Present Value (PV) Annuity Calculator

What is a Present Value (PV) Annuity Calculator?

A Present Value (PV) Annuity Calculator is a financial tool that helps you determine the current worth of a series of future annuity payments. This calculation is essential for understanding the value of your annuity in today's terms, given a specified interest rate.

Formula for Present Value Annuity Calculation

The formula for calculating the present value of an annuity is:

\[PV = PMT \times \frac{1 - (1 + r)^{-n}}{r}\]

Where:

• PV = Present Value
• PMT = Payment Amount
• r = Monthly Interest Rate (Annual Rate / 12)
• n = Total Number of Payments (Term in Years × 12)

Calculation Steps

1. Calculate the monthly interest rate by dividing the annual rate by 12.
2. Determine the total number of payments by multiplying the term in years by 12.
3. Apply the formula to calculate the present value.
4. Calculate the total interest paid by multiplying the payment amount by the number of payments and subtracting the present value.

Example

Let's consider a scenario with the following details:

• Payment Amount: $1,000
• Interest Rate: 5% per year
• Term: 10 years

Calculation:

1. Monthly interest rate: 5% / 12 = 0.4167%
2. Number of payments: 10 × 12 = 120
3. Present value: $93,451.23
4. Total interest paid: $26,548.77

In this example, the present value of the annuity is $93,451.23. Over the 10-year term, the total interest paid would be $26,548.77. This calculation helps you understand the current worth of your future annuity payments.
