Year Over Year (YoY) Growth Calculator
Calculate Year-Over-Year (YoY) revenue growth percentage, absolute dollar expansion, and next-year compound projections.
What is the Year Over Year (YoY) Growth Calculator?
Year-over-year (YoY) growth calculation measures percentage expansion or contraction in corporate financial metrics across identical annualized calendar or fiscal periods. It subtracts baseline figures from the preceding year from current period results, dividing the net variance by the prior year baseline. This enables corporate executives and investors to evaluate underlying business growth trends while filtering out seasonal cyclicality across annual reporting cycles.
Year-over-Year (YoY) growth measures the percentage change in a business metric between two identical periods across consecutive years, neutralizing seasonality to assess long-term operational health.
