A positive number is annual growth; a negative number means this year's value is lower than last year's.
What is a yearly percentage increase calculator?
A yearly percentage increase calculator measures how much a value has grown from one year to the next, expressed as a percentage of last year's figure. It answers the question: by what percentage did this grow year over year? Use it for revenue, traffic, costs, population, or any metric tracked annually.
The formula is ((this year − last year) / last year) × 100. The annual change is divided by last year's value, so the result is always relative to the previous year. The yearly percentage increase calculator applies this formula instantly and shows the annual growth rate plus the absolute change.
Year-over-year percentages are the standard way to report annual growth because they are comparable across years and across very different scales. A 12% yearly increase means the same thing whether the base is 10,000 or 10 million, making it easy to spot trends and compare performance against targets or inflation.
