The Formula
Revenue(month n) = Current Revenue × (1 + Monthly Growth Rate)^n

10% monthly growth is aggressive but achievable for early-stage businesses. Realistic growth rates for established Nigerian SMEs are typically 3–8% per month. At 5% monthly growth, the same business generates ≈₦8.1M over 12 months.
FAQ
Early-stage startups (0–12 months): 10–20% monthly growth is possible but not sustainable long-term. Growth-stage businesses (1–3 years): 5–10% monthly is strong. Established SMEs: 2–5% monthly (24–60% annually) is excellent. Keep in mind that Nigeria's high inflation rate (~25%) means you need to grow revenue faster than inflation just to maintain real purchasing power. A 30% annual revenue growth in a 25% inflation environment is only 5% real growth.
This calculator uses monthly compounding, which is more realistic for Nigerian businesses that track performance monthly. Note the difference: 10% monthly growth = 214% annual growth (not 120%). Use monthly rates for short-term planning (1–2 years). For long-term projections (3–10 years), annual rates are more intuitive and the numbers are less sensitive to compounding assumptions. Always document your assumptions when sharing forecasts with investors or banks.
Start with your key drivers: number of customers, average order value, and purchase frequency. For example, if you have 100 customers each spending ₦5,000 monthly, revenue = ₦500,000. To grow 10% monthly, you might need to: add 10 new customers, increase average spend by ₦500, or get existing customers to buy more often. Link your growth target to specific, measurable actions rather than hoping the number will happen organically.
