Investors use your financial projections to test your competence, not to see a perfect prediction. Build a bottoms-up, three-year forecast based on key assumptions about your business drivers (hiring, conversion rates, ACV). Connect your "Ask" directly to the hires and activities that will let you hit the milestones shown in your projections.
Key takeaways
- Stop trying to predict the future; use financials to show you understand your business model.
- Build your projections "bottoms-up" from drivers you control, like hiring and sales quotas.
- Limit your deck to three core slides: Historicals, Projections, and Use of Funds.
- Your "Use of Funds" must explicitly link your fundraise to your projected growth.
- For pre-seed, a simple budget and Use of Funds is often enough; post-revenue, a 3-year P&L is standard.
- Always include a slide on your key assumptions; it's more important than the projection itself.
Your Financials Aren't a Prediction—They're a Test
Investors spend disproportionate time on your financial slides, but not for the reason you think. They know your five-year forecast is fiction. The real reason is that financials are the single best test of your competence as an operator.
Your projections reveal how you think. They prove you understand the levers of your business, the cause-and-effect between spending money and making money, and whether your ambition is venture-scale. They are a story about your company's future, written in the language of numbers.
A generic, top-down model ("We'll capture 1% of this $50B market") tells an investor you're either naive or lazy. A thoughtful, bottoms-up model ("We’ll hire 3 AEs who each ramp to a $600k quota in 6 months, driven by a $20k/month marketing spend") demonstrates you have a credible plan.
This guide will teach you to build financials that tell a compelling story and prove you are a founder worth backing.
The Three-Act Story of Your Financials
Keep your in-deck financials high-level and narrative-driven. Your goal is to tell a story in three acts. The 47-tab spreadsheet is for the data room during late-stage diligence, not the first meeting. For nearly all pre-seed and seed decks, you only need three slides.
Act I: The Historicals / Traction Slide
If you have any operating history, however small, lead with it. This slide establishes your baseline reality and proves you can execute. Nothing grounds a forward-looking plan like a backward-looking track record.
If you have revenue: Show a simple bar chart of the last 6-12 months of revenue (ideally Monthly Recurring Revenue, or MRR). Clearly label the compound monthly growth rate (CMGR). For top-quartile B2B SaaS companies at the seed stage, this is often in the 15-20%+ range. Don't hide your numbers; if you're at $10k MRR, show it proudly. · If you're pre-revenue: Show what you do have. This could be user growth (Week-over-Week or Month-over-Month), engagement (DAU/MAU ratios), a waitlist of qualified leads, or pilot program traction. The goal is to show a compelling upward slope on a key metric.
Keep it clean and visual. This slide’s only job is to create credibility for the plan that follows.
Act II: The Projections & Assumptions
This is where you outline your plan for growth. Investors will immediately try to reverse-engineer your numbers, so you must show your work. The best way to do this is with two slides: one detailing your core assumptions, and one showing the resulting financial projections.
Slide 1: The Key Assumptions
This is the most important financial slide in your deck. It lists the 3-5 core drivers of your model. It shows investors exactly how you think your business works.
Revenue Drivers: · Avg. Contract Value (ACV): $15,000 · Sales Rep Quota: $500,000 in new ARR per year, with a 6-month ramp period. · Lead Velocity: Each $10,000 in monthly marketing spend generates 40 qualified demos. · Churn & Expansion: 1.5% monthly logo churn and 2.5% monthly expansion revenue, for 1% net monthly revenue retention.
Hiring Plan: Hire 4 Engineers and 2 AEs in the first 6 months. · Fully-Loaded Employee Cost: $175k/year for engineers, $140k/year for AEs (includes salary, benefits, payroll taxes - typically 1.3-1.4x base salary).
Slide 2: The Financial Projections
After grounding the investor in your assumptions, present a high-level P&L forecast. For a seed-stage company, project three years out. A five-year projection is too speculative. Show Year 1 by quarter and Years 2 & 3 annually. This shows both near-term execution and long-term ambition.
Revenue · Cost of Goods Sold (COGS): Direct costs of your product (hosting, data providers, transaction fees). For software, this should be low. · Gross Profit (Revenue - COGS) · Operating Expenses (OpEx): Grouped into buckets – Sales & Marketing (S&M), Research & Development (R&D), and General & Administrative (G&A). · EBITDA or Net Income
The output should feel like an inevitable consequence of the assumptions you just presented.
Act III: The Ask & Use of Funds
This slide connects your plan (Act II) to the capital you need to achieve it. It explains how much you're raising, how long it will last, and how you'll deploy it to reach the next fundable milestone.
The Ask: Be specific. "We are raising a $2M seed round." · The Runway: State how long this capital will last. For a seed round, the standard is 18-24 months. Anything less invites questions about your planning. · The Use of Funds: A simple chart and text explaining how you'll allocate the capital. This must tie directly back to your assumptions and projections.
70% Team ($1.4M): "Hire 4 senior engineers to build out our enterprise features and 2 account executives to expand our sales coverage." This payroll number should reflect the 18-month loaded cost of these hires. · 20% Go-to-Market ($400k): "Fund the marketing programs needed to generate the pipeline for our new account executives and scale from $25k to $100k MRR." · 10% G&A & Buffer ($200k): "Cover operational costs and provide a 3-month cash buffer for unforeseen challenges or opportunities."
Crucially, you must explicitly state what this capital achieves: "This $2M raise provides 18 months of runway for us to grow from $25k MRR to $100k MRR, setting us up for a successful Series A."
Red Flags: Common Mistakes That Kill Credibility
Investors are pattern-matchers. Here are the common financial mistakes that signal inexperience.
The Unconnected Hockey Stick: Your revenue explodes in Year 2, but your hiring and marketing spend stay flat. An investor knows growth isn't free. Your revenue growth must be a direct result of the investments in team and marketing outlined in your Use of Funds. · Unrealistic Margins: Benchmarks matter. If you project 99% gross margins for your SaaS company, you’ve forgotten about AWS hosting, Stripe fees, and customer support staff. If your DTC gross margins are 25%, you’ll never afford marketing. Know the standards for your industry (e.g., 80%+ for SaaS, 50-60% for best-in-class DTC). · Underestimating Payroll Costs: A junior founder models salaries. A pro models fully-loaded costs (salary, taxes, benefits, perks), which are typically 1.3-1.4x the base salary. Using the wrong number means you will run out of money 30% faster than planned. · The "Kitchen Sink" P&L: Your deck includes a 30-line P&L with entries for "Office Supplies" and "Travel." This buries the narrative and wastes attention. Keep the deck high-level; the detailed model lives in the data room. · Over-engineering Pre-Seed Financials: You're raising a $750k pre-seed round on an idea, yet you present a five-year, three-statement model. This is a misallocation of founder time. At this stage, your focus should be on a simple budget and a clear Use of Funds to get you to your MVP and first ten customers.
How to Apply This This Week
Model Your Core Unit of Growth: Before building a full P&L, model your customer acquisition funnel. Start with a top-of-funnel action (e.g., 1000 website visits). What percentage sign up for a trial? What percentage of trials convert to a paid plan? What is your average revenue per customer? This is the atomic unit of your growth engine. · Build a Hiring Plan: In a spreadsheet, map out a timeline of who you will hire and when (e.g., Month 1: 2 Engineers; Month 4: 1 AE). Apply a realistic, fully-loaded annual cost to each role. · Connect a Bottoms-Up P&L: Start your revenue projections with your current baseline. Layer on the new revenue generated by your new hires (e.g., an AE hired in Month 4 starts closing their first deals in Month 6 or 7). Build your expense forecast from your hiring plan and other key assumptions. · Create Your Use of Funds: Based on your fundraising goal, translate your operating plan into a simple allocation summary (Team, GTM, G&A/Buffer). Write a single sentence that connects the fundraising amount to your target milestone (e.g., revenue goal, product launch). · Pressure-Test Everything: Ask an experienced founder or angel investor to attack your model. Are your conversion rates realistic? Is your assumed ACV defensible? Is your CAC payback period under 18 months? Finding flaws now is free; finding them in a pitch is fatal.
Frequently asked questions
- How detailed should my underlying financial model spreadsheet be?
- For seed rounds, it should be detailed enough to show your work and allow investors to toggle your key assumptions. This typically means a monthly P&L for 3 years, a hiring plan, and calculations for revenue, COGS, and major OpEx buckets. A full three-statement model (P&L, Balance Sheet, Cash Flow) is usually overkill unless you have a complex business (e.g., hardware, inventory).
- What if I'm pre-revenue and pre-product? What financials do I show?
- Don't build a detailed revenue model. It's fiction, and investors know it. Instead, focus on your market size (TAM), your team, and a detailed 'Use of Funds.' Show how the capital you raise will be spent over 18-24 months to build the MVP, get your first design partners, or whatever your key milestone is before your seed round.
- What are the most common assumptions to include for a SaaS business?
- Focus on revenue and hiring drivers. For revenue, include average contract value (ACV), customer acquisition funnel conversion rates, churn rate, and net revenue retention. For costs, show your hiring plan by role and the fully-loaded cost per employee (typically 1.3-1.4x salary).
- Should I include a Balance Sheet and Cash Flow Statement in my deck?
- No. Keep your in-deck slides focused on the P&L summary and Use of Funds. The full three-statement model belongs in your data room for due diligence, which is standard for Series A and beyond, but less common at the seed stage.
- My revenue growth isn't a perfect "hockey stick." Is that okay?
- Yes, realistic is better than perfect. It's more credible to show growth that corresponds to your hiring plan. For example, revenue growth might be slower for the first 3-6 months post-raise as you hire and ramp up your sales team, then accelerate. This shows you understand the operational realities of scaling.
