2.25 APY Savings Account Calculator

This calculator helps you determine how much interest you'll earn with a 2.25% Annual Percentage Yield (APY) savings account. APY represents the actual annual rate of return after accounting for compounding interest, which can significantly increase your earnings over time.

How a 2.25% APY Savings Account Works

A 2.25% APY savings account means your money grows by 2.25% each year, compounded based on the account's terms. Most savings accounts compound interest daily, which means your balance grows slightly each day, leading to a higher effective yield than simple annual interest.

Key Concepts

APY: The actual annual rate of return after compounding interest.
APR: The stated annual interest rate before compounding.
Compounding: The process of earning interest on both your initial deposit and previously earned interest.

How Compounding Works

With daily compounding, your balance grows as follows:

You deposit $1,000 at the start of the year.
Each day, your balance increases by 2.25%/365 of the previous day's balance.
By the end of the year, your balance has grown to more than $1,022.50.

The difference between APY and APR becomes more significant with higher interest rates and longer time periods. For example, a 2.25% APY account with daily compounding is equivalent to approximately a 2.30% APR.

Example Calculations

Let's look at how different deposit amounts and time periods affect your earnings with a 2.25% APY savings account.

Example 1: $1,000 Deposit for 1 Year

With a $1,000 deposit and 2.25% APY with daily compounding:

Starting balance: $1,000
Daily interest rate: 2.25%/365 ≈ 0.006164%
Ending balance: $1,022.50
Interest earned: $22.50

Example 2: $5,000 Deposit for 5 Years

With a $5,000 deposit and 2.25% APY with daily compounding:

Starting balance: $5,000
Daily interest rate: 2.25%/365 ≈ 0.006164%
Ending balance: $5,535.84
Interest earned: $535.84

Deposit Amount	Time Period	Interest Earned	Ending Balance
$1,000	1 year	$22.50	$1,022.50
$5,000	1 year	$112.50	$5,112.50
$1,000	5 years	$535.84	$5,535.84
$5,000	5 years	$2,679.23	$7,679.23

APY vs. APR

The key difference between APY and APR is how they account for compounding interest. APR is the stated annual interest rate, while APY reflects the actual annual rate of return after compounding.

APY Formula

APY can be calculated using the following formula for daily compounding:

APY Formula

APY = (1 + (APR / n))^n - 1

Where:

APR = Annual Percentage Rate
n = Number of compounding periods per year

For a 2.25% APY account with daily compounding, the equivalent APR is approximately 2.30%. This means you're effectively earning slightly more than the stated rate due to compounding.

Frequently Asked Questions
