Income replacement is the biggest single component of most life insurance calculations, but “how many years” is where people guess instead of calculate. Here’s how to actually land on the right number.
The Standard Range: 10 to 20 Years
Most financial advisors recommend replacing 10 to 20 years of income, depending on your family’s timeline. The idea is simple: give your dependents enough time to adjust, finish raising kids, or reach a point (like retirement or a paid-off mortgage) where they need less support from your income.
What Pushes You Toward More Years
- Young children. If your kids are toddlers, 20 years of replacement covers them through college.
- A non-working or lower-earning spouse who would need significant time to rebuild career income or credentials.
- A long mortgage that won’t be paid off for 20+ years.
What Pushes You Toward Fewer Years
- Older children who are already teenagers or in college.
- Significant existing savings or retirement accounts that could bridge a shorter gap.
- A working spouse with strong, stable income of their own.
How to Calculate It
Multiply your annual take-home income by your chosen number of years, then adjust: subtract expected Social Security survivor benefits (modest, but real) and any existing savings earmarked for this purpose. This income-replacement figure is one piece of the full DIME calculation — combine it with debt, mortgage, and education costs for your total coverage need.
| Annual Income | 10 Years | 15 Years | 20 Years |
|---|---|---|---|
| $50,000 | $500,000 | $750,000 | $1,000,000 |
| $75,000 | $750,000 | $1,125,000 | $1,500,000 |
| $100,000 | $1,000,000 | $1,500,000 | $2,000,000 |
Frequently Asked Questions
Should I use gross income or take-home pay?
Take-home (after-tax) pay is more accurate, since that’s what your family actually relies on day to day.
What if both spouses work?
Calculate income replacement separately for each spouse, based on what the household would actually lose if that specific person’s income stopped.
The Bottom Line
There’s no universal right answer for how many years of income to replace — it depends on your kids’ ages, your spouse’s earning capacity, and how long your major expenses will last. 15–20 years is a reasonable default for most families with young children.
