Income Multiplier Life Insurance Calculator
Pick a multiple: 5x, 7x, 10x, 12x, or 15x annual income
Last updated: June 2026
Inputs
10x is the classic rule of thumb. 12-15x for high-need young families.
Multiplier Comparison
Worked Examples
5-7x = $375k - $525k of 20-year term covers debt payoff, final expenses, and a modest buffer. Premium for a healthy 30-year-old: roughly $20-$30/month.
10-12x = $1M - $1.2M of 25- or 30-year term. Covers a $300-400k mortgage, ~15 years of income replacement, and college funding. Premium for a healthy 35-year-old: roughly $35-$55/month.
12-15x = $3M - $3.75M, often split across two laddered policies (20- and 30-year terms) so coverage steps down as obligations end. Premium for a healthy 38-year-old: roughly $150-$250/month.
3-5x = $450k - $750k of 10- or 15-year term, focused on final expenses, residual income for the surviving spouse, and any remaining one-time obligations. Premium varies sharply with age and health.
Use this as a sanity check, not a final answer
Income multiplier is fast and easy, but it ignores your specific debt, mortgage, dependents, and time to retirement. Run the DIME or HLV method too, the right answer is usually the middle of the three.
Frequently Asked Questions
Where does the "10x income" rule come from?
It dates back to a 1960s industry rule of thumb. The logic: 10x income invested at 5% in safe instruments throws off the equivalent of the deceased's pre-tax income in perpetuity, so the family never depletes principal. The math works out roughly: $1M at 5% = $50k/year, replacing a $50k earner. It is simple, easy to sell, and ignores debt, dependents, and the spouse's earnings, which is why financial planners prefer DIME or HLV for serious analysis.
Should I use 5x, 7x, 10x, 12x, or 15x?
A rough guide: 5-7x for single adults with no kids or large debts, 10x as a default for the typical breadwinner with a young family, 12-15x for high earners with multiple young dependents and significant debt. The multiplier should rise with the number of years your family would need replacement and with the size of fixed obligations like a mortgage and education.
Worked example: 35-year-old earning $100k with two kids.
At 10x, that is $1M of term coverage. Invested at 5% it generates $50k/year, replacing roughly half pre-tax income indefinitely. The spouse covers the other half through their own work. At 12x ($1.2M), you add a buffer for inflation and one-time costs like education. A 20-year term policy at this profile in good health typically costs $30-$50/month.
Worked example: 50-year-old earning $200k with grown kids.
At 5x ($1M) the math is different, the focus shifts from income replacement to mortgage payoff, final expenses, and any remaining education or care obligations. With grown kids and a low-balance mortgage, 5x is often plenty. A 15- or 20-year term policy at this age and income costs $200-$400/month depending on health.
Does income multiplier coverage include or exclude debt?
It includes debt by accident, not by design. The multiplier is supposed to be a one-number answer that wraps everything in. If you have unusually large debt (more than ~3x income), bump the multiplier up by 1-2 or use DIME instead. If you have minimal debt and a large existing portfolio, you can usually drop the multiplier by 1-2.
