The Triple Paycheck Month: Beancount Queries That Find Your 2026 Bonus Paychecks

If you are paid biweekly, twice a year you will get three paychecks in a month instead of two. For 2026, the bonus months are either January and July (if the first paycheck was paid on Jan. 2), or May and October (if the first paycheck was paid on Jan. 9).

These extra paychecks are a powerful savings opportunity because your fixed monthly expenses are already covered by the first two.

Finding Your Triple Paycheck Months

First, figure out your pay schedule:

; My biweekly pay dates in 2026
; First paycheck: January 9
; Pattern: every other Friday

; The math: 52 weeks / 2 = 26 paychecks
; But some months have 5 Fridays

Tracking Paychecks by Month

I tag each paycheck with a month indicator:

2026-01-09 * "Employer" "Paycheck 1" #paycheck-2026
  Assets:Bank:Checking     4500 USD
  Income:Salary:Gross     -6000 USD
  Expenses:Tax:Federal     1000 USD
  Expenses:Tax:State        300 USD
  Expenses:Tax:FICA         200 USD
    paycheck_number: "1"
    month: "January"
    
2026-01-23 * "Employer" "Paycheck 2" #paycheck-2026
  ; Same structure...

The Query That Finds Triple Months

SELECT 
  MONTH(date) as month,
  COUNT(*) as paychecks
WHERE 
  #paycheck-2026
  AND account = "Assets:Bank:Checking"
GROUP BY month
HAVING COUNT(*) > 2

Output shows May and October with 3 paychecks each.

What to Do With the Extra Paycheck

Since your budget is built around 2 paychecks per month, the third one is surplus:

Option 1: Boost retirement savings

2026-05-29 * "Employer" "Paycheck 3 - bonus month"
  Assets:Bank:Checking     4500 USD
  Income:Salary:Gross     -6000 USD
  ; ... taxes ...

2026-05-30 * "Transfer" "Extra paycheck to 401k catch-up"
  Assets:Retirement:401k:Traditional  4500 USD
  Assets:Bank:Checking               -4500 USD

Option 2: Build emergency fund

2026-05-30 * "Transfer" "May bonus paycheck to emergency"
  Assets:Savings:Emergency   4500 USD
  Assets:Bank:Checking      -4500 USD

Option 3: Pay down debt

2026-05-30 * "Extra payment" "Student loan principal"
  Liabilities:StudentLoan:Federal   4500 USD
  Assets:Bank:Checking             -4500 USD
    principal_only: TRUE

Annual Impact

Two extra paychecks at $4,500 net = $9,000 annual savings opportunity

If invested at 7% over 20 years: approximately $360,000 in additional wealth.

Weekly Pay? Even Better

People paid weekly have five-paycheck months in January, May, July and October in 2026. That is four bonus paychecks to allocate.

Questions
