Sick Leave Benefit Calculation: Complete 2025 Guide
Learn how to calculate your sick leave benefit value. Understand INSS rules, requirements, and use our calculator for accurate simulations.
Sick leave benefit is one of the most requested benefits from INSS (social security), but many insured individuals have questions about how to calculate the amount they will receive. This benefit guarantees monthly income for workers temporarily unable to perform their professional activities.
For 2025, the calculation rules remain the same as established by Law No. 8,213/91, but it’s essential to understand how INSS (social security) determines the benefit salary to avoid surprises in the amount received.
What is sick leave benefit
Sick leave benefit is a social security benefit granted to insured individuals who prove temporary incapacity for work due to illness or accident. The benefit is paid monthly while the incapacity persists.
Who is entitled
The following insured individuals who meet basic requirements are entitled to sick leave benefit:
- Employed workers (formal employment)
- Individual contributors (self-employed)
- Special insured (rural workers)
- MEI (micro-entrepreneur) with up-to-date contributions
- Optional contributors who contribute voluntarily
Required conditions
To receive the benefit, the insured must meet these conditions:
- Minimum grace period: 12 monthly contributions
- Proven incapacity: through INSS (social security) medical examination
- Insured status: be current with contributions or within the grace period
- Not engage in paid work: during benefit receipt
Important: Work accidents and some serious diseases waive the grace period requirement.
How the amount is calculated
Sick leave benefit calculation follows a specific methodology based on the benefit salary. This amount corresponds to 91% of the average of the highest contribution salaries within the basic calculation period.
Benefit salary
The benefit salary is calculated considering 80% of the highest contributions from the insured since July 1994 or from the beginning of contributions, if later.
To find this amount, INSS (social security):
- Lists all contributions from the basic period
- Discards the 20% lowest values
- Calculates the arithmetic mean of the remaining 80%
- Applies the 91% coefficient
Basic calculation period
The period considered varies according to the type of insured:
- Employees: since July/1994 or beginning of contributions
- Individual contributors: last 15 years before the incapacity start date
- Special insured: based on optional contributions
Step-by-step calculation
Highest contribution salaries
The first step is to identify all contributions within the basic calculation period. INSS (social security) organizes these values in descending order and selects the highest 80%.
Example: If the insured has 120 contributions, the highest 96 will be considered (80% of 120).
Coefficient application
After calculating the average of the highest salaries, the coefficient is applied:
- Benefit salary = average × 0.91
- Sick leave benefit amount = 91% of benefit salary

Minimum and maximum amounts
Sick leave benefit has established limits for 2025:
| Limit | Amount |
|---|---|
| Minimum | R$ 1,412.00 (minimum wage) |
| Maximum | R$ 7,786.02 (INSS ceiling) |
Protection rule
There’s protection for insured individuals with few registered salaries. If the calculation results in an amount below minimum wage, the benefit will be R$ 1,412.00.
Social security ceiling
Even if the calculation results in a higher amount, sick leave benefit cannot exceed the INSS (social security) ceiling of R$ 7,786.02.
Practical calculation example
Let’s calculate the sick leave benefit for an insured with the following characteristics:
Insured data:
- 60 contributions in the basic period
- Sum of 48 highest salaries: R$ 192,000.00
- Average of highest 80%: R$ 4,000.00
Calculation:
Step 1: Average = R$ 192,000 ÷ 48 = R$ 4,000.00 Step 2: Benefit salary = R$ 4,000 × 0.91 = R$ 3,640.00 Result: Sick leave benefit of R$ 3,640.00
