If you have anyone who relies on you for financial support, you probably need some life insurance to protect them in case you are no longer there to provide for their financial security.
Many people choose to purchase life insurance to replace their income for their loved ones.
When buying a life insurance policy you select a beneficiary or beneficiaries to receive the benefits from your policy upon your passing.
Your beneficiary can use the proceeds they receive for any purpose they wish.
Life insurance benefits can help to replace your income, pay off a mortgage loan, pay for your child's education, pay off debt, provide for your spouse or partner's retirement, provide for living expenses of your family, etc.
The reason you want to buy life insurance as soon as you have a need, is because rates on life insurance are lower for younger healthier people. So, you pay less per year for your life insurance coverage if you buy a policy when you are young and healthy.
