HOA Reserve Funding Calculator
This HOA reserve funding calculator gives boards a quick, straight-line estimate of the annual reserve contribution needed to replace major components on schedule. List each reserve component with its replacement cost and useful life, enter your current reserve balance, and see an approximate percent-funded reading that many reserve studies use to gauge reserve health.
Percent funded compares your current balance to the fully funded balance. Many associations aim for 70% or higher to reduce the risk of special assessments.
How it is calculated
For each component, the annual contribution is its replacement cost divided by its useful life in years. The tool adds these together to estimate the total annual reserve contribution.
The fully funded balance is what an ideally funded reserve would hold today: each component's replacement cost multiplied by its age over its useful life, where age is useful life minus remaining life. Percent funded is your current reserve balance divided by that fully funded balance.
This is a simplified straight-line model. A formal reserve study also accounts for inflation, interest earned and component-level timing, so treat these figures as a planning estimate.
