Average Monthly Account Balance Calculator

Reviewed by Calculator Editorial Team

Tracking your average monthly account balance helps you understand your financial position over time. This calculator provides a simple way to compute your average balance based on your monthly deposits and withdrawals.

What is Average Monthly Account Balance?

The average monthly account balance is a financial metric that represents the typical amount of money in your account over a 30-day period. It's calculated by summing all deposits and subtracting all withdrawals, then dividing by the number of days in the period.

This measurement is important for:

  • Understanding your spending patterns
  • Assessing your financial health
  • Qualifying for loans or credit cards
  • Tracking savings progress

How to Calculate Average Monthly Account Balance

To calculate your average monthly account balance, you'll need:

  1. Your starting balance at the beginning of the month
  2. All deposits made during the month
  3. All withdrawals made during the month
  4. The number of days in the month (usually 30 for calculation purposes)

The calculation process involves:

  1. Summing all deposits
  2. Summing all withdrawals
  3. Calculating the net change (deposits - withdrawals)
  4. Dividing the net change by the number of days

The Formula

Average Monthly Account Balance Formula

Average Balance = (Starting Balance + Total Deposits - Total Withdrawals) / Number of Days

Where:

  • Starting Balance = Account balance at month start
  • Total Deposits = Sum of all money added
  • Total Withdrawals = Sum of all money removed
  • Number of Days = Typically 30 for calculation

Worked Example

Let's calculate the average monthly balance for an account with:

  • Starting balance: $1,000
  • Total deposits: $1,500
  • Total withdrawals: $800
  • Number of days: 30

Calculation Steps

1. Net Change = Deposits - Withdrawals = $1,500 - $800 = $700

2. Average Balance = ($1,000 + $700) / 30 = $1,700 / 30 ≈ $56.67

The average monthly account balance in this example is approximately $56.67 per day.

FAQ

Why is the number of days usually 30?

Using 30 days standardizes the calculation across months with different lengths, making it easier to compare balances over time. Most financial institutions use this convention.

How does this differ from average daily balance?

Average daily balance is calculated by dividing the total balance by the number of days in the month. Average monthly account balance uses the net change over the period.

Is this the same as average balance?

No, average balance typically refers to the average of daily ending balances. This calculator provides the average based on net changes.
