Quick Answer
To model growth scenarios, identify the 5-7 key growth drivers for your business — new customer acquisition, expansion revenue, pricing, market penetration — and create distinct assumption sets for each scenario. Model conservative growth (10-15% below base), base case, and aggressive growth (20-30% above base). For each scenario, ensure costs scale appropriately — growth requires investment in sales, infrastructure, and support — so the P&L impact is realistic.
Growth is rarely linear or predictable. Modelling different growth trajectories helps leadership understand the trade-offs between growth rate and profitability, plan capacity, and make informed investment decisions.
Conservative growth: What happens if you grow slower than planned? Maybe the market is tougher, sales cycles are longer, or churn is higher. This scenario typically models 10-20% below base case growth.
Base case growth: Your most likely trajectory, grounded in current pipeline, historical conversion rates, and realistic market assumptions.
Aggressive growth: What happens if you invest more heavily and market conditions are favourable? This scenario typically models 20-40% above base case, but with correspondingly higher costs.
Hypergrowth: For venture-backed companies, model what happens at 2-3x growth — the strain on operations, cash burn, and team capacity. This informs fundraising discussions.
The most common mistake in growth scenarios is modelling higher revenue without scaling costs. Faster growth requires: - More sales and marketing spend to drive pipeline - More customer success and support capacity - Infrastructure scaling (hosting, tools, office space) - Higher recruitment costs and earlier hiring - Potentially lower unit economics during rapid scaling
Model these cost implications explicitly. A 50% growth scenario with flat costs is fiction, not planning.
Every business has constraints that limit growth rate: - Sales capacity (reps x quota attainment) - Product capacity (can you onboard that many customers?) - Support capacity (can you maintain quality at higher volume?) - Cash (does faster growth burn more cash before it generates returns?)
Model these constraints so leadership understands what bottlenecks need to be solved to achieve each growth rate.

| Metric | Conservative | Base | Aggressive | |--------|-------------|------|------------| | Revenue growth | 15% | 30% | 50% | | Required headcount adds | 10 | 20 | 35 | | Marketing spend | £500K | £800K | £1.2M | | EBITDA margin | 18% | 12% | 3% | | Cash runway | 24 months | 18 months | 10 months |
This shows the trade-off between growth rate and profitability/cash clearly.

Use historical growth rates as a baseline. For the conservative case, assume growth decelerates. For the base case, apply realistic assumptions from pipeline and market data. For aggressive, model what is achievable with incremental investment. Validate against industry benchmarks.
Yes, if your business has meaningful segments. Growth rates often differ significantly between segments — your core market may be slowing while a new segment is accelerating. Segment-level modelling gives a more accurate picture.
Faster growth typically burns more cash before generating returns. Model the cash investment needed (hiring, marketing, infrastructure), the time lag before revenue materialises, and the working capital requirements. Show cash runway under each growth scenario.
Show them the trade-off clearly. Present a growth-profitability frontier showing what margin is achievable at each growth rate. This makes the trade-off explicit and forces a strategic choice rather than an impossible mandate.
Yes. Create separate scenarios in Grove FP with different growth assumptions. The model automatically recalculates costs, cash flow, and KPIs for each scenario. Compare any two scenarios side by side with one click.
