A revenue estimate is a projection of how much money a municipality expects to receive from each revenue source during a budget year. Estimating revenue requires analyzing historical trends, economic conditions, assessment growth, fee structures, and expected grants. Accurate estimates are crucial—overestimates create budget shortfalls requiring service cuts or tax increases, while underestimates may mean opportunities missed. Revenue estimates for major sources like property tax are relatively predictable, while grant funding and development charges may be more uncertain. Budget documents detail revenue estimates by source, and quarterly reports compare actual revenue against estimates to identify variances requiring attention.
