Loss Assessment Calculator
Free loss assessment calculator for condos: estimate your share of a master policy deductible and compare it to HO-6 loss assessment coverage limits.
By True Condo Cost editorial team · Editorial standards
A large master policy deductible can become a per-unit bill after a building claim. HO-6 loss assessment coverage may pay part of your share—if you bought enough limit and the charge qualifies.
Enter the master deductible (or building value and percent), unit count, and your HO-6 loss assessment limit to see uncovered exposure.
How to estimate manually
Use the inputs below as a worksheet. Enter your own figures from loan estimates, HOA resale documents, insurance quotes, and county tax records. Results vary by building and market.

Loss assessment calculator for condo buyers
This loss assessment calculator estimates your share of a master policy deductible when the association passes that cost to owners after a covered claim. It is not a quote engine and does not read your HOA documents automatically.
Searchers looking for a condo master policy deductible calculator usually want this math: total deductible divided by unit count, compared to HO-6 loss assessment limits on your quote.
Master deductible vs capital special assessment
Loss assessments tied to insurance deductibles are different from capital special assessments for roofs, garages, or reserve shortfalls. HO-6 loss assessment coverage may reimburse qualifying insurance-related charges up to your policy limit, subject to policy language.
Use the special assessment calculator when the board levies a repair project. Use this tool when minutes or insurance summaries describe a deductible pass-through after a wind, water, fire, or earthquake claim.
- Master deductible pass-through: often follows an insurance claim event
- Capital special assessment: reserve project or repair vote
- HO-6 loss assessment limit: user-entered from your quote
- Allocation method: equal split here; your CC&Rs may differ
What to pull from the resale packet
Request master policy declarations showing deductible type and amount. Wind, earthquake, and water deductibles may be flat dollar or percentage of building insured value. Note whether garage podiums share the same policy.
Compare the per-unit output to loss assessment limits on your HO-6 quote. Coastal and catastrophe-exposed buildings often need higher limits than inland stock with modest deductibles.
- Flat dollar deductibles: enter the amount shown on declarations
- Percentage deductibles: building insured value × percent ÷ unit count
- Named-storm or wind-only deductibles may differ from all-peril lines
- Garage and amenity levels sometimes carry separate flood or wind policies
How to use results before closing
If uncovered gap is large relative to your cash reserves, increase loss assessment coverage on HO-6 before binding, compare buildings, or budget the gap like a contingent assessment.
Pair results with the master policy deductible guide and loss assessment coverage guide for policy qualification details—not every association charge triggers HO-6 reimbursement.
When to rerun the calculator
Rerun when you receive updated insurance renewals in the resale packet, when comparing two buildings with different master deductibles, or when your agent quotes different loss assessment limits.
After a regional storm season, boards sometimes discuss deductible exposure in minutes even before a claim—useful context when choosing limits before closing.

Frequently asked questions
