What Is a Guaranteed Income Annuity?

A Guaranteed Income Annuity (GIA) is a financial product that converts a lump-sum investment into regular income payments over a specified period.

Instead of receiving your money all at once, the investment is structured to provide payments such as:

• Monthly
• Quarterly
• Semi-annually
• Annually

The income payments depend on several factors:

• Initial investment (principal)
• Interest rate
• Duration of the payout
• Payment frequency

A Guaranteed Income Annuity Calculator simplifies the process by calculating your expected payments instantly.
