Factors That Affect Your Annuity Results

Frequently Asked Questions
Common questions about annuity calculations and investment planning
What is an annuity?
An annuity is a financial product that provides a series of payments made at equal intervals. It can be used for retirement planning, where you make regular contributions that grow over time and provide future income.
What's the difference between ordinary and annuity due?
An ordinary annuity makes payments at the end of each period (most common), while an annuity due makes payments at the beginning of each period. Annuity due typically results in higher future value due to compound interest.
How often should I compound interest?
More frequent compounding results in higher returns. Monthly compounding is most common for regular investment accounts, while daily compounding is typical for savings accounts. Choose based on your actual investment vehicle.
What payment frequency should I choose?
Match your payment frequency to your cash flow. Monthly payments are most common and provide good compounding benefits. Quarterly or annual payments may be suitable for larger, less frequent contributions.
How accurate are these calculations?
Very accurate for standard compound interest calculations. Actual results may vary based on actual interest rates, fees, and market conditions. Always consult with a financial advisor for personalized advice.
What's the difference between future value and present value?
Future value calculates how much your current investments will be worth later. Present value calculates how much you need to invest today to reach a future goal. This calculator focuses on future value of regular contributions.
Should I include inflation in my calculations?
For long-term planning, consider inflation's impact on purchasing power. A 3% annual inflation rate reduces the real value of future money by about 26% over 10 years. Use our inflation calculator for detailed analysis.
How do taxes affect annuity calculations?
Taxes can significantly impact returns. Traditional retirement accounts defer taxes until withdrawal, while Roth accounts provide tax-free growth. Consider your tax situation when planning contributions.
