Coverage amount is the single lever that changes your premium the most dramatically — far more than most people expect. This guide breaks down exactly how price scales as coverage goes up, so you can see where the real value sits before locking in a number.
Quick answer: Life insurance premiums increase with coverage amount, but not in a straight line — a portion of every policy’s cost covers fixed administrative overhead, so higher coverage tiers cost less per dollar of protection than lower ones. For a healthy 40-year-old man on a 20-year term, $100,000 in coverage runs around $19/month, while $1,000,000 runs about $109/month — less than 6x the price for 10x the coverage.
Full Coverage Amount Cost Table (Age 40, Male, 20-Year Term)
| Coverage Amount | Monthly Premium | Cost per $100,000 of Coverage |
|---|---|---|
| $100,000 | ~$19 | $19.00 |
| $250,000 | ~$35 | $14.00 |
| $500,000 | ~$59 | $11.80 |
| $750,000 | ~$85 | $11.33 |
| $1,000,000 | ~$109 | $10.90 |
| $2,000,000 | ~$216 | $10.80 |
| $3,000,000 | ~$315 | $10.50 |
| $5,000,000 | ~$504 | $10.08 |
| $10,000,000 | ~$980 | $9.80 |
Illustrative sample rates for a healthy nonsmoking 40-year-old male based on 2026 market averages. Women typically pay roughly 15-25% less at every tier for the same profile — see our guide on life insurance cost by age for gender-specific figures at $500,000 and $1,000,000. Actual quotes vary by insurer and health class.
Why More Coverage Gets Cheaper Per Dollar
This is the pattern worth understanding before you shop: as you move up the table, the «cost per $100,000 of coverage» column steadily drops — from $19.00 at the smallest tier down to $9.80 at the largest. That’s because every policy, regardless of size, carries a similar underlying administrative cost to the insurer (processing, underwriting, servicing). At small coverage amounts, that fixed cost makes up a larger share of your premium. At large amounts, it’s diluted across a much bigger death benefit — so the marginal dollar of coverage gets cheaper the more you buy.
The practical takeaway: if you’re debating between two coverage amounts that are relatively close together (say, $500,000 vs. $750,000), the price difference is often smaller than people assume — worth erring toward the higher amount if your DIME calculation supports it, rather than trimming coverage to save what turns out to be a modest amount per month.
Where the Curve Changes: Small vs. Large Policies
Under $500,000: cost scales fastest here
This is where you’ll see the steepest cost-per-dollar drop as you increase coverage — going from $100,000 to $250,000 nearly doubles your protection while increasing your premium by less than double. If your calculated need lands in this range, it’s worth double-checking you haven’t underbought simply to hit a lower round number.
$500,000 to $2,000,000: the most common range
Most working adults with dependents and a mortgage land somewhere in this range once they run the DIME method. Cost-per-dollar continues to improve gradually, but the differences are smaller than in the lower tiers.
Above $2,000,000: financial underwriting enters the picture
Beyond roughly $1-2 million, insurers typically require documentation justifying the amount relative to your income and net worth (see our full guide on $1 million life insurance cost for how this financial underwriting works). The per-dollar cost keeps improving slightly, but qualifying — not price — becomes the bigger consideration at this level.
How to Use This Table to Estimate Your Own Price
- Calculate your actual coverage need first, using the DIME method in our guide on how much life insurance you need — don’t start from a price and work backward.
- Find the closest coverage tier in the table above to see a rough monthly cost at age 40.
- Adjust for your own age using our age-based rate tables, since age affects the base rate independently of coverage amount.
- Adjust for gender and health, which shift the number up or down from this baseline — see our guides on what determines your premium and life insurance by health condition.
- Get an actual quote to replace these estimates with your real, underwritten number — the table above is a planning tool, not a substitute for a personalized quote.
A Common Mistake: Underbuying to Hit a «Safe» Number
Because the cost-per-dollar improves at higher tiers, rounding down to a smaller, «safer-sounding» coverage amount often saves less money than people expect, while leaving a real protection gap. For example, moving from $750,000 to $1,000,000 in the table above adds roughly $24/month — a relatively small increase for $250,000 in additional protection. If your DIME calculation points to needing closer to $1,000,000, trimming to $750,000 to save $24/month may not be the trade-off it appears to be.
Does This Pricing Pattern Hold for Whole Life Insurance Too?
Not in the same way. Whole life insurance’s cash-value component makes its pricing structure fundamentally different — coverage amount still affects price, but the relationship isn’t driven by the same fixed-cost dilution effect, since a much larger portion of a whole life premium goes toward building cash value rather than covering pure mortality risk. See our guide on term life vs whole life insurance for the full comparison.
Frequently Asked Questions
Why did doubling my coverage amount not double my quote?
This is expected — a portion of every policy’s premium covers fixed costs that don’t scale directly with coverage amount, so larger policies cost less per dollar of protection than smaller ones.
Is there a coverage amount where price stops mattering?
Not exactly, but the rate of improvement slows down significantly above a few million dollars — at that point, qualifying through financial underwriting becomes a bigger factor than the marginal price difference.
Should I just buy the largest amount I can afford, since it’s cheaper per dollar?
Not necessarily — buy based on your calculated need (see our DIME method guide), not purely because the per-dollar price looks better at higher tiers. Overbuying still means paying more in absolute terms than you need to.
Do these same tiers and pricing patterns apply to no-medical-exam policies?
The same general pattern holds, but no-exam policies are priced somewhat higher across the board and often cap out around $1-2 million — see our guide on no-medical-exam life insurance for specifics.
Bottom Line
Coverage amount is the biggest lever in your life insurance price, but it doesn’t scale in a straight line — every additional dollar of coverage gets slightly cheaper as you move up the table. Use this pattern to your advantage: calculate your real need first, then check where it falls on the curve, rather than picking a smaller round number just because it sounds more conservative.
