When negotiating a job offer, the headline number is almost always the Cost to Company (CTC). It sounds impressive, and it is the number you tell your friends and family. However, CTC is not your salary. It is the total expense the company incurs to keep you employed.
The gap between your CTC and the actual cash that hits your bank account every month is often shockingly large. This gap is filled with employer contributions, employee provident fund (EPF) deductions, professional taxes, income tax (TDS), and sometimes bloated allowances that are difficult to claim.
If you plan your budget, home loan EMIs, or investment SIPs based on a percentage of your CTC, you will likely face a severe cash crunch. You must calculate your true 'in-hand' salary to make responsible financial commitments.
