An annuity is an insurance product designed to guarantee income. In exchange for a lump sum of money you get a paycheck for a predetermined amount of time.

To get an estimate with this lifetime annuity calculator, enter your: age, sex (used to estimate your life expectancy and how long payments might last), the age when you want income to start, investment amount, and whether or not you want your spouse to continue to get payments after you die.

The calculator will quickly get you different estimates, enabling you to compare payment options and assess the total lifetime value of your investment.

What Kinds of Annuities Are There?

According to investor.gov, there are three kinds of annunities: fixed (the insurance company promises you a minimum rate of interest and a fixed amount of periodic payments), variable (your payments will vary, depending on investment returns), and indexed (combines features of securities and insurance products).

However, there are actually many different kinds of annuities and a huge variety of riders that can apply to annuities like inflation protection, spousal coverage, return of premium, and more.

Annuity

An annuity is a financial product sold by insurance companies that provides a stream of payments over time to the purchaser (annuitant).

There are a lot of different flavors of annuity contracts and they can be complex. Yet, there are many benefits to the user. Including lifetime income and annual adjustments to your living expense.

Lifetime Annuity

A lifetime annuity is a financial product you can buy with a lump sum of money. In return, you will receive income for the rest of your life.

A lifetime annuity guarantees payment of a predetermined amount for the rest of your life. This is different from a term annuity which only pays you for a fixed amount of time.

Immediate Lifetime Annuity

An immediate annuity provides income to the purchaser that starts as soon as they deposit a lump sum.

The payments last for:

  • The lifetime of the purchaser
  • The lifetime of the purchaser and his or her spouse (or joint annuitant)
  • Some set amount of time (5, 10, 20 years)

This is also referred to as a Single Premium Immediate Annuity (SPIA).

Many people roll over tax qualified funds into a “tax-deferred” immediate annuity. Often the user only pays taxes when they receive the monthly payment (so you pay taxes over time). They only pay taxes on their tax qualified deferred income payment.

This is different from a Deferred Lifetime Annuity where the purchaser pays in over time (or one lump sum). Read more about Deferred Lifetime Annuities in the following section.

Deferred Lifetime Annuity

A Deferred Lifetime Annuity is where the payments start at a predetermined future date. With a Deferred Annuity the purchaser pays in over time (or one lump sum). The money is then invested by the insurance company. It is invested until the stream of payments starts at some point in the future.

A Deferred Annuity is most often used when you think there will be an income need in the future, but not immediately. For example, if you have a job now, but foresee stopping work and still needing the income at a later date. Or, if you think medical or long term care costs will require extra income as you age.

Fixed Annuity

A fixed annuity pays a fixed rate of return. It is typically invested in lower risk fixed income products. For example, government securities and corporate bonds.

Variable Annuity

A variable annuity pays a variable rate of return. Variable annuities invest in riskier assets. For example, mutual funds that hold equities. Variable annuities can provide a higher rate of return, but they have more risk. It is possible for your monthly payment to fall.

Term Annuity

A term annuity is a financial product that guarantees payment for a specific period of time such as 5, 10 or 20 years.

Joint Annuitant

A joint annuitant is typically the spouse of the purchaser of an annuity (the annuitant). Often retirees who want to secure lifetime income will buy a joint annuity. This will secure payments for as long as either the annuitant or joint annuitant is alive.

Survivor Benefit

When people buy Joint & Survivor annuities that make payments for as long as either annuitant is alive. They can elect to change the size of the payment to the surviving annuitant when one of them passes away. The survivor benefit can be 100%, 75%, 66% or 50% of the original payment amount. It depends on what income amount the purchasers think will be necessary at that point in their lives.

Monthly Income

Enter the monthly amount you think you will need from an annuity to cover a gap in your retirement income. The Annuity Calculator will bring back quotes for what it would cost to buy this level of monthly income.

Lump Sum

Enter the savings you have available that you could convert to an annuity. The Annuity Calculator will tell you how much monthly income it would produce for the rest of your life.
