Life insurance exists to replace income and cover obligations if you die while others depend on you. The right amount is a calculation, not a guess.
The DIME method
Add Debt (excluding mortgage), Income (annual income times years to replace), Mortgage balance and Education costs for children. Subtract existing coverage and savings to find the gap. Add final expenses of about $10,000–$20,000.
Rules of thumb
Common shortcuts suggest 10 to 12 times annual income. They are crude; a 30-year-old with young children and a large mortgage may need more, while a retiree with grown kids and no debt may need none.
Who may not need it
Single people without dependents, people with enough assets to cover obligations and retirees with sufficient income often can skip coverage. Stay-at-home parents do need coverage because replacing their work is costly.
Try the numbers
Use our Life Insurance Needs Calculator to see this in practice. With its default example (Annual income to replace: $85,000; Years to replace income: 12; Non-mortgage debts: $18,000), it shows additional coverage needed: $1,223,000. Adjust the inputs to match your situation.
Key takeaways
- Use DIME to size coverage to real obligations.
- Rules of thumb are only rough guides.
- Stay-at-home parents often need coverage too.
