The retirement income gap is the difference between what you'll spend each month in retirement and what guaranteed income sources (pension, rental, part-time work) will provide.

📐 How the Income Gap is Calculated

Monthly Gap = Future Monthly Expenses − Guaranteed Monthly Income

Future Expenses = Current Expenses × (1 + Inflation)^Years to Retirement
Corpus Needed = Monthly Gap × 12 × 25 (4% rule) or Monthly Gap × 12 × 28.57 (3.5% rule)

Example: ₹60,000 today, retiring in 25 years at 6% inflation → Future expense = ₹2.57L/month. Pension ₹50,000/month. Gap = ₹2.07L/month. Corpus needed = ₹6.2 Cr.

🛠️ How to Use

Step 1: Enter your current age and expected retirement age.
Step 2: Enter current monthly expenses (in today's rupees).
Step 3: Enter expected guaranteed monthly income at retirement.
Step 4: See your inflation-adjusted monthly shortfall and corpus needed.
