Enter a previous and current value to instantly calculate growth rate (%), percentage change, difference, and multiplier. Percentage increase and decrease, plus month-over-month (MoM), year-over-year (YoY), quarter-over-quarter (QoQ), and week-over-week (WoW) growth all share the same formula, so this one calculator covers them all. Works for revenue, users, traffic, or any metric, entirely in your browser.

Growth Rate = (Current − Previous) / Previous × 100Growth rate, percentage change, percent increase, and percent decrease are different names for the same calculation. Each is (Current − Previous) / Previous × 100. A positive result is usually called an increase and a negative one a decrease, but the math is identical, so there's no need for a separate percentage increase calculator and percentage decrease calculator; this growth rate calculator handles both.
Only the label changes depending on which two values you compare. Whatever numbers you put in the previous and current fields, the calculator returns the change the same way.
The MoM, YoY, QoQ, and WoW growth figures common in business reporting are the same percentage-change calculation. MoM (month over month) compares last month with this month, YoY (year over year) compares last year with this year, QoQ (quarter over quarter) compares consecutive quarters, and WoW (week over week) compares last week with this week.
For example, with last month's revenue at 10,000 and this month's at 12,500, enter 10,000 as the previous value and 12,500 as the current value to get a MoM growth of +25%. Use last-year/this-year numbers for YoY, quarterly numbers for QoQ, and weekly numbers for WoW: no need to switch between a separate MoM, YoY, QoQ, or WoW calculator.
Alongside the percentage change, the calculator shows the absolute difference and the multiplier. The multiplier tells you how many times the previous value the current value is (e.g. 1.25×), which makes the size of the change easier to grasp. If the previous value is zero, the growth rate is undefined because it would divide by zero, so pick a non-zero starting point.
Use it with any metric: revenue, traffic, subscribers, conversions: to fill in the growth figures in a report or to check progress toward a goal. Every calculation runs in your browser and the numbers you enter are never sent to a server.
What it is, who it's for, how it works and why you'd use it.
A Growth Rate Calculator is a unified tool for quickly calculating growth rate, percentage change, and MoM, YoY, QoQ, and WoW growth. A growth rate calculator, MoM calculator, YoY calculator, QoQ calculator, WoW calculator, and percentage increase/decrease calculator all use the same (Current − Previous) / Previous × 100 formula, so entering a previous and current value shows the growth rate, change, difference, and multiplier on one screen.
It is for PMs, marketers, analysts, small business owners, and developers who measure changes in revenue, users, traffic, or any metric: especially anyone reporting monthly (MoM), yearly (YoY), quarterly (QoQ), or weekly (WoW) growth.
Enter a previous and current value and it applies (Current − Previous) / Previous × 100. A positive result is a percentage increase and a negative one a decrease; set the comparison period to last month, last year, last quarter, or last week to read it as MoM, YoY, QoQ, or WoW growth.
Instead of hopping between separate tools for growth rate, percentage change, and MoM/YoY/QoQ/WoW, you get an accurate number in one place with no manual math: saving time on reports and analysis.
