Condo Expenses Calculator
Free condo expenses calculator: estimate monthly mortgage, HOA, taxes, insurance, PMI, utilities, and assessment buffer in one payment.
Listings show mortgage payments, not the full bill. This condo expenses calculator adds association dues, insurance, property taxes, PMI, utilities, and an optional assessment buffer.
Use it to answer how much a condo costs per month with your own assumptions before you tour buildings or write an offer.

Your numbers
What this means
Enter your purchase price, loan terms, HOA dues, and other costs to see an estimated all-in monthly payment.
Assumptions and limitations
- PMI estimated at 0.75% of loan balance annually when down payment is under 20%.
- Property tax uses purchase price as assessed value unless you change it.
- Utilities and maintenance vary by unit size, age, and what HOA covers.
Frequently asked questions
- What is included in monthly condo cost?
- This condo expenses calculator adds mortgage principal and interest, property taxes, HOA dues, HO-6 insurance, utilities, interior maintenance, and an optional assessment savings buffer.
- How much does a condo cost per month?
- Enter your purchase price, loan terms, HOA dues, tax rate, and insurance quote to see an all-in monthly payment. Costs vary by building and location, so use your own figures rather than a generic average.
- Are HOA fees part of my mortgage payment?
- No. HOA dues are paid separately to the association, though lenders consider them in debt-to-income ratios.
- Should I budget for special assessments?
- Many buyers set aside extra monthly cash if reserve studies show underfunding or upcoming capital projects.
When this matters
- You are comparing listings that show different purchase prices but similar-looking monthly payments
- HOA dues or insurance quotes would push you over your comfortable budget
- You want one number that includes mortgage, tax, HOA, insurance, and owner-paid upkeep
- You are deciding between two buildings where one has lower HOA but higher insurance exposure
What this calculator does not include
- Live tax bills, insurance quotes, or HOA budgets from any database
- Lender approval, HOA questionnaire results, or project eligibility
- Future HOA increases unless you change the inputs yourself
- Home price appreciation or depreciation
- Income tax deductions for mortgage interest or property tax
- Selling costs, agent commissions, or capital gains tax
- Closing costs and cash due at settlement
- Move-in fees, transfer fees, or one-time association charges
See our methodology page for how each input is defined and how to interpret results.
Common questions
- Should I use the listing's HOA number?
- Use the figure from the current HOA budget or resale certificate, not an old listing. Dues change when insurance renews or reserves are replenished.
- Where do I get a property tax rate?
- Ask your agent or closing attorney how assessed value is set after purchase in your county. Use a rate that reflects your expected bill, not necessarily the seller's historical payment.
- Does this include special assessments?
- Only if you enter an assessment reserve or use the special assessment calculator separately. Pending assessments disclosed in resale documents should be modeled on their own.
Sources to verify before buying
Use this checklist during due diligence. Calculators help you plan; these documents tell you what a specific building actually costs.
- HOA budget and most recent financial statements
- Reserve study and percent-funded summary
- Master insurance policy declarations and renewal terms
- Board meeting minutes from the past 12–24 months
- Pending or approved special assessment notices
- County or municipal property tax estimator for the unit
- HO-6 insurance quote matched to master policy coverage
- Lender condo questionnaire or project approval status
Assumptions and limitations
- Outputs are planning estimates only, not quotes from lenders, insurers, or tax authorities.
- Actual HOA dues, insurance premiums, and tax assessments vary by building, location, and ownership status.
- PMI, special assessments, and reserve risk are modeled with simplified assumptions unless you enter your own figures.
- Always confirm numbers with association documents, your agent, and qualified professionals before making an offer.
