Build next year's number from the bottom up
It's planning season, which means somewhere a number is being handed down. Last year plus thirty percent, because the board wants a story and thirty is a round, confident figure. The slide looks clean. Then it reaches the people who have to carry it, everyone quietly runs the math that says it can't be done, and they start managing their own expectations instead of the plan.
A number built from the top down is a wish with a deadline. A number built from the bottom up is a commitment, because the people who have to hit it helped build it and can see the path to it. The difference shows up in February, when the first soft month either triggers panic or triggers an adjustment you already knew you might need.
Start with capacity, not ambition
The honest way to build next year's number starts with what your team can actually produce, not with what you wish they would. Take a ramped, fully productive rep and ask what they reliably close in a year — not their best quarter annualized, their real repeatable output. That is your unit of capacity, and everything else in the plan is a multiplier on it.
Now count how many of those units you will truly have, month by month. A rep hired in March isn't a full unit this year; they're a fraction, discounted by ramp time. A rep who leaves in June takes their pipeline with them. Attrition is not a footnote — plan for it on purpose, because pretending everyone stays is the most common way a plan quietly inflates itself past reality.
A target your team can't trace back to capacity isn't a plan. It's a hope with your name on it.
Pressure-test the plan against pipeline reality
Capacity tells you what the team can sell. Pipeline math tells you whether the funnel can feed them enough to do it. Walk the number backward: to close the plan, how much qualified pipeline do you need, given your real win rate and sales cycle? Then ask the uncomfortable question — where does that pipeline come from, and is the demand engine actually resourced to create it?
This is where most plans quietly break. The quota gets built from capacity in one room, the demand plan gets built in another, and no one checks that they add up. If your number needs forty percent more pipeline than you generated this year and nothing in the demand plan changes, you don't have a plan — you have a gap nobody has named yet.
- Fully-ramped productivity per rep — the real, repeatable figure, not the best case.
- Headcount by month, with ramp curves and expected attrition built in.
- Win rate and sales cycle, by segment, drawn from your actual history.
- Pipeline coverage required to hit the number — and where that pipeline originates.
- Expansion and renewal assumptions, held to the same scrutiny as new business.
Close the gap on purpose
When the bottoms-up number lands short of the target — and it usually will — resist the urge to simply type the bigger number anyway. That gap is the most useful output of the whole exercise. It tells you exactly how much growth has to come from something other than your current team doing more of the same.
Name the levers out loud and fund them. Hire earlier, so reps are productive by Q2 instead of Q4. Lift win rate with sharper qualification. Open an expansion motion into the base you already won. Add a channel. Each lever carries a cost and a ramp of its own, and each belongs in the plan as a line item, not a hope. A gap you've funded is a strategy. A gap you've papered over is next year's miss.
Write the assumptions down
The last step is the one almost everyone skips: write down the assumptions the number rests on. Productivity, ramp, attrition, win rate, pipeline coverage, the contribution of each growth lever. Put them somewhere the whole leadership team can see and agree to.
Do that and the plan becomes diagnostic instead of decorative. When March comes in light, you don't argue about whether the team is working hard enough — you look at which assumption broke. Pipeline short? Ramp slower than planned? Win rate slipped? You adjust that specific lever, early, while there's still year left to recover. A number built from the bottom up doesn't just tell you what to hit. It tells you what to do when you're not hitting it — which is the only part of planning that actually protects the year.
