How to Compute Your SSS Salary Loanable Amount
Learn how SSS computes your salary loan based on your latest posted MSCs, how to estimate a 1-month or 2-month loan, and why the money you actually receive can be lower than the approved amount.
Quick answer
A 1-month salary loan is generally the average of your latest 12 posted MSCs, rounded to the next higher MSC. A 2-month salary loan is generally twice that average, subject to SSS rules and deductions.
Quick answer
SSS computes a salary loan from your latest 12 posted Monthly Salary Credits (MSCs). For a 1-month loan, SSS uses the average of those 12 posted MSCs, rounded to the next higher MSC. For a 2-month loan, SSS generally uses twice that average, rounded the same way. The final approved amount can still be reduced by fees, pro-rated interest, and old short-term loan balances.
1-month loan
Average of latest 12 posted MSCs, rounded up to the next higher MSC.
2-month loan
Twice the average of latest 12 posted MSCs, rounded under the same rule.
Actual cash received
Usually lower than the approved loan amount after deductions.
Use the calculator instead of guessing

Main formula for computing your loanable amount
The core idea is simple: SSS looks at your latest 12 posted MSCs, not just one month and not just your current income. Then it uses the average of those posted MSCs to determine the base amount.
Simple formula
- 1-month loan = average of latest 12 posted MSCs, rounded to the next higher MSC
- 2-month loan = 2 × average of latest 12 posted MSCs, rounded to the next higher MSC
Difference between a 1-month and 2-month salary loan
| Loan type | How it is computed | Main requirement signal |
|---|---|---|
| 1-month loan | Average of latest 12 posted MSCs, rounded up to next higher MSC | Usually tied to the 36 posted contributions rule |
| 2-month loan | Twice the average of latest 12 posted MSCs, rounded up to next higher MSC | Usually tied to the 72 posted contributions rule |
What “latest 12 posted MSCs” really means
This is where many people get confused. SSS is not simply asking for your 12 latest payments in any rough sense. It is specifically using your 12 latest posted Monthly Salary Credits under the regular SS program.
Posted matters
If a contribution is not yet posted in the system, it may not help your salary loanable amount yet.
MSC matters more than raw cash paid
The loan formula is based on MSCs, not just the peso amount you remember paying.
Why your net proceeds are lower than your approved amount
One of the biggest surprises for borrowers is that the amount approved by SSS is not always the amount that actually lands in the bank.
1% service fee
This is charged and deducted from the loan proceeds.
Pro-rated interest
Interest up to the month before first amortization is deducted in advance.
Previous short-term loan balance
Outstanding balances can reduce what you actually receive.
Simple examples
Example 1: 1-month loan
If your 12 latest posted MSCs average to ₱20,000, then your 1-month loanable amount is generally based on ₱20,000, subject to SSS rules and deductions.
Example 2: 2-month loan
If your 12 latest posted MSCs average to ₱20,000 and you qualify for a 2-month loan, the base approved amount is generally ₱40,000 before deductions and limitations.
Common mistakes when estimating salary loanable amount
Using contribution pesos without converting to MSC
The formula is built on MSCs, not just remembered cash payments.
Assuming net proceeds = approved amount
Deductions can significantly reduce what actually gets credited.
Ignoring 1-month vs 2-month qualification
This changes the base formula a lot.
Using not-yet-posted records
If it is not posted yet, it may not help your estimate.
Need backup funds while comparing your loanable amount?
If your computed salary loan may be lower than expected and you still need short-term flexibility for urgent expenses, a backup option may help.
