Renters Insurance Calculator
This calculator estimates recommended contents (personal property) coverage, a suggested liability limit, and a rough premium range for renters insurance. It supports a fast one-line total or a more precise itemized inventory total.
Results are illustrative and intended to help you choose coverage levels to discuss with insurers. This tool does not replace official insurer quotes or state-specific underwriting rules.

Visualization
Methodology
Coverage recommendations are based on your entered belongings value scaled by a replacement-cost multiplier to reflect whether you seek replacement cost or actual cash value protection.
Estimated premiums are produced using a simple actuarial proxy: a base rate per $1,000 of coverage adjusted by location risk, security features, underwriting tier, and deductible. This proxy is for comparison and calibration only.
We follow software and data-handling best practices informed by standards bodies. For risk management and data security guidance see NIST and ISO references in the citations.
Worked examples
Example A: $20,000 belongings, replacement cost, $500 deductible, medium risk → recommended contents coverage $20,000, liability $100,000, estimated annual premium around the calculated output.
Example B: Itemized inventory totaling $50,000 with advanced security → recommended contents coverage $50,000, liability $25,000 (subject to minimum), premium adjusted down by security multiplier.
F.A.Q.
Is this a binding quote?
No. Outputs are estimates for planning only. Insurer quotes depend on underwriting, local law, prior claims, and additional endorsements.
Should I choose replacement cost or actual cash value?
Replacement cost tends to cost more but provides funds to replace items at current prices. Actual cash value pays depreciated value. Use the replacement-cost multiplier to model either choice.
Why do multipliers look numeric strings in select fields?
Select option values are represented as strings in the form; the calculation engine coerces these to numbers for multipliers. This is an implementation detail and does not require action from you.
How accurate are the premium estimates?
Estimates are approximate. Real premiums vary by insurer pricing models, state regulations, discounts, endorsements, and individual risk factors. Use results to set coverage targets and obtain formal quotes.

Semantic versioning
- MAJOR: Calculation outputs can change for the same inputs (formula, rounding policy, assumptions).
- MINOR: New features or fields that do not change existing outputs for the same inputs.
- PATCH: Bug fixes, copy edits, or accessibility changes that do not change intended outputs except for previously incorrect cases.
Review protocol
- Verify formulas and unit definitions against primary standards or datasets.
- Run golden-case regression suite and edge-case suite.
- Record reviewer sign-off with credentials and scope.
- Document assumptions, limitations, and jurisdiction applicability.
Assumptions & limitations
- Uses exact unit definitions from the Fidamen conversion library.
- Internal calculations use double precision; display rounding follows the unit's configured decimal places.
- Not a substitute for calibrated instruments in regulated contexts.
- Jurisdiction-specific rules may require official guidance.
