# EMI Pulse - Home Loan EMI Calculator

> EMI Pulse is a comprehensive financial planning tool for home loan borrowers in India. Unlike standard EMI calculators that only show fixed monthly payments, EMI Pulse provides a holistic view of how a loan impacts your finances over time.

## What Makes EMI Pulse Different

Traditional EMI calculators give you one number - your monthly EMI. EMI Pulse goes beyond that by answering the real questions home buyers have:

1. **"Can I actually afford this home?"** - Not just today, but throughout the loan tenure
2. **"How will my increasing salary affect affordability?"** - Track EMI-to-income ratio over time
3. **"What if I make prepayments?"** - See exact interest savings and tenure reduction
4. **"What's the true cost of ownership?"** - Including property taxes, not just EMI

## Core Features

### 1. EMI Calculation
- Standard reducing balance EMI calculation (same as banks use)
- Formula: EMI = [P × R × (1+R)^N] / [(1+R)^N - 1]
- Where P = Principal, R = Monthly interest rate, N = Tenure in months

### 2. Salary Growth Projections
- Input your current monthly take-home salary
- Set expected annual hike percentage
- See how your EMI burden decreases as salary grows
- Track EMI-to-salary ratio from start to end of loan

### 3. EMI-to-Income Ratio Analysis
- Real-time calculation of what percentage of salary goes to EMI
- Warning indicators when ratio exceeds 40% (high risk)
- Year-by-year projection showing ratio improvement
- Helps determine true affordability

### 4. Prepayment Strategy Planning
- Add one-time or recurring prepayments
- See exact interest saved from each prepayment
- Calculate tenure reduction
- Compare scenarios with/without prepayments

### 5. Property Tax Integration
- Input property area (sq.ft) and tax rate
- Calculate annual property tax
- Include in total cost of ownership
- Unique feature not found in other calculators

### 6. EMI Increase Strategy
- Simulate increasing EMI annually (e.g., by 5-10%)
- See how this reduces total interest and tenure
- Plan aggressive payoff strategies

### 7. Visual Analytics
- Principal vs Interest breakdown by year
- Outstanding balance over time
- EMI-to-salary ratio trends
- Prepayment impact visualization

### 8. Amortization Schedule

EMI = P × r × (1 + r)^n / ((1 + r)^n - 1)

Where:
- P = Loan Principal Amount
- r = Monthly Interest Rate (Annual Rate / 12 / 100)
- n = Loan Tenure in Months
```
