Hockeystick Revenue Model Calculator
A hockey stick revenue model holds revenue flat while a startup finds its footing, then compounds it at one monthly growth rate from a chosen start month. This calculator projects that curve for 12 to 36 months and reports revenue at month 12, revenue at the final month, total cumulative revenue, the growth multiple, an annual run rate, and a written assessment of the trajectory for your business model. It uses one growth rate and a genuinely flat early phase, and the article below says so plainly, because plenty of pages describe a two-rate model their tool does not actually run.
Quick Answer
At the pre-filled settings ($10,000 initial monthly revenue, 20% monthly growth starting month 6, SaaS, 24 months), revenue stays at $10,000 through month 6, reaches $29,859.84 at month 12 and $266,233.333 at month 24, for $1,597,399.997 in total cumulative revenue and a 26.6x growth multiple the tool rates an Exceptional Growth Model. The output fields show the tool’s own formatting, up to three decimal places, which is why the final and total figures carry the extra digits.
Key takeaways
- The early phase is exactly flat. There is no slow-growth rate in this tool, only 0% before the start month and your chosen rate from that month on.
- The start month itself still shows the initial revenue. Compounding has an exponent of zero that month, so the first increase appears one month later.
- The business model dropdown changes the written analysis and its benchmark range only. It never changes a revenue number.
- A constant 20% monthly rate compounds to 26.6x in 19 growth-phase months. Treat the far end of the curve as a stress case, not a promise.

How to use the hockey stick revenue model calculator
Enter a starting revenue, one monthly growth rate, the month growth begins, a projection length and a business model, then click Calculate. Results stay hidden until you do, and nothing recalculates on its own while you type.
- Initial monthly revenue: your month 1 revenue. The model holds this exact figure for every month before the start month, so a business still pre-revenue should model from its first expected revenue month, not from zero (zero is rejected).
- Monthly growth rate: the one rate that compounds from the start month onward. This is the same compounding the exponential growth calculator isolates on its own, applied here to revenue after a flat phase.
- Growth phase start month: the inflection month. Note the tool’s exact convention: revenue in the start month is still the initial revenue, because the exponent counts full months elapsed since the start month. Start month 6 means months 1 to 6 are flat and month 7 is the first higher month.
- Projection period: 12, 18, 24 or 36 months. At high rates the 36-month runs produce multiples in the thousands, which the analysis flags as hyper-growth rather than celebrating.
- Business model: pick the closest match for the written analysis. It swaps in that model’s benchmark range (SaaS 10-20% a month, marketplaces 15-30%, mobile apps 20-50%, and so on) and leaves every number untouched.
- Read all four outputs together: month 12, final month, cumulative total and the multiple describe different things. A big final month with a modest cumulative total means most of the money arrives very late, which matters for cash planning.
The formula: flat first, then one compounding rate
Each month’s revenue is either the initial revenue (before the start month) or the initial revenue compounded for the months elapsed since the start month. There is no third case and no second growth rate.
From the start month: Revenue(month) = Initial revenue × (1 + growth rate)(month − start month)
Total cumulative revenue = the sum of all monthly revenues in the projection
Growth multiple = Final month revenue ÷ Initial revenue
Annual run rate = Final month revenue × 12
Two details in that formula explain most surprises. First, the exponent at the start month is zero, so the curve leaves the flat phase one month after the month you name. Second, the analysis panel’s “average monthly growth” figure is not your input rate: the tool derives it as (final ÷ initial)1/(period − 1) − 1, spreading the whole multiple across every month including the flat ones. In the worked example your 20% input becomes a 15.3% average, which is the honest number to quote if someone asks what the whole two years averaged. If you need the equivalent annual figure for a pitch, the compound annual growth calculator converts a start-to-finish multiple into a yearly rate, and the growth rate calculator measures the rate you actually achieved between two recorded figures, which is the right check on whether a hockey stick assumption survived contact with real trading.
Months 1 to start month: revenue equals the initial figure every month.
The start month is the hinge. Its revenue is still flat; growth is counted from here.
Each later month multiplies the initial revenue by (1 + rate) once more.
Month 12, final month, cumulative total, multiple and run rate, plus the assessment.
Worked example: $10,000 a month, 20% growth from month 6, 24 months
Every number here is the calculator’s own output for the pre-filled inputs, in the tool’s own display format. Run it yourself before quoting any of it.
- Months 1 to 6 are flat at $10,000. The pre-growth phase (the 5 months before the start month, as the analysis counts it) contributes $50,000.
- Month 12 revenue = $10,000 × 1.206 = $29,859.84.
- Month 24 revenue = $10,000 × 1.2018 = $266,233.333, a 26.6x multiple, rated Exceptional Growth Model (the 20x to 50x band).
- Total cumulative revenue = $1,597,399.997, of which the growth phase contributes $1,547,399.997, or 97%.
- Annual run rate at month 24 = $266,233.333 × 12 = $3,194,799.994.
- The analysis panel’s funding note for this tier reads: high-growth trajectory may require $2,555,839.995 to $5,111,679.99 in annual funding for scaling. That estimate is the tool’s own rule of thumb (final-month revenue times 0.8, scaled by tier), not a quote from any lender.
Earlier versions of this page printed a different example ($35,831 at month 12, $191,687 at month 24, about $1.9M total). Those figures do not come out of this tool for these inputs, in either direction, so they have been replaced with the verified run above. The scenario table below is four more verified runs, chosen to show how sharply the start month and the rate move the outcome.
| Scenario (all verified tool runs) | Month 12 | Final month | Cumulative total | Multiple | Assessment |
|---|---|---|---|---|---|
| $10,000 start, 20%/mo from month 6, 24 months, SaaS | $29,859.84 | $266,233.333 | $1,597,399.997 | 26.6x | Exceptional Growth Model |
| $5,000 start, 10%/mo from month 3, 18 months, Marketplace | $11,789.738 | $20,886.241 | $189,748.649 | 4.2x | Limited Growth Acceleration |
| $20,000 start, 15%/mo from month 12, 36 months, Other | $20,000 | $572,503.524 | $4,475,860.349 | 28.6x | Exceptional Growth Model |
| $10,000 start, 0%/mo from month 6, 24 months, SaaS | $10,000 | $10,000 | $240,000 | 1.0x | Limited Growth Acceleration |
The third row is worth a second look: with a month 12 start, the month 12 field still shows the flat $20,000, because that month’s exponent is zero. Anyone presenting the month 12 figure as “growth achieved in year one” for a late-start model would be misreading their own chart.
Reading the analysis: tiers, benchmarks and the funding note
The written analysis under the outputs grades the multiple into five bands and quotes the benchmark range for the business model you picked. Both tables come straight from the tool’s code, so you can predict the verdict before you run a scenario.
| Growth multiple | Assessment the tool prints | What it is really telling you |
|---|---|---|
| 50x or more | Hyper-Growth Trajectory | The maths has outrun operations. Expect the sustainability warning and the largest funding estimate. |
| 20x to under 50x | Exceptional Growth Model | A classic hockey stick shape on paper. The worked example (26.6x) lands here. |
| 10x to under 20x | Strong Growth Trajectory | High growth that stays nearer the plausible band for a two-year window. |
| 5x to under 10x | Moderate Growth Pattern | Real acceleration, short of venture-scale. Often the most defensible case to present. |
| Under 5x | Limited Growth Acceleration | The curve barely bends. A 0% rate scores 1.0x and this verdict, correctly. |
The benchmark ranges quoted per model are SaaS 10-20% monthly, marketplace 15-30%, e-commerce 10-25%, mobile app 20-50%, fintech 15-25% and other 10-30%. Treat them as the tool’s built-in orientation figures, not measured market data: sustained monthly growth at the top of any of these ranges is rare in published startup data, and writers such as Paul Graham have argued that a good startup grows its revenue roughly 5 to 7 percent per week at the early stage, which compounds fast but is measured in weeks of exceptional performance, not years of it. The U.S. Small Business Administration’s guidance on writing a business plan makes the matching point from the lender’s side: projections need stated assumptions a reader can challenge, which is exactly what a one-rate model gives you.
What competing calculators miss
For this exact keyword the field is thin, and the gaps are specific:
- CalculatorsHub hockeystick calculator: the one genuine rival tool, and in one respect the more realistic model: it takes a slow growth rate for the blade and a separate rapid rate for the shaft, where this tool’s blade is flat. Its readout stops at final revenue, total revenue and a compound monthly growth rate. It has no month-12 checkpoint, no cumulative-versus-final split, no run rate and no written assessment of the trajectory.
- SaaS revenue projectors (SaaSProjector and similar): richer mechanics, with customers, churn and ARPU driving MRR month by month. Better for an operating SaaS business, slower for the question this page answers: what does a flat-then-exponential curve look like from four assumptions?
- Forecasting calculators (CalculatorWise and similar): compound a single rate from day one, with sensible warnings about ceilings and confidence ranges, but no flat phase at all, so they cannot draw the hockey stick shape itself.
- Spreadsheet templates and investor guides: plenty of hockey stick commentary, including good warnings that year-3 spikes trigger investor scepticism, but nothing you can run. The advice and the arithmetic live on different pages.
- The gap this page fills: the four headline outputs plus a graded written analysis (tier, benchmark for your model, funding-range note, market-timing and sustainability notes) from one run, with the model’s limits stated on the page: flat blade, one rate, no costs, no churn, no market ceiling.
Where this model breaks, and what to pair it with
A hockey stick projection is an assumption drawn as a curve, and this one carries four limits you should keep in front of anyone you show it to. The rate never decays, so month 36 at 30% produces a 5,756.1x multiple on a $1,000,000 start in the tool’s own arithmetic; real markets cap growth long before that. The model has no churn, no costs and no seasonality, so it says nothing about profit or cash, only revenue. The flat phase is a simplification: most young businesses grow slowly rather than not at all, which is the one place the two-rate rival model is closer to life. And a projection is not evidence; the SBA’s startup cost guidance and the Federal Reserve’s Small Business Credit Survey both underline how wide the gap between planned and actual early revenue usually is.
Used well, the tool does one job: it turns “we will grow fast later” into four checkable numbers and a graded verdict, in about a minute. Pair it with a bottom-up model (customers times price, with churn) before anything goes in a deck, and re-run it with the rate you actually achieved last quarter. If the honest rate gives a Limited verdict, that is the tool working, not failing.
Frequently asked questions
It is a revenue curve that stays flat, or nearly flat, during an early phase and then rises steeply as growth compounds. The name comes from the shape: a short flat blade, then a long rising shaft. This calculator models the early phase as exactly flat and the rising phase as one monthly growth rate compounded from a start month you choose.
No. This tool has one growth rate, and the phase before it is flat at 0 percent, not a slower rate. Some rival calculators take a separate slow rate for the early phase; this one keeps the blade flat so the inflection is stark and the assumption is easy to state. If your business grows slowly rather than not at all, treat the flat phase as a conservative simplification.
Because the formula compounds for the months elapsed since the start month, and in the start month itself zero months have elapsed, so the multiplier is (1 + rate) to the power zero, which is 1. With a start month of 6, months 1 to 6 show the initial revenue and month 7 is the first month that grows.
Only the written analysis. Each model carries its own benchmark range and characteristics in the analysis panel (SaaS 10-20% monthly, marketplace 15-30%, e-commerce 10-25%, mobile app 20-50%, fintech 15-25%, other 10-30%), and the model name appears in the projection summary and the copied result text. The revenue figures, the multiple and the assessment tier are identical whichever model you pick.
When the growth phase start month is 12 or later, month 12 is still in, or just leaving, the flat phase, so its revenue is the initial figure. In a 12-month projection the month 12 and final month fields are also the same month, so the two fields match. Neither case is an error; both follow from the flat-then-compound formula.
As arithmetic, yes: 20 percent compounded monthly for 18 growth months multiplies revenue by about 26.6. As a forecast, it is an aggressive assumption that the tool grades Exceptional and pairs with a sustainability note and a funding estimate, because holding 20 percent monthly growth for a year and a half is rare. Run a lower rate as a second scenario and present both, rather than presenting the steepest curve you can type.
No. It projects revenue only, from revenue assumptions. There are no expense, churn, seasonality, or tax inputs, and the funding figures in the analysis are the tool’s own rules of thumb built from final-month revenue, not a cash flow forecast. Pair the output with a costs model before using it for budgets or fundraising.
The projection period options are 12, 18, 24 and 36 months, and the growth start month must fall inside the period you choose. Shorter is usually more honest: a constant monthly rate compounds without any market ceiling, so the 36-month runs at high rates produce multiples in the thousands that the analysis itself flags as hyper-growth. The tool works in months only; it has no yearly input mode.
