What Is an Annuity?
An annuity is a financial concept where you make regular payments over a specific period of time. These payments can be weekly, monthly, quarterly, or annually, and they grow over time due to interest.
Common examples of annuities include:
- Retirement savings plans
- Pension contributions
- Investment funds with regular deposits
- Loan repayments (in reverse calculation scenarios)
Understanding annuities helps you see the long-term impact of consistent saving and compound interest.
