HOA Fee Increase Calculator

Every association budget cycle eventually surfaces the same uncomfortable math: expenses are rising faster than current fee collections, and the gap has to come from somewhere. Before a board can present a fee increase proposal to owners or vote to adopt a new budget, someone has to calculate what the increase actually means per unit per month, a number concrete enough to debate and communicate.

This calculator takes the annual budget shortfall and divides it equally across all units, then converts the result to a monthly per-unit figure. If you provide your current monthly fee, it also shows the new fee and the percentage increase, which is typically what owners care most about. The underlying math is straightforward, but having it calculated clearly makes board discussions more productive and owner communications more credible.

The calculator assumes an equal per-unit split. Associations where fees are allocated by unit type, square footage, or percentage of interest should adjust the shortfall figure accordingly, dividing the total shortfall by each unit's proportional share rather than the unit count.
