Methodology

How the calculators work

Every Sharpmonk calculator runs a deterministic formula, entirely in your browser: a base rate for the policy type, adjusted by a fixed set of multipliers for the factors you enter (age, coverage amount, deductible, regional risk, and so on). Nothing is looked up from a live insurer feed or a machine-learning model — the same inputs always produce the same output, and you can see exactly which factor moved the number by how much.

Each calculator page has its own “Methodology and source notes” panel listing the exact inputs, formula, assumptions, and cited sources for that tool. This page covers the approach that's common across all of them.

Where the numbers come from

The rating factors used (age bands, tobacco surcharges, deductible credits, coverage-tier multipliers, regional risk adjustments) are generic patterns that are broadly documented by industry and regulatory sources — the Insurance Information Institute, the National Association of Insurance Commissioners (NAIC), and HealthCare.gov, among others. They are notpulled from any specific insurer's filed rate tables. See the Disclaimer for what that means for how you should use the output.

Assumptions and limits

• Inputs are treated as exact, known values — none of the calculators model uncertainty or ranges.
• State-specific regulation, credit-based insurance scores, and insurer-specific underwriting are not modeled.
• Formulas use illustrative rate levels chosen to be broadly representative, not tuned to any particular market or time period beyond general accuracy.
• Where a calculator makes a simplifying rule-of-thumb assumption (for example, the whole-life-vs-term multiplier), that assumption is called out explicitly in its methodology panel.

Review cadence

Formulas and rate assumptions are reviewed when a calculator is first published and whenever the underlying industry guidance they're based on changes materially (for example, a shift in ACA age-rating rules). The methodology panel on each calculator page reflects the current version of that tool's formula.

Spot something off?

If a formula looks wrong or a source link is broken, use the contact page— corrections get made directly in the calculator's methodology panel once verified.
