Formula and assumptions

The 2-5-n-30 rule is based on the following formulas:

Checking Account Minimum

Checking Account Minimum = 2 × Daily Expenses

Savings Account Minimum

Savings Account Minimum = 5 × Daily Expenses

Paycheck Coverage Minimum

Paycheck Coverage Minimum = Days Until Paycheck × Daily Expenses

The calculator assumes that your daily expenses are constant and that you will receive your next paycheck on the specified date. It also assumes that you will not have any additional income or expenses between now and your next paycheck.

Worked examples

Let's look at two examples to illustrate how the 2-5-n-30 rule works.

Example 1: Daily expenses of $50, paycheck in 10 days

If your daily expenses are $50 and your next paycheck is in 10 days:

Checking account minimum: 2 × $50 = $100
Savings account minimum: 5 × $50 = $250
Paycheck coverage minimum: 10 × $50 = $500

You should have at least $100 in your checking account, $250 in your savings account, and $500 in total to cover your expenses until your next paycheck.

Example 2: Daily expenses of $100, paycheck in 5 days

If your daily expenses are $100 and your next paycheck is in 5 days:

Checking account minimum: 2 × $100 = $200
Savings account minimum: 5 × $100 = $500
Paycheck coverage minimum: 5 × $100 = $500

You should have at least $200 in your checking account, $500 in your savings account, and $500 in total to cover your expenses until your next paycheck.

Scenario	Daily Expenses	Days Until Paycheck	Checking Minimum	Savings Minimum	Total Minimum
Example 1	$50	10	$100	$250	$500
Example 2	$100	5	$200	$500	$500
