How to Compute Your Semester of Contingency for 2026
If you’re planning to apply for SSS Maternity Benefits in 2026, one of the most confusing but important terms you’ll encounter is the “semester of contingency.”
Many first-time moms get overwhelmed trying to understand how SSS computes this — yet this single detail determines whether your maternity benefit will be approved or denied.
In this guide, we’ll explain in simple, step-by-step terms what the semester of contingency means, how to compute it correctly, and how it affects your qualifying period for maternity benefits.
We’ll also include real stories of Filipina moms and a free tool — the

đź’ˇ What Is the Semester of Contingency?
The semester of contingency refers to the 6-month period (two consecutive quarters) that includes the Expected Delivery Date (EDD) of the member.
It’s the “semester” when the qualifying event — like childbirth, miscarriage, or pregnancy termination — occurs.
For maternity benefits, this semester is excluded when calculating your 12-month qualifying period.
đź§ In short:
Semester of contingency = The quarter of your EDD + the quarter immediately before it.
đź“… Understanding Quarters in SSS
Each year is divided into four quarters, each lasting three months:
| Quarter | Months |
|---|---|
| 1st Quarter (Q1) | January – March |
| 2nd Quarter (Q2) | April – June |
| 3rd Quarter (Q3) | July – September |
| 4th Quarter (Q4) | October – December |
So, when you know your EDD, you can easily determine which two quarters make up your semester of contingency.
đź§® Step-by-Step Guide: How to Compute Your Semester of Contingency
Let’s go through some examples based on 2026 due dates:
🍼 Example 1 – EDD: February 2026
- February 2026 falls in Q1 2026 (Jan–Mar).
- The quarter before that is Q4 2025 (Oct–Dec).
- Therefore, your semester of contingency is Q1 2026 + Q4 2025.
👉 This means your qualifying period will start after September 2025, excluding these quarters.
🍼 Example 2 – EDD: June 2026
- June 2026 falls in Q2 2026 (Apr–Jun).
- The previous quarter is Q1 2026 (Jan–Mar).
- Your semester of contingency is Q2 2026 + Q1 2026.
👉 Your qualifying period will be January 2025 – December 2025.
🍼 Example 3 – EDD: October 2026
- October 2026 is in Q4 2026 (Oct–Dec).
- The previous quarter is Q3 2026 (Jul–Sep).
- Your semester of contingency is Q4 2026 + Q3 2026.
👉 Therefore, your qualifying period will be July 2025 – June 2026.

Rowena’s Story – OFW on Vacation Leave
Rowena, an OFW from Dubai, was due in November 2026. She discovered her semester of contingency was Q4 2026 + Q3 2026, so her qualifying period was July 2025–June 2026. She quickly updated her voluntary payments abroad to complete three contributions — ensuring her eligibility.
Dianne’s Story – Newly Married Teacher
Dianne from Baguio had her EDD in February 2026. After computing, her semester of contingency was Q1 2026 + Q4 2025, making her qualifying period October 2024–September 2025. Her regular government contributions perfectly matched that window, giving her peace of mind.
Leah’s Story – Market Vendor and First-Time Mom
Leah from Iloilo initially got confused because she thought her qualifying period started from her pregnancy date.

She paid her voluntary contributions on time to secure her benefits.
⚠️ Common Mistakes When Computing the Semester of Contingency

SSS bases computations on your Expected Delivery Date, not your actual childbirth date. - ❌ Counting 12 months backward directly from the EDD
You must first identify your semester (6 months), then count 12 months before it. - ❌ Including the semester in the qualifying period
Always exclude the semester of contingency when calculating. - ❌ Not verifying with a calculator
Manual computation can be tricky — avoid mistakes by using the online calculator.

âť“ FAQs About the Semester of Contingency
1. Why does SSS use the semester system instead of months?
Because benefits are calculated quarterly to align with contribution posting schedules.
2. What happens if my EDD changes?
Your semester and qualifying period will also adjust, so always base your computation on your updated medical certificate.
3. Is the semester the same for all benefit types?
No. The semester of contingency applies differently for sickness, disability, or maternity — always follow SSS maternity rules.
4. Can I use my actual delivery date if I give birth earlier?
SSS still uses your EDD, but if the actual date is significantly different, update your record immediately.
5. What if my qualifying period overlaps with unpaid months?
You must have at least 3 valid contributions within the counted 12 months — missing payments can disqualify your claim.
