,000 in Year 3, for a cumulative three-year profit of $179,000 and an average of about $59,667 per year. This is the classic small-business scaling story: strong growth in year two, then a slight moderation in year three as the market matures.
Example 2 — A mature, slow-growth firm. Year 1 profit is $2,000,000, Year 2 growth is 10%, and Year 3 growth is 10%. Year 2 becomes $2,200,000 and Year 3 becomes $2,420,000. The cumulative three-year profit is $6,620,000, averaging about $2,206,667 per year. Even a steady 10% annual growth turns a $2M business into a $2.42M business in just two years.
Example 3 — A downside / recession case. Year 1 profit is $80,000, Year 2 growth is -15% (a sales slump), and Year 3 growth recovers to 5%. Year 2 drops to $68,000, and Year 3 only recovers to $71,400 — still below the Year 1 starting point. The cumulative three-year profit is about $219,400, roughly what a flat no-growth forecast would have produced. Running this case shows how a single bad year costs two years of growth.
FAQ
What is a profit projection?
A profit projection is an estimate of how much net profit a business will generate in future years, built from a known starting profit and assumed growth rates. This calculator models three years: it takes your Year 1 profit and applies a Year 2 growth rate and a Year 3 growth rate to chain forward.
How is Year 3 profit calculated?
Year 3 profit is Year 2 profit multiplied by one plus the Year 3 growth rate. It is not Year 1 profit times the average of the two growth rates — growth compounds on the prior year, so each year starts from the larger base the previous year created.
Should growth rates slow down in later years?
Usually yes. Most businesses grow faster when small and slow as they scale, because the market gets more competitive and the base gets larger. Entering a smaller Year 3 growth than Year 2 growth is the more realistic assumption for a mature business; a startup pitch deck may assume the opposite for a year or two.
Can I enter a negative growth rate?
Yes. Enter a negative number (for example, -10) to model a profit decline. The calculator chains it the same way: Year 2 profit drops by 10%, and Year 3 starts from that smaller base. You cannot enter a negative Year 1 profit, however — a loss base cannot be "grown" forward.
What is the difference between profit projection and revenue projection?
Revenue projection forecasts only the top line (sales). Profit projection forecasts what is left after all expenses are paid. This calculator uses profit directly, so you do not need to subtract costs again. If you only have revenue figures, subtract your expected costs first to get a profit estimate, then enter that here.
Is this the same as a discounted cash flow or NPV?
No. This calculator shows nominal, undiscounted profit — the actual dollars you expect to earn in each year, adjusted only by your growth assumptions. It does not discount future dollars back to today's value. For investor-grade valuation, pair this output with a discount-rate (NPV) calculator.
How accurate are these projections?
They are only as good as the growth rates you enter. A projection is a planning tool, not a guarantee. Market conditions, competition, costs, and surprises all change real profit. Run at least three cases — conservative, base, and optimistic — and treat the output as a range rather than a single promised number.
