Term Life Insurance Premium Calculator
Estimate your annual term life insurance premium based on age, coverage amount, term length, health rating, and smoking status. Use this when shopping for life insurance to benchmark costs before speaking with an agent.
About this calculator
Term life insurance premiums are driven by four core risk factors: your age, the coverage amount you need, how long the policy lasts, and your health profile. The formula used here is: Annual Premium = (coverageAmount / 1000) × (0.5 + (age − 20) × 0.08) × (1 + (termLength − 10) × 0.02) × healthRating × smokerMultiplier × 12. The base rate per $1,000 of coverage rises with age because mortality risk increases over time. A longer term also costs more because the insurer is on the hook for a greater window of risk. Health rating and smoking status are multipliers — poor health or smoking can roughly double or triple premiums. This model provides a useful ballpark, though actual quotes vary by insurer and underwriting criteria.
How to use
Suppose you are 35 years old, want $500,000 of coverage for 20 years, have a standard health rating (1.0), and are a non-smoker (1.0). Step 1: Base rate = 500,000 / 1,000 = 500. Step 2: Age factor = 0.5 + (35 − 20) × 0.08 = 0.5 + 1.2 = 1.7. Step 3: Term factor = 1 + (20 − 10) × 0.02 = 1.2. Step 4: Annual premium = 500 × 1.7 × 1.2 × 1.0 × 1.0 × 12 = $12,240 per year. Adjust inputs to see how smoking or a longer term affects your estimated cost.
Frequently asked questions
How does age affect term life insurance premium costs?
Age is the single biggest driver of term life insurance premiums because older applicants have statistically higher mortality risk. In this model, each additional year of age beyond 20 adds 0.08 to the base rate multiplier, compounding cost noticeably after age 40. A 25-year-old will pay significantly less than a 45-year-old for identical coverage. This is why financial advisors consistently recommend locking in a policy while you are young and healthy.
Why do smokers pay more for term life insurance than non-smokers?
Smoking is directly linked to higher rates of cancer, heart disease, and respiratory illness, all of which increase mortality risk for insurers. Most life insurers charge smokers 2–4 times the non-smoker rate for the same coverage. Even if you quit smoking, many insurers require 1–5 years of abstinence before reclassifying you as a non-smoker for underwriting purposes. Using this calculator with a smoker multiplier reflects that real-world pricing gap.
What term length should I choose when buying term life insurance?
The right term length depends on the financial obligations you want to protect against. Common choices are 10, 20, or 30 years, aligned with milestones like paying off a mortgage, raising children to adulthood, or reaching retirement. A longer term gives more protection but costs more because the insurer's exposure window is wider. Many financial planners recommend matching your term length to the years until your youngest dependent becomes financially independent.
