About this tool
Our Revenue Forecast Calculator is the most comprehensive free tool for projecting future business revenue. Revenue forecasting is essential for business planning, fundraising, budgeting, and strategic decision-making. Whether you're preparing a business plan for investors, setting sales targets, planning expenses, or evaluating growth scenarios, accurate revenue projections provide the foundation for sound financial management. This calculator implements multiple forecasting methods including straight-line growth, compound growth, and trend-based projections, giving you a range of scenarios from conservative to aggressive.
The calculator uses compound annual growth rate (CAGR) methodology for realistic projections. Simple percentage growth compounds each period - 10% monthly growth doesn't add $10K each month if starting at $100K, it grows exponentially: $110K, $121K, $133.1K, etc. This compounding effect is crucial for accurate long-term forecasts. The tool projects revenue month-by-month or year-by-year, showing cumulative totals and period-over-period growth. You can model different scenarios: conservative (3-5% monthly growth), moderate (5-10%), aggressive (10-20%), or custom rates based on your specific situation.
Advanced features include seasonality adjustments for businesses with predictable seasonal patterns (retail holiday peaks, tax preparation services, tourism, etc.). You can specify monthly multipliers to reflect your business cycles - perhaps December is 200% of average while February is 60%. The calculator also handles one-time revenue events like large contracts, product launches, or expansion into new markets. It computes key metrics including average revenue per period, growth rate sustainability, and the revenue run rate (annualized revenue based on recent performance).
Revenue forecasting requires balancing optimism with realism. The calculator helps you test assumptions and understand implications. If you forecast 15% monthly growth, you'll see that $100K today becomes $547K in 12 months and $5.5M in 24 months - helping you evaluate if that's realistic given market size, competition, and resources. The tool is completely free, requires no registration, and works entirely in your browser. Perfect for startups, growing businesses, CFOs, entrepreneurs, and anyone creating financial projections or business plans.

FAQs
How do I forecast revenue for a new business?
For startups without revenue history: 1) Bottom-up approach: Calculate unit sales × price per unit. Estimate customers, conversion rates, average purchase value. 2) Market-based: Research comparable businesses, apply industry averages to your target market. 3) Sales pipeline: Project conversion rates and deal sizes through sales stages. Start conservative and adjust as you gather real data. First year projections are often wrong - plan for 50-70% of forecast. Focus on assumptions and test them quickly.
What is a realistic revenue growth rate?
Growth rates vary dramatically by stage and industry. Startups: 10-20% monthly early on (unsustainable long-term). Established small businesses: 10-30% annually. Mid-size businesses: 5-15% annually. Large companies: 2-10% annually. SaaS targets: 3x year-over-year early stages (Triple, Triple, Double, Double). Sustained 100%+ annual growth is extremely rare. Be realistic - 5% monthly growth means 80% annual growth, 10% monthly = 214% annual. Test assumptions against market size and competition.
Should I create multiple revenue scenarios?
Yes, always create at least three scenarios: Conservative (pessimistic but viable), Base Case (most likely), Aggressive (optimistic but achievable). Typical approach: Conservative = 50% of base case growth, Aggressive = 150% of base case. Use for: fundraising (show investors realistic upside), planning (make decisions based on conservative case), goal-setting (target aggressive case). Update scenarios monthly with actual results. Most businesses track between conservative and base case, rarely hit aggressive consistently.
How do I account for seasonality in forecasts?
Identify seasonal patterns from historical data or industry norms. Calculate monthly revenue as % of annual average. Example: Retail might be 60% in Feb (slow), 180% in Dec (holidays). Apply these multipliers to base forecast. B2B often sees Q4 budget-flush, Q1 slow start. Tourism peaks in summer. Tax prep in spring. Even growth businesses have seasonal variations. Model 2-3 years of history to identify patterns. Seasonality affects cash flow planning - build reserves for slow months, prepare inventory/staff for peaks.
What is revenue run rate?
Run rate annualizes recent revenue to project annual performance. Formula: Most Recent Month × 12 or Most Recent Quarter × 4. Example: $100K revenue last month = $1.2M annual run rate. Pros: Simple, reflects current performance. Cons: Assumes no growth, ignores seasonality, misleading for volatile businesses. Use for: quick estimates, investor updates, mature businesses. Don't use for: growing companies (understates), seasonal businesses (over/understates depending on season). Better: calculate based on trailing 12 months (TTM) revenue.
How often should I update my revenue forecast?
Update monthly for first 2 years, then quarterly for established businesses. Each update: Compare actual vs forecast, analyze variances (why different?), adjust future periods based on learnings, test assumptions. Major updates needed when: launching products, entering markets, losing/gaining major customers, economic changes, competitive shifts. Roll forecast forward - always maintain 12-month forward view. Track forecast accuracy to improve over time. Poor accuracy signals need to revisit assumptions or forecasting method. Continuous improvement is key.
