Tsp Monthly Withdrawal Calculator

Introduction

Calculating the monthly withdrawal amount is crucial for financial planning, especially when dealing with investments. The TSP Monthly Withdrawal Calculator provides a convenient way to determine the precise amount you can withdraw from your Thrift Savings Plan (TSP) on a monthly basis. This article guides you through using the calculator effectively and explains the underlying formula.

How to Use

Using the TSP Monthly Withdrawal Calculator is straightforward. Simply enter the required information in the designated input fields, click the “Calculate” button, and obtain the accurate monthly withdrawal amount.

Formula

The formula used in this calculator is based on the annuity payment formula:

$PMT = ( 1 + r ) ^{n} - 1 P * r * ( 1 + r ) ^{n}$

Where:

$PMT$ is the monthly payment or withdrawal amount,
$P$ is the principal amount (TSP balance),
$r$ is the monthly interest rate (annual interest rate divided by 12 and converted to a decimal),
$n$ is the total number of payments or months.

Example

Consider an individual with a TSP balance of $100,000, an annual interest rate of 5%, and a withdrawal period of 20 years. Plugging these values into the formula:

$PMT = \frac{100,000 * 0.004167 * (1 + 0.004167)^{240}}{(1 + 0.004167)^{240} – 1} \approx $716.60$

The monthly withdrawal amount, in this case, would be approximately $716.60.
