About the Financial Projection Calculator

The Financial Projection Calculator builds a simplified multi-year business plan from just a few growth assumptions. Enter your first year's revenue and expenses along with expected annual growth rates for each, and it projects Revenue, Expenses, Pretax Profit, Tax, and Net Profit for every year from year 1 through the number of years you choose (3, 4, or 5), plus the cumulative profit across the whole period and the underlying revenue CAGR.

How It Works

Each year's Revenue and Expenses compound forward from the year 1 figures using your entered growth rates: Revenue in year i equals Year 1 Revenue times (1 + growth rate)^(i-1), and the same pattern applies to Expenses. Pretax Profit is Revenue minus Expenses for that year. Tax is applied only to positive pretax profit at your entered tax rate — loss years owe no tax in this simplified model. Net Profit is Pretax Profit minus Tax, and Cumulative Net Profit is the running total of Net Profit across every projected year. Revenue CAGR is calculated from the first and last projected year's revenue, which for a constant growth-rate model comes out equal to the growth rate you entered — a useful sanity check on the projection.

Why It Matters

A multi-year projection turns a single "we'll grow fast" assumption into concrete numbers you can stress-test, share with investors or lenders, and use to plan hiring, fundraising, and spending. Seeing net margin expand or contract year over year quickly shows whether your growth plan is actually becoming more profitable over time or just getting bigger while staying thin-margined.

Tips for Accurate Results

  • Base your Year 1 figures on actual results or a well-researched budget, not a hopeful guess — every later year compounds from this starting point.
  • Keep your revenue and expense growth rates realistic and grounded in your specific market and unit economics rather than industry averages.
  • Remember this is a simplification: real growth is lumpier than a constant compounding rate, so treat the output as directional planning, not a precise forecast.
  • Pair this projection with a full financial model — including cash flow timing, working capital, and CapEx — before making major financing decisions.

This is an estimate for planning purposes — consult a licensed accountant or financial advisor before using these figures for tax filing or formal fundraising documents.

Formula

How the Financial Projection is Calculated

Revenue and expenses each compound forward at their own growth rate every year.

Financial Projection Formula
Revenue(year i) = Year 1 Revenue × (1 + Revenue Growth)^(i−1)
Expenses(year i) = Year 1 Expenses × (1 + Expense Growth)^(i−1)
Net Profit(year i) = (Revenue − Expenses) − Tax on positive Pretax Profit
📈

Compounding Growth

Even modest annual growth rates compound significantly over 3-5 years — small differences in assumptions produce large differences in outcomes.

🧮

Watch Net Margin

Net Margin = Net Profit ÷ Revenue. Rising net margin over the projection means the business scales efficiently; falling margin is a warning sign.

🎯

CAGR as a Sanity Check

Revenue CAGR should roughly match your entered growth rate. If it doesn't, double-check your year count and growth assumptions.

FAQ

Frequently Asked Questions

Common questions about financial projections

Why project multiple years for a business plan?
Multi-year projections show whether a business trajectory is sustainable, help set fundraising and hiring plans, and are typically required by lenders and investors evaluating a business plan. A single year rarely shows the compounding effect of growth on profitability.
Is a straight compounding growth rate realistic?
No — it's a simplification. Real business growth is lumpier: it comes in bursts tied to product launches, seasonality, market shifts, and one-off deals rather than a smooth constant percentage every year. Use a constant-growth projection for directional planning, not as a precise forecast.
How does expense growth typically compare to revenue growth for healthy scaling?
In a healthy scaling business, expenses generally grow slower than revenue after the early years, since fixed costs and infrastructure investments are spread across a larger revenue base — this is what drives expanding net margins over time. If expenses consistently grow faster than revenue, profitability erodes even as the business gets bigger.
What's included in a full financial projection beyond this simplified model?
A complete financial model also includes cash flow timing (when revenue is actually collected vs. billed), working capital needs, capital expenditures (CapEx), depreciation, debt service, and detailed headcount and department-level budgets. This calculator focuses on the headline revenue, expense, and profit trend for quick planning.
What happens if expenses exceed revenue in a projected year?
The calculator shows a negative Pretax Profit for that year, and no tax is applied since the model only taxes positive pretax profit. That year's negative Net Profit still flows into the Cumulative Net Profit total, dragging it down.
How is Net Margin calculated, and why does it matter?
Net Margin equals Net Profit divided by Revenue for that year, shown in the year-by-year table. A rising net margin over the projection means the business is becoming more profitable as it scales; a falling margin signals that costs are growing faster than revenue can support.
Why does my Revenue CAGR come out equal to the growth rate I entered?
Because this calculator applies one constant Revenue Growth rate to every year, the compound annual growth rate calculated from the first and last year's revenue mathematically works out to that same rate. If they don't match, double-check the number of years and growth rate you entered.
Should I enter my statutory tax rate or my effective tax rate?
Either can work depending on your goal, but for a more realistic projection use your expected effective tax rate — the actual percentage of pretax profit you expect to pay after deductions and credits — rather than the top statutory rate, which usually overstates the tax burden.
Can I project just 1 or 2 years instead of 3-5?
The dropdown only offers 3, 4, or 5 years, since multi-year trend visibility is the point of this tool. For a single year's numbers, simply read the Year 1 row of the breakdown table and ignore the later years.
Does this projection account for inflation?
Not explicitly. Your entered growth rates should already reflect nominal (inflation-included) growth if you want nominal dollar outputs, or you can enter real growth rates if you want the results expressed in today's purchasing power — just be consistent between revenue and expense growth assumptions.
How is Cumulative Net Profit different from Final Year Net Profit?
Final Year Net Profit is the after-tax profit in just the last projected year. Cumulative Net Profit is the sum of every year's Net Profit added together across the whole projection period, giving you the total profit the business is expected to generate over the full 3-5 years, not just at the end.
