How to calculate sales growth
Sales growth measures the change in your revenue between two periods, usually month over month, quarter over quarter, or year over year. The sales growth rate formula is:
Sales growth rate % = (Current sales − Previous sales) / Previous sales × 100
Step 1: Identify current period sales
Total the revenue for the period you want to measure.
Step 2: Identify previous period sales
Find the revenue for the prior period of the same length so the comparison is fair.
Step 3: Apply the formula
Subtract previous from current, divide by previous, and multiply by 100 to get the percentage. A positive result is an increase; a negative result is a decline.
Worked example
Say your plumbing business booked $100,000 in the previous quarter and $125,000 this quarter. Enter $125,000 as Current Period Sales and $100,000 as Previous Period Sales:
- Total Sales Growth = $125,000 − $100,000 = $25,000
- Sales Growth Rate = ($25,000 / $100,000) × 100 = 25%
A 25% quarter-over-quarter increase is a strong result for an established service business.
