How the Loan / Mortgage Payment Projector works
The Loan / Mortgage Payment Projector takes a start date, a number of payment cycles, and the interval between them in days, and returns the actual due date for every installment — each one rolled to the nearest earlier business day whenever the raw interval date falls on a weekend or a public holiday for the countries you select.
A fixed-day interval is not the same as "the same day every calendar month." Thirty days after January 31 is March 2, not the end of February, and that drift compounds across a payment schedule until the due dates no longer land on a consistent day of the month. If your loan or installment plan is defined by an interval rather than a fixed calendar date, the projected schedule will look different from a naive "same day each month" assumption — and the projection, not the assumption, is what a servicer will actually enforce.
This tool projects payment dates only. It does not calculate interest, amortization amounts, or remaining principal — confirm those figures against your loan agreement or servicer statement.
Worked example
A 12-cycle schedule starting January 31 with a 30-day interval produces due dates that drift across the month — March 2, April 1, May 1 — rather than landing on the 31st (or the nearest equivalent) every time. Any cycle whose raw date falls on a weekend or holiday rolls back to the prior business day, shifting that one installment a day or two earlier than the raw interval math alone would suggest.
Frequently asked questions
Does this calculate my interest or amortization amount?
No. It projects the due <em>dates</em> for each installment from a start date and interval — not the payment amount, interest, or remaining balance. Get those figures from your loan agreement or servicer.
Why don’t my due dates land on the same day every month?
Because the schedule is built from a fixed number of days between payments, not a fixed day of the calendar month. A 30-day interval drifts against months that are 28, 29, or 31 days long, so the day-of-month shifts gradually across the schedule.
Which direction does a weekend or holiday due date move?
This tool rolls back to the nearest earlier business day. Some loan documents instead roll forward to the next business day, effectively granting a short grace period — check your agreement for which convention actually governs.
