How to project revenue with a growth rate
A revenue projection starts from what you earn now and applies a growth rate period after period. The formula for month n is: revenuen = revenue0 × (1 + g)n−1, where g is the net monthly growth rate (growth minus churn). Yearly revenue is the sum of the twelve months, not twelve times the last month — a common mistake in pitch decks that inflates year one.
Use your real trailing growth for the first months and a declining rate afterwards: few businesses sustain the same percentage for five years, because the base keeps getting larger. The calculator lets you test that by running two projections — one at your current rate, one at half of it — and comparing the totals.
Where the growth rate comes from
The rate is the output of your business model, not an input you choose. It follows from your channels (how many customers you can reach at what cost), your revenue streams (what each customer pays and how often), and your customer relationships (how many stay). If you have not mapped those yet, build your Business Model Canvas first, or start from the pitch-deck template.
Worked example
A SaaS earning 10,000 a month, adding 8% of revenue in new business and losing 3% to churn, nets 5% monthly growth. Month 12 is about 17,100; year one totals roughly 159,000; year two totals about 285,000 — an 80% year-on-year increase from a 5% monthly rate. Run the numbers with the break-even calculator to see when that revenue covers fixed costs, and the revenue growth calculator to work backwards from a target.
Frequently asked questions
How do you project revenue from a growth rate?
Multiply each month by (1 + growth rate) to get the next month. Starting at 10,000 with 5% monthly growth: month 2 is 10,500, month 3 is 11,025, and month 12 is about 17,100. The calculator compounds this for you and sums the months into yearly totals.
What is the difference between monthly and annual growth?
5% a month compounds to about 80% a year, not 60%: (1.05)^12 − 1 = 0.796. The calculator shows the annualised rate so monthly assumptions can be compared with yearly targets.
Should I include churn?
For subscription businesses, yes. Enter monthly churn as a percentage of revenue lost; the projection uses net growth (growth minus churn). A business adding 8% and losing 3% a month nets 5%.
How far ahead should I project?
Investors usually want 3 years (36 months) at yearly granularity; an operating budget needs 12 months at monthly granularity. Beyond 5 years a single growth rate stops being credible.
