The most common question people ask about life insurance isn't "do I need it?" (if you have dependents, you do), but "how much should I get?"
Pick a number that's too low, and your family could struggle to pay the bills a few years after you're gone. Pick a number that's too high, and you're wasting money on monthly premiums that could be invested elsewhere. Finding the "Goldilocks" number requires a bit of math, but it's simpler than you think. Here are three methods to calculate your coverage need.
Method 1: The "10x Income" Rule (The Quickest)
This is the standard rule of thumb recommended by many financial advisors for a quick estimate. Calculation: Take your annual gross income and multiply it by 10.
- Example: You earn $75,000/year. You need $750,000 in coverage.
Pros: Fast and easy. Cons: It ignores your specific debts and assets. If you have 5 kids and a huge mortgage, 10x might not be enough. If you are single with no debt, it might be too much.
Method 2: The DIME Method (The Detailed)
This method breaks down your financial obligations into four categories: Debt, Income, Mortgage, Education.
- Debt: Add up all your non-mortgage debts (credit cards, student loans, car loans) that you want paid off.
- Income: Multiply your annual income by the number of years your family would need support (e.g., until the youngest child turns 18 or 22).
- Mortgage: Enter your remaining mortgage balance.
- Education: Estimate the cost of college for your children. (Current average for 4-year in-state public college is ~$100,000 per child).
Calculation: Debt + Income Replacement + Mortgage + Education = Total Need.
- Example:
- Debt: $15,000
- Income: $75,000 x 15 years = $1,125,000
- Mortgage: $250,000
- Education: $100,000 (1 child)
- Total Need: $1,490,000
Method 3: The "Capital Retention" Approach (The Legacy)
This method aims to provide a permanent stream of income without ever touching the principal payout. Your family lives off the interest generated by the insurance money. Calculation: Divide your desired annual income replacement by a conservative investment rate of return (like 4% or 5%).
- Example: You want to provide $75,000/year.
- $75,000 / 0.05 (5% return) = $1,500,000.
Pros: The money lasts forever and can be passed down to the next generation. Cons: Requires a much larger policy, which means higher premiums.
Don't Forget to Subtract Assets
If you already have savings, you don't need to insure that amount.
- Formula: (Financial Obligations) - (Savings + Retirement Accounts + Existing Life Insurance) = Net Insurance Gap.
Inflation is Real
Remember that $500,000 today won't buy as much in 20 years. It's smart to add a "cushion" of 10-15% to your final number to account for inflation, especially if you are buying a long-term policy.
