Contents, not the building
For renters, the “sum insured” is your belongings, not the building. A luxury building doesn’t automatically mean a higher contents limit—your stuff drives it.

How This Calculator Works
Release Updates
- Added Quick vs Detailed input modes so first-time users can start with essentials.
- Added presets (Typical renter, Condo owner, Budget cover, Higher protection) for faster setup.
- Added impact labels and collapsible advanced sections to make weighting clearer.
- Added confidence context that explains why the estimate range widens for certain risk profiles.
This tool estimates an annual premium using a transparent model: base premium, multiplied by risk factors, plus optional add-ons, then tax.
- Start with Quick mode: set unit type, contents value, location risk, claims, excess, and tax.
- Use Detailed mode if needed: refine building, security, flood/crime, liability, and add-ons.
- Read the breakdown table: each line shows the value and multiplier/cost used.
- Interpret confidence: the range expands when risk signals (like flood risk or claims) increase uncertainty.

🏢 5 Fun Facts about Apartment Insurance
Condo walls-in
In many condo/HO-6 policies, you cover “walls-in” improvements (floors, cabinets). The master policy usually covers the shell—know where the handoff is.
Boundary lines
Protection class still matters
Distance to hydrants, alarms, and sprinklers affects pricing even in multi-story buildings. Fire protection scores don’t just apply to standalone homes.
Fire factor
Liability is the sleeper
Personal liability often costs little but can carry high limits. A small add can jump from a modest to a robust liability limit for pennies per day.
Big value
Scheduled items dodge sublimits
Jewelry, bikes, or collectibles often have sublimits. Scheduling them can raise coverage and sometimes remove deductibles for those items.

Apartment / Flat Insurance — What Each Value Means (and how we estimate)
Apartment insurance (often called renters insurance for tenants or condo/leasehold (HO-6) for owners) typically covers Contents (your belongings), Personal Liability, and for owners, certain “walls-in” improvements. Our estimator is educational: it uses a transparent base premium and applies clear multipliers for building features, location hazards, claims, and policy choices. It is not a quote or advice.
Your cover
- Contents value (sum insured): The replacement cost for your belongings (furniture, electronics, clothing). Higher sums increase the premium. In our model this scales gently: small increases near typical ranges change price modestly; very high sums add more.
- Improvements / Betterments (walls-in): For condo/leasehold owners, this is the value of upgraded floors, cabinetry, fixtures you are responsible for beyond the building’s master policy. We apply a soft uplift when this value rises.
- Personal liability limit: Protects you if you accidentally injure someone or damage their property. We apply a small multiplier for higher limits (coverage is cheap relative to the protection offered).
Building & security
- Building type (low/mid/high-rise): Different structures have different loss profiles (fire protection, water propagation, escape). We apply a mild factor rather than a steep jump.
- Unit floor level: Basement/ground floors tend to carry more theft and water risk; mid/high floors may have lower theft/flood exposure but can see water-leak propagation from above. The multiplier reflects these trade-offs.
- Sprinklers: Automatic sprinklers typically reduce fire severity. We model a discount when present.
- Security: From standard locks to gated entry or concierge/door staff + CCTV. Better security earns a discount.
Location & claims
- Overall location risk: A composite signal (building area, local perils). We apply a modest up/down factor.
- Flood risk: Lower floors and certain zones price higher, even when flood might be a separate policy in your region. In this tool it’s a pricing signal only.
- Theft / crime risk: Higher-crime areas generally raise theft-related losses; we apply a surcharge accordingly.
- Claims in last 5 years: Prior losses raise risk for a period; our model adds a step-up per claim.
Policy settings
- Excess / deductible: The amount you pay first on a claim. Selecting a higher excess reduces the premium (we cap the reduction to keep things realistic).
- Optional add-ons: Accidental damage, water leak/backup, valuables/jewellery riders, portable electronics add flat costs. For condo/leasehold owners, loss assessment helps with your share of master-policy deductibles; we add a small fixed amount for this option.
- Tax (e.g., IPT/VAT): Applied to the subtotal after add-ons to obtain the estimated annual premium.
How the estimator calculates
We start with a base premium representing a typical tenant in a mid-rise building with average risks. We then multiply by factors for contents value, improvements (if any), building type, floor level, sprinklers, security, location (overall/flood/crime), claims, liability limit, and your chosen excess. Optional extras are added as flat amounts, and then a tax line is applied. The output shows a midpoint estimate and a ±10% range to reflect real-world variability.
Important: Real insurers use detailed postcode/geocoding, building construction data, association documents, loss history databases, eligibility rules and minimum premiums. This tool is for learning and budgeting only; always review policy wordings, exclusions, limits, and endorsements before buying.
