Sales Forecast Calculator

About this calculator

A simple sales forecast projects future revenue by applying a steady growth rate per period to a current sales figure, compounding it forward period after period — the same mathematical structure as compound interest, applied to revenue instead of a savings balance. It's the most basic forecasting method, useful when a business has a fairly consistent, trackable growth trend rather than highly seasonal or volatile sales.

This calculator takes your current sales figure, a growth rate, and a number of periods, and projects what sales would reach if that rate held steady throughout. Business owners and planners use this projection to set revenue targets, size staffing and inventory needs ahead of growth, or build a baseline case to compare against more detailed, assumption-heavy forecasts.
