A collection of financial calculator components for React applications.

## Installation

```

## Available Calculators

The package provides the following calculators:

1. **LumpsumSIPCalculator** - Calculate the future value of a lumpsum investment combined with a Systematic Investment Plan (SIP).
2. **RetirementCalculator** - Calculate retirement corpus needed and monthly investments required based on expenses.
3. **StepUpSIPCalculator** - Calculate the future value of a SIP with annual step-up increments.

## Usage

### Basic Usage

```jsx
import React from 'react';
import { LumpsumSIPCalculator } from 'financial-calculators-react';

const MyFinancialApp = () => {
  return (
    <div className="app">
      <h1>Financial Tools</h1>
      <LumpsumSIPCalculator />
    </div>
  );
};

export default MyFinancialApp;
```

### Customizing Theme

All calculators accept a `theme` prop to customize the appearance:

```jsx
import React from 'react';
import { RetirementCalculator } from 'financial-calculators-react';

const MyFinancialApp = () => {
  const customTheme = {
    primary: "#1E40AF",     // Main color
    secondary: "#3B82F6",   // Secondary color
    accent: "#DBEAFE",      // Accent color for highlights
    background: "#F8FAFC",  // Background color
    textPrimary: "#1F2937", // Primary text color
    textSecondary: "#6B7280" // Secondary text color
  };

  return (
    <div className="app">
      <h1>Retirement Planning</h1>
      <RetirementCalculator theme={customTheme} />
    </div>
  );
};

export default MyFinancialApp;
```

## Important Note

This package requires you to provide implementations for the UI components used by the calculators. The following components need to be provided in your application:

- UI Components: CalculatorContainer, InputSection, ResultsSection, etc.
- UI Elements: InputField, SelectField, Button, ResultCard, etc.
- Chart Components: LineChart, BarChart, ChartToggle, ChartIcons
- Utility Components: ReportDialog, ReportOptions, etc.
- Utility Functions: formatCurrency, numberToWords, etc.
- Validation Functions: validateRequiredFields, validateNumericFields, etc.
- Report Generation: generateReport, downloadReport, sendReportViaWhatsApp

You can create a wrapper around this package that provides these implementations specific to your UI library of choice (Material-UI, Chakra UI, etc.).
