Week Over Week Calculator

Calculate Week-Over-Week (WoW) growth rates, absolute velocity changes, and 4-week compounding projections.

Quick Definition & Answer

What is the Week Over Week Calculator?

Week-over-week (WoW) growth calculation measures short-term percentage changes in business metrics between consecutive seven-day operational performance intervals. It subtracts prior week metric totals from current week performance, dividing the difference by prior week totals and multiplying by one hundred. This equips growth marketers and operations managers with rapid feedback loops to detect emerging trends, monitor campaigns, and resolve performance dips.

Week-over-Week (WoW) growth measures the short-term percentage change in a business metric from one seven-day period to the next, serving as the essential velocity indicator for high-growth startups, e-commerce, and product teams.
