How to Use the HOA Reserve Fund Calculator
If you own a condo or live in an HOA community, your monthly dues usually include a long-term reserve fund contribution. This money is set aside in advance to cover major future repairs like roof replacement, elevator upgrades, and plumbing work, and the rate charged depends on your unit size and how old the building is. Enter your unit size, the building's age, and your target savings period to see a recommended monthly contribution and the projected balance.
Older buildings are more likely to need large-scale repairs soon, so associations typically charge a much higher per-square-foot rate for buildings over 20 years old compared to new construction under 5 years old. Actual rates set by your HOA board can vary based on the building's condition and its official reserve study, so treat this result as a general planning estimate.
If your actual HOA dues include a reserve contribution far lower than this estimate, your association may be underfunded, which raises the risk of a special assessment when major repairs come due. If the rate looks unusually high, it is worth reviewing the reserve study to confirm the funds are being used appropriately.
Frequently Asked Questions
Most condo and HOA associations require owners to contribute monthly based on unit size to fund major repairs like roofing, elevators, and plumbing replacement.
Older buildings face upcoming large-scale repairs sooner, so associations raise the per-square-foot rate to build up reserves faster before major work is needed.
