Formula

((New - Old) / Old) × 100। ₹35,000 to ₹40,000: +14.3%। Average Indian salary increase: 8-12%/year (among highest globally!)। If below inflation (~5-6%): real purchasing power loss।

Negotiation

Minimum ask: inflation rate (5-6%)। Good: 10-15%। Job switch: 30-50% (Indian IT standard!)। Always negotiate — first offer is never final।
