Sales forecast calculator
Month-by-month sales for the next year or more, from growth, last year’s pattern or store traffic.
A forecast repeats the assumptions you enter; it cannot know about new competitors, price changes or the economy. Estimates only, not financial, tax or legal advice.

How it’s calculated
Steady growth multiplies the first month’s sales by one plus the monthly growth rate for each month that follows. If you adjust for busy and slow months, each month is scaled by its seasonal percent; the percents are rescaled to average 100 so they shift sales between months without changing the yearly total.
From last year applies one growth rate to each of last year’s months, so the forecast keeps the same seasonal shape. The online store mode multiplies visitors by the conversion rate to get orders, and orders by the average order value to get sales.
Example
A business selling $20,000 in its first month and growing 3% a month sells about $283,841 over 12 months, ending near $27,700 a month.
A store with 20,000 visitors a month, a 2% conversion rate and a $60 average order sells $24,000 a month.
