Salary Increment: Meaning, Appraisal Letter Format & Calculation (2026)
Quick answer: A salary increment is an increase in an employee’s salary, usually granted after a performance appraisal. It is typically expressed as a percentage of the current salary — for example, a 10% increment on a ₹6,00,000 CTC adds ₹60,000, taking it to ₹6,60,000. Increments reward performance, adjust for inflation, and aid retention.
Key facts
- Salary increment: a raise in pay, usually annual and performance-linked.
- Appraisal: the performance review that determines the increment and rating.
- Appraisal/increment letter: the formal document confirming the new salary.
- Variable pay: a performance-linked bonus component, separate from the fixed increment.
- Increment formula: New salary = Current salary × (1 + increment% ÷ 100).
What is a salary increment?
A salary increment is the amount by which an employee's salary is raised, most often once a year after the appraisal cycle. It reflects performance, market benchmarks and cost-of-living changes. Increments are communicated through an increment letter or appraisal letter and revise the employee's CTC (Cost to Company).
Salary increment vs appraisal vs variable pay
| Term | Meaning |
|---|---|
| Increment | The actual raise in fixed salary |
| Appraisal | The performance evaluation that decides the increment |
| Variable pay | Performance-linked bonus, paid on top of fixed salary |
| CTC | Total cost to company, including fixed + variable + benefits |
How is salary increment calculated?
Formula: New Salary = Current Salary × (1 + Increment % ÷ 100). Example: a 12% increment on ₹8,00,000 = ₹8,00,000 × 1.12 = ₹8,96,000 (an increase of ₹96,000). To find the increment percentage: Increment % = ((New − Old) ÷ Old) × 100.
Average annual increments in India typically range around 8–10%, with high performers and in-demand tech/digital roles often receiving more. Figures vary each year by industry, company performance and economic conditions, so treat sector benchmarks as a guide rather than a guarantee.
