Landlord Insurance Calculator

Estimate rental property insurance costs including dwelling, liability, and lost rent coverage.

About this calculator

The Landlord Insurance Calculator estimates a rental property's annual and monthly premium starting from a base rate per $1,000 of Property Replacement Value, then applies four adjustment multipliers for Property Age, Number of Units, Deductible, and Liability Coverage. Property Replacement Value is by far the most sensitive input, since the entire premium scales directly with it before any multiplier is applied. Property Age uses a step-function multiplier rather than a smooth curve — 1.0x for properties 15 years old or younger, 1.15x from 16 to 30 years, and 1.3x above 30 — which means small adjustments near a typical mid-range age (like the default of 20 years) don't move the premium at all until you cross one of those two breakpoints, even though age clearly matters once you do cross one.

Monthly Rent per Unit, by contrast, genuinely has no effect on the premium in this model at any value — it only feeds the separate Lost Rent Coverage and Insurance % of Rent Income outputs, which reframe the same premium against your rental income rather than changing what the premium itself is. This calculator produces a planning estimate from simplified rate multipliers, not a real quote — actual landlord (dwelling fire, DP-3) policy premiums vary by insurer, location, construction type, and claims history far more than the four factors modeled here.

How to Use This Calculator
  1. Enter the rental property's dwelling replacement cost.
  2. Input your monthly rental income for loss-of-rent coverage calculation.
  3. Set the desired liability coverage limit.
  4. Review the estimated annual landlord (DP-3) policy premium.
  5. Landlord policies cover tenant-caused damage and liability — add umbrella coverage for multi-unit properties.

Frequently Asked Questions

What does landlord insurance cover that homeowners insurance doesn't?

Landlord insurance (often called a DP-3 or dwelling fire policy) is built for a property you rent out rather than live in, so it covers loss of rental income if the property becomes uninhabitable after a covered event, and its liability coverage is written to address tenant-related claims rather than a homeowner's own household. A standard homeowners policy typically excludes or limits coverage once a property is rented to tenants, which is why this calculator's estimate applies a higher base rate than a comparable owner-occupied home would carry.

How does property age affect my premium?

Property Age applies as a step-function multiplier rather than a smooth scale: properties 15 years old or younger get a 1.0x multiplier, properties 16 to 30 years old get 1.15x, and properties over 30 years old get 1.3x. That means two properties aged 20 and 28 get the identical age multiplier despite the 8-year gap, while a property aging from 30 to 31 crosses into a higher tier and sees a real premium jump.

Does the number of units in my property change the premium?

Yes — Number of Units applies its own multiplier on top of the base premium: 1.0x for a single unit, 1.1x for two units, 1.2x for three to four units, and 1.4x above four units, reflecting the added liability and claims exposure of a larger multi-unit property. This is separate from Monthly Rent per Unit, which does not affect the premium at all in this model.

Why does raising my deductible lower my estimated premium?

A higher deductible means you're agreeing to cover more of any claim out of pocket before the insurer pays, which reduces the insurer's expected payout on smaller claims and is reflected here as a discount multiplier — 0.9x at a $1,000+ deductible and 0.8x at $2,500 or higher, compared to the 1.0x baseline below $1,000. The tradeoff is that a higher deductible also means more of your own money at risk if you do need to file a claim.
