Create 3-year financial projections for your business plan. Revenue, expenses, and profit forecast. Free business projection calculator.
Lenders and investors require 3-5 year financial projections — but most first-time entrepreneurs have no idea how to build them. The key is bottom-up projections based on realistic assumptions about customers, pricing, and costs — not top-down guesses like capturing 1% of a billion dollar market. Our calculator builds credible projections from your actual unit economics.
Bottom-up projection method: Start with your sales channel and realistic customer acquisition. Month 1: 10 customers at $200/month = $2,000 revenue. Month 3: 25 customers at $200/month = $5,000. Month 12: 80 customers at $200/month = $16,000. Year 2 with referrals and marketing: 200 customers = $40,000/month. Layer in costs against revenue. This is far more credible than saying you will capture 2% of a $10B market.
Mistakes that destroy credibility with investors: Hockey stick projections — flat for 18 months then sudden explosive growth with no explanation. Underestimating costs — forgetting taxes, benefits, infrastructure, and support. Overestimating conversion rates — assuming 10% free-to-paid when industry average is 2-3%. Ignoring churn — SaaS businesses that do not model customer attrition produce wildly optimistic revenue. Single scenario — always show base, optimistic, and pessimistic scenarios.
Step 1: Define your revenue model — how do customers pay you and how much. Step 2: Model customer acquisition — how many customers each month based on realistic channels. Step 3: Calculate monthly revenue. Step 4: List all costs by fixed and variable. Step 5: Calculate monthly profit or loss. Step 6: Project cash balance (cumulative losses show when you need funding). Step 7: Repeat for 36 months minimum.
Standard investor financial package: Income statement projection (P&L): monthly for year 1, quarterly for years 2-3. Cash flow statement: shows when you run out of money. Balance sheet projection: assets and liabilities. Key metrics by business type: SaaS: MRR, churn, CAC, LTV. E-commerce: revenue, gross margin, CAC. Unit economics: profit per customer or transaction.
Reality check: most startup revenue projections are off by 50-200% from actual results. Investors know this — they evaluate the logic and assumptions behind projections more than the specific numbers. Show conservative, base, and optimistic scenarios. Defend every assumption with data or logic. The most credible founders say their projections will be wrong and explain what metrics they will track to adjust.
