CDD Assessment & Housing Budget Calculator
Turn a supplied annual CDD assessment into a monthly budget equivalent. Compare known housing costs without double counting; no parcel or loan certification.
What This Calculator Does
Use two inputs: a known annual CDD total and an optional known monthly housing base that excludes it. Annual ÷ 12 is a budget equivalent, not a monthly billing schedule. A blank housing base remains unknown; a known 0 is different. Combined cost and the CDD share are available only with a known base. No property price, future assessment or approval is inferred.
Who Is This For
Buyers, owners and real estate professionals budgeting from actual assessment and housing documents. Government pages provide billing context, not a parcel quote; loan and closing requirements remain separate.
How It Works
Enter the yearly CDD total (0 if it is 0). If you know it, add your monthly housing cost without this CDD, taking out any part already in escrow; otherwise leave it blank. Tick the confirmation and read the three results, including when one is unknown or can't be shown. The exact figures before rounding show the same calculation; they are not extra bills.
Frequently Asked Questions
Which CDD amount should I enter?
Use the supplied annual total for the relevant parcel, counted once. If that total already includes debt service and operations/maintenance, do not add those components again. For an annual assessment of US$2,400, the monthly budget equivalent is US$200. The calculator does not retrieve the amount or prove that a parcel owes it.
Does annual CDD divided by 12 mean twelve monthly bills?
No. It is a budget equivalent only. Actual collection may appear on a property-tax bill; verify the relevant documents. There is no payment schedule, 30-year total, bond payoff date or future-fee forecast. Ending a debt-service portion does not establish that continuing operating charges will become zero.
What's the difference between an unknown housing cost, a housing cost of 0 and both amounts at 0?
A blank housing cost means unknown, so the monthly total and the share stay unknown, not 0. With a yearly CDD of $1,200 and a housing cost of 0, the total is $100 and the share is 100%. With both amounts at 0, the total is $0 and there is no share to show, because 0 can't be divided by 0. A yearly CDD of 0 with a $3,000 housing cost gives a $3,000 total and a 0% share; entering 0 doesn't prove the property has no CDD.
What does the CDD percentage measure?
It is the CDD budget equivalent divided by the combined entered monthly housing budget, times 100. With annual CDD US$2,400 and non-CDD housing US$3,000, monthly CDD is US$200, combined US$3,200 and share 6.25%. It is not a percentage of property price, a property-tax rate or an affordability/loan verdict. The base includes only the housing components you actually supply.
What if the tax or escrow estimate already includes this CDD?
When inclusion and amount are known, reconcile the CDD monthly equivalent out of the housing base before adding it once. If US$3,200 already includes US$200 CDD from annual US$2,400, enter US$3,000: combined remains US$3,200, not US$3,400. Check actual escrow/bill documents; the calculator does not detect inclusion. If the non-CDD base is unknown, leave it blank instead of inventing a certified total.
How are fractional cents and tiny shares handled?
Entries keep cents, but yearly ÷ 12 can produce fractions of a cent. A yearly $0.01 gives a positive monthly amount of $1/1200, not zero. Any positive amount under $0.01 or share under 0.0001% is still shown as more than zero. Other amounts are rounded to the nearest cent and shares to four decimal places. The share is calculated from exact amounts, and a rounded monthly figure × 12 is not the exact yearly bill.
What input ranges and conditions apply?
The yearly CDD is required, from $0 to $2 billion. The housing cost is optional: either unknown or an amount in the same range, without this CDD; 0 means zero, not missing. Negative or unreadable entries are rejected, never turned into 0. These are form limits, not district or lender rules; the monthly total is not capped.
What do the government sources establish?
Miami-Dade Property Appraiser and Florida Department of Revenue pages were read October 3, 2026 for non-ad-valorem billing context: CDD charges may appear on property-tax bills and are not property-value percentages. The saved September 30 arithmetic baseline is separate, not a historical tariff. No Miami-Dade, Broward or Palm Beach parcel amount, escrow treatment, future charge or eligibility is certified. No universal seller-disclosure duty is asserted; ask the relevant closing/legal professional.
