How the ACH Settlement Date Calculator works
The ACH Settlement Date Calculator projects when an ACH file settles by adding the settlement window to the date the file is originated, counting only banking days. Enter the origination date and the number of business days for your ACH speed, choose the relevant bank-holiday calendar, and the tool counts forward, skipping weekends and Federal Reserve holidays.
ACH never settles on weekends or Federal Reserve holidays, so settlement is always measured in banking days, not calendar days. That is why a file originated on a Friday does not advance over the weekend, and why a "two-day" payment can span four calendar days when a holiday falls in the middle. Anchor on the effective origination date — the banking day your file actually clears your bank’s daily cutoff, not the wall-clock day you hit submit.
The right number to enter depends on the speed you are using: 0 business days for same-day ACH, 1 for next-day (T+1) credits common in payroll today, and 2 for the traditional T+2 default still used for many debits. For payroll, run the count in reverse — find the latest origination date whose settlement lands on or before payday.
Worked example
Originate a standard two-day file on Thursday the 10th when the following Monday the 14th is a Federal Reserve holiday: Friday the 11th is day one, the weekend is skipped, Monday is a holiday and is skipped, so settlement is Tuesday the 15th — four calendar days from a "two-day" payment. Switch the same file to next-day ACH and it settles Friday the 11th instead.
Frequently asked questions
Why does ACH skip weekends and holidays?
The ACH network processes on banking days only. Saturdays, Sundays, and Federal Reserve holidays are not settlement days, so the clock pauses over them. Always count banking days, not calendar days, or a payment can land a day or more later than expected.
How many business days should I enter?
It depends on the ACH speed: 0 for same-day ACH, 1 for next-day (T+1) credits, and 2 for the traditional two-day (T+2) default. The same origination date produces a different settlement date for each, so enter the window you actually paid for.
Does the bank cutoff time matter?
Yes. Every originating bank sets a daily cutoff after which a file is treated as submitted the next banking day, which shifts every downstream date. Enter the effective origination date — the banking day your file beats the cutoff — and confirm exact timing with your bank.
