Term vs Whole Life Insurance Calculator
Estimate your annual term life insurance premium based on coverage amount, age, health rating, and policy term. Use this to budget for life insurance or compare the cost of different term lengths.
About this calculator
This calculator estimates the annual premium for a term life insurance policy. The formula is: Premium = coverage_amount × (age / 1000) × health_rating × (term_length / 20) × 0.15. Coverage amount sets the base exposure the insurer underwrites. Dividing age by 1,000 converts it to a decimal rate factor — older applicants pay proportionally more because mortality probability rises with age. The health_rating multiplier adjusts for risk class: preferred-plus policyholders (around 0.7) pay less than standard-risk applicants (1.0) or substandard-risk applicants (above 1.0). Dividing term_length by 20 scales the premium for the duration of coverage, since a 30-year term is priced higher than a 10-year term. The constant 0.15 is the actuarial rate factor tying these variables to a dollar premium.
How to use
Example: coverage = $500,000, age = 35, term length = 20 years, health rating = 0.9 (preferred). Step 1: age factor = 35 / 1,000 = 0.035. Step 2: term factor = 20 / 20 = 1.0. Step 3: Premium = 500,000 × 0.035 × 0.9 × 1.0 × 0.15. Step 4: = 500,000 × 0.035 = 17,500. Step 5: 17,500 × 0.9 = 15,750. Step 6: 15,750 × 1.0 × 0.15 = $2,362.50 estimated annual premium.
Frequently asked questions
How does age affect the cost of term life insurance?
Age is the single most influential factor in term life insurance pricing because mortality risk rises steadily with each passing year. In this model, age divides directly into the premium calculation, meaning a 40-year-old pays roughly 14% more than a 35-year-old for identical coverage. Insurers lock in your age at the time of application for the full policy term, so buying earlier provides guaranteed lower rates for the entire duration. Delaying a purchase by even five years can meaningfully increase total premium paid over the life of the policy.
What health rating should I enter and how does it change my premium?
Health rating is a multiplier reflecting your assigned risk class. Preferred-plus applicants — non-smokers in excellent health with clean family histories — typically use a value around 0.7 to 0.85. Standard applicants use 1.0. Those with managed health conditions, tobacco use, or elevated BMI may fall above 1.0. The lower your health rating multiplier, the lower your estimated premium. Insurers assign risk classes after a medical exam and review of your health history, so actual rates can vary from this estimate.
When does term life insurance make more financial sense than whole life?
Term life insurance is generally the better financial choice when you need coverage for a defined period — such as the years your children are dependents, or while you are paying off a mortgage. It provides a larger death benefit for a much lower premium than whole life. Whole life builds cash value and lasts your entire lifetime, but the higher premiums mean many policyholders could achieve equivalent wealth accumulation by buying term and investing the difference. Financial advisors often recommend term for most households with straightforward income-replacement needs.
