Condo Cost Calculator: HOA Fees and Assessments
Add your condo's regular quoted HOA dues to your unit's unpaid assessment and see next-12 cash kept apart from the starting run rate.
What This Calculator Does
This condo cost calculator shows what your unit owes the association from the next monthly bill on. That means the regular dues you were quoted plus what's left of your special assessment, split to the exact cent. You get cash for the coming 12 periods and, separately, your first bill annualized. It won't total every ownership cost or test legal compliance.
Who Is This For
Use it if you're buying or own a Florida condo, or you're the agent on the deal, and you need to check on paper what a unit pays in dues, what's still owed on its assessment and over how many payments. Work from the association's current records and your purchase and closing documents, not from a guessed building-wide levy or a reserve charge nobody has billed yet.
How It Works
Enter your usual monthly HOA dues, leaving this assessment out. Enter what's still unpaid on the unit's assessment, or 0 if nothing is. Reserve contributions already in the dues stay there and aren't added again. If something is still owed, spread it over 1–120 whole payments. If there's no assessment, the tool schedules no payments. The purchase price is optional and may be left blank. Compare the first bill, the coming 12 months, the monthly amount, the final payment and any balance left. Confirm the association's actual payment schedule separately.
Frequently Asked Questions
What belongs in the HOA field versus the assessment balance?
The HOA field takes the regular monthly charge the association quoted you, without this assessment. Reserve contributions built into those dues stay in HOA, so don't enter them as a separate charge. The assessment field takes what your unit still owes as of the coming billing period. That isn't the levy for the whole building. It also isn't the original total if some of it has been paid. Both fields need an amount, even if it's 0. Nothing is filled in for you: no price, fee or month. Your mortgage, your own property tax and insurance, and other ownership costs stay out.
Why isn't the next-12 budget the same as the initial run rate?
They measure different things. The run rate is simply your first monthly bill times 12. The next-12 figure totals the payments actually modeled across the coming 12 periods. Example: a $1,000 HOA plus a $12,000 assessment balance, split into six payments. The first bill comes to $3,000, which makes the run rate $36,000. Over the next 12 periods, though, you pay $24,000, since the assessment ends after the sixth payment. These are sample inputs, not typical fees. The count starts at your next billing period, not in January, and doesn't follow a calendar or tax year.
How are the cents split across payments?
What remains is split in whole cents by the number of payments, and every share is rounded down to the cent. The leftover cents go one at a time to the earliest payments. That way the payments total exactly the balance, and the last payment is never negative. For example, $1 across three payments becomes $0.34, $0.33 and $0.33. With a tiny balance, the last non-zero payment can come early: if one cent is spread over 120 payments, it falls on the first payment, and the rest are $0. Your association's actual terms may differ.
What happens if there's no assessment, or you don't know the price?
Enter 0 for the assessment and its payments and balance show $0, with no assessment months and no final payment listed. Your regular HOA dues still appear. Leave the price blank and no price percentage appears, instead of 0%. Any price you enter must be above $0: zero, negative amounts and fractions of a cent are refused, not read as blank. The percentage puts the next 12 months of association costs next to the price. It's for context only, not a return, an affordability test, an appraisal or an approval.
Does the calculator decide SIRS, reserve waivers or future assessments?
No. Florida's reserve, SIRS and milestone inspection rules come with conditions and exceptions, and the model doesn't apply them. It won't infer coverage, a waiver or a pause from a building's traits, and it doesn't set a legal deadline, judge compliance or name a fee on that basis. Ask for the current budget, the assessment notice or payment plan for your unit, and whichever reserve or inspection documents apply. If the HOA dues include a reserve line, it isn't added again. The linked statute and DBPR references help with your due diligence. They can't confirm every future amendment, and they don't calculate the charge the law requires for a unit.
What should a buyer check, and where does the model stop?
Who pays, first. The contract, the association and the closing documents settle who pays the assessment and how buyer and seller split costs, so review them with your professionals. The model doesn't rule on prorations or legal liability. Ask whether the real plan carries interest, fees or irregular dates, because none of those is modeled. Assessments run on 1 to 120 whole payments, and an entry of 12.0 counts as 12 payments, not 120. No single amount can exceed $2 billion, and any result over $50 billion won't display. The calculator sets those limits; the association doesn't. Dues stay flat throughout the model, so enter dues changes or future assessments as new inputs or budget them separately.
