HOA Budget Calculator
Add up your association’s annual operating expenses and reserve contribution, and this calculator works out the monthly assessment each unit needs to pay. It also accounts for two things most quick calculators skip: delinquencies and non-assessment income.
Your annual budget
Enter total annual dollars for each category. Leave a category blank if it does not apply.

How to use this calculator
Count your units
Enter the number of assessable units or lots. If your documents assign dues by percentage of ownership rather than an equal split, use this result as the community-wide average and then apply your allocation schedule.
Enter annual expenses
Work from last year’s actuals, then adjust each line for known changes: insurance renewals, a new landscaping contract, utility rate increases. Put your reserve contribution in its own line.
Adjust and review
Add any non-assessment income and a realistic delinquency rate. The result is what you need to bill per unit to fully fund the budget you entered.
What belongs in each category
Landscaping and grounds
Mowing, irrigation, tree trimming, mulch and seasonal color, pest and fertilizer treatments, and grounds contract labor.
Insurance
Property and general liability, directors and officers, fidelity or crime coverage, umbrella, flood and windstorm where applicable, plus workers compensation if the association has employees.
Utilities (common areas)
Electricity for lighting and amenities, common water and sewer, irrigation water, trash collection, and any bulk cable or internet contract the association carries.
Maintenance and repairs
Routine and unplanned upkeep of common elements: pool service, elevator contracts, painting touch-ups, roof and gutter repairs, janitorial, HVAC service on common systems.
Management fees
The management company’s base fee plus any contracted extras. Self-managed associations may still have bookkeeping, payroll, or portal software costs to record here.
Administrative and legal
Attorney fees, audit or tax preparation, annual state filings and registered agent fees, mailings and postage, meeting costs, banking and payment-processing fees.
Reserve contribution
The amount transferred each year into reserves for major replacements such as roofs, paving, pool resurfacing, and painting. This should come from a current reserve study, not a round number.
Other expenses
Anything that does not fit above: security patrol or gate service, amenity staffing, community events, bad-debt write-offs you handle as an expense rather than a delinquency rate.
Four things to check before you adopt the budget
Start with actuals, not last year’s budget. Budgeting off a prior budget compounds whatever was wrong with it. Pull the year-end financials and compare each line’s actual spend to what was budgeted, then explain any gap over roughly 10% before you carry it forward.
Make sure the reserve line traces to a study. A reserve contribution that was set years ago and never revisited is the most common source of a surprise special assessment. Most associations refresh the study every three to five years, with an update between full studies. If your reserve line is a round number nobody can source, that is worth raising.
Budget delinquency honestly. If you historically collect 96% of what you bill, budgeting as though you will collect 100% leaves a shortfall every year. The calculator grosses up the assessment so the collected amount covers the budget.
Check what the increase looks like to an owner. A budget that pencils out but lands as a 22% dues increase will not pass without explanation. Bring the category breakdown to the meeting so owners can see which lines actually moved.
Frequently asked questions
How much should an HOA keep in reserves?
There is no single correct number, because it depends entirely on what your community owns and how old those components are. A high-rise with elevators, a roof, and a parking structure needs a far larger reserve than a small subdivision that maintains a sign and an entrance. What matters is that the contribution comes from a reserve study that inventories your components, their remaining life, and their replacement cost. Percentage-of-budget figures are useful only as a sanity check on that study, never as a substitute for it.
Does every unit pay the same amount?
Often, but not always. Many declarations allocate assessments by percentage of ownership interest, square footage, or unit type rather than an equal split. This calculator divides evenly, so if your documents allocate differently, treat the result as the community-wide average and apply your allocation schedule to it.
What is the difference between the operating budget and reserves?
The operating budget covers recurring, in-year costs such as landscaping, insurance, and utilities. Reserves fund the eventual replacement of major components that wear out over many years. Operating money that is quietly used for a reserve-type expense is how associations end up underfunded without noticing.
Can the board raise dues without an owner vote?
That depends on your governing documents and your state’s statutes. Some declarations cap how much the board can raise assessments in a year without membership approval; others let the board adopt the budget outright subject to an owner veto process. Check your declaration and bylaws, and confirm the notice and meeting requirements in your state before adopting an increase.
Where do special assessments fit in?
They do not belong in this calculator. A special assessment is a one-time charge for a specific purpose, typically because reserves were insufficient. Enter only your regular annual budget here. If you are consistently relying on special assessments, the reserve contribution line is the one to examine.
This calculator is an educational estimating tool. It does not produce a statutory budget and it is not accounting, legal, or investment advice. Adopt budgets with your association’s accountant, reserve analyst, and attorney, and follow the notice and approval procedures in your governing documents and state law.
