Example Data Table
| Settlement Date | Maturity Date | Basis | Calendar Days | Business Use |
|---|---|---|---|---|
| 2026-01-15 | 2026-04-15 | Actual/365 | 91 | Short note or bill |

Formula Used
Calendar days: Maturity Date - Settlement Date
Business days: Count weekdays between settlement and maturity. Remove listed holidays.
Actual/360: Year Fraction = Actual Days / 360
Actual/365: Year Fraction = Actual Days / 365
Actual/Actual: Days are divided by each year length. Leap years use 366.
30/360: 360 × Year Difference + 30 × Month Difference + Day Difference
Estimated accrued amount: Principal × Annual Rate × Year Fraction

Days to Maturity Guide
What Days to Maturity Means
Days to maturity shows the remaining time before an instrument reaches its final date. It is common in bonds, treasury bills, certificates, loans, deposits, and private notes. The value helps investors compare timing, risk, yield, and cash flow. A shorter maturity usually gives quicker repayment. A longer maturity usually creates more rate exposure.
Why the Count Matters
A date gap looks simple at first. Yet finance often needs more detail. Calendar days, business days, and day count fractions can give different answers. Each answer has a purpose. Calendar days measure plain elapsed time. Business days help with settlement planning. Year fractions support interest and accrual calculations.
Settlement and Maturity Dates
The settlement date is the starting point. The maturity date is the final point. Many markets exclude the settlement date. They often include the maturity date. This calculator gives an option for that choice. It also shows adjusted maturity dates when a maturity falls on a weekend or holiday.
Business Day Adjustments
Real payments rarely settle on closed market days. A following rule moves the date forward. A preceding rule moves it backward. A modified following rule first moves forward. If the new date enters another month, it moves backward. This rule is useful for many financial schedules.
Day Count Basis
Day count basis changes the year fraction. Actual/360 is common in money markets. Actual/365 is useful for simple annual estimates. Actual/Actual handles leap years with more care. The 30/360 methods treat months as thirty days. That makes fixed income comparisons easier across periods.
Interest Estimate
The calculator also estimates accrued amount. It multiplies principal by annual rate and year fraction. This is not a full bond pricing model. It is a practical estimate for timing and accrual review. For precise trading, confirm the contract terms and market convention.
Calendar Days Versus Business Days
Calendar days include weekends. Business days remove Saturdays and Sundays. They can also remove custom holidays. This is important for banks, brokers, and treasury teams. A payment may mature on a Sunday. The payable date may move to Monday or an earlier Friday.
Using the Results
Use the results to plan cash receipts, compare instruments, and schedule reminders. Export the table when you need a record. The CSV file works well in spreadsheets. The PDF file is helpful for reports, client notes, and approvals. Always review the selected convention before sharing results.
Accuracy Tips
Enter dates in the correct format. Add known market holidays. Select the same day count basis used by the agreement. Check whether the maturity date should be included. These small details can change the final number. They can also change the interest estimate.
Best Use Cases
This tool is helpful for short term bills, fixed deposits, private lending, project payments, and bond timing. It can also support education and audit checks. It keeps the work clear. It also gives fast exports for later review.
Frequently Asked Questions
1. What is days to maturity?
Days to maturity is the number of days between a starting date and the final maturity date. It helps measure remaining time for bonds, loans, bills, deposits, and other dated financial instruments.
2. What is the settlement date?
The settlement date is the date from which the maturity count starts. In finance, this is often the purchase date, issue date, trade settlement date, or loan start date.
3. Should I include the maturity date?
Many calculations exclude the start date and include the maturity date. Some internal reports may not. Use the checkbox to match your agreement, market rule, or reporting method.
4. What are calendar days?
Calendar days count every day in the date range. They include weekdays, weekends, and holidays. This is useful for plain elapsed time and simple planning.
5. What are business days?
Business days usually exclude Saturdays and Sundays. This calculator also removes custom holiday dates that you enter. It is useful for banking and settlement planning.
6. What is Actual/360?
Actual/360 divides actual calendar days by 360. It is common in money markets and short term interest calculations. It can produce a larger fraction than Actual/365.
7. What is Actual/365?
Actual/365 divides actual calendar days by 365. It is simple and useful for annual estimates. It does not adjust the denominator to 366 in leap years.
8. What is Actual/Actual?
Actual/Actual uses actual days and the true year length. Leap year segments use 366 days. Non-leap year segments use 365 days.
9. What does 30/360 mean?
30/360 treats each month as thirty days and each year as 360 days. It is often used for bond style comparisons and structured schedules.
10. What is modified following?
Modified following moves a non-business maturity date forward first. If that move changes the month, it moves the date backward instead.
11. Can I add market holidays?
Yes. Enter each holiday date on a new line. The business day result will exclude those dates along with Saturdays and Sundays.
12. Does this calculate bond price?
No. It calculates timing, year fraction, and a simple accrued amount estimate. Full bond pricing needs coupon dates, yield, clean price, and market convention.
13. Why is business day count different?
Business day count removes weekends and entered holidays. Calendar day count does not. That is why the two values often differ.
14. Can I export the result?
Yes. Use the CSV button for spreadsheet work. Use the PDF button for a simple printable report.
