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
custom 2026-01-01 "payroll" "2026 triple months: May, October"
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.
