The Future Value of Annuity Calculator is a powerful financial tool that determines the total accumulated value of a series of regular payments at a specified point in the future. Whether payments are made monthly, quarterly, yearly, or at any other interval, this calculator provides an accurate estimate based on interest rate and time duration.
It helps you calculate annuity payments, interest growth, and total accumulation efficiently. To understand how the calculator works, it is essential to first understand what an annuity is and how it functions.
An annuity is a series of equal payments made at consistent time intervals. These payments can occur weekly, monthly, quarterly, or annually. Common real-life examples include retirement pensions, loan repayments, insurance premiums, and regular savings contributions.
The Future Value of Annuity Calculator estimates how much these repeated payments will grow over time, depending on the selected payment frequency and interest rate.
Annuities are generally classified into two main types:
An ordinary annuity consists of payments made at the end of each period. This is the most common form of annuity in loans and mortgages.
The formula for calculating the future value of an ordinary annuity is:
FV = C × [((1 + i)n − 1) / i]
Where:
Suppose you deposit $1,000 annually for 5 years at an interest rate of 5%.
C = 1000
i = 0.05
n = 5
FV = 1000 × [((1.05)5 − 1) / 0.05]
FV ≈ 1000 × 5.5256
FV ≈ $5,525.64
This means the total accumulated value after 5 years is $5,525.64.
An annuity due involves payments made at the beginning of each period. Because each payment earns interest for one additional period, its future value is slightly higher than an ordinary annuity.
The formula for annuity due is:
FV = C × [((1 + i)n − 1) / i] × (1 + i)
Using the same example:
FV = 1000 × 5.5256 × 1.05
FV ≈ $5,801.91
This higher value occurs because payments are invested earlier.
The total number of payment intervals over the investment duration.
The growth rate applied per period. The calculator converts percentages into decimal form automatically.
The fixed amount paid each period.
An optional rate if payments increase over time (used in growing annuities).
The number of payments made per year (e.g., 12 for monthly, 4 for quarterly, 1 for annual).
The total accumulated value of all payments at the end of the annuity term.
The table below shows the future value factors for $1 paid per period, with interest rates ranging from 1% to 5% and periods from 1 to 40. These values apply specifically to an ordinary annuity.
You can multiply these factors by your actual payment amount to determine the total future value.

Output:
Mortgage payments are a common example, where payments are made at the end of each month.
Rent payments and insurance premiums are typically paid at the beginning of each period, making them annuity due examples.
Yes. In most cases, annuity payments are considered taxable income depending on the portion that represents earnings.
Immediate annuities are often preferred by retirees because they begin generating income shortly after purchase.
Annuities provide a structured and reliable way to build savings or generate income over time. Understanding the difference between ordinary annuity and annuity due is crucial for accurate financial planning. The Future Value of Annuity Calculator simplifies these complex calculations, allowing you to make informed investment decisions with ease.
