In order to figure out how much insurance you need, you will need to explore your current household expenses, debts, assets, and streams of income. If you need assistance in this, consult either your accountant or financial advisor.
The amount of money that you want to leave behind for your dependents should allow them to use some of the money to maintain their current standard of living, then reinvest another lump sum to ensure that they will be well off in the future.
When attempting to calculate the amount of money that you need to leave behind, be extremely meticulous. If you err low, your family may not receive the help that they need from the insurance company, and if you err the other way, you will be spending more than necessary in insurance premiums.
