Currency & Conversion Logic

The Indian Startup Funding Tracker manages financial data primarily in Indian Rupees (INR). This section outlines how the system handles currency conversion from USD and formats large financial figures into standard Indian units like Lakhs (L) and Crores (Cr).

Currency Conversion

While many startup funding deals are reported in USD, the platform normalizes all data to INR to provide a consistent analysis of the Indian ecosystem.

Updating Conversion Rates

The conversion rate is a static value used during the data generation process. To update the exchange rate:

1. Open config/currency.js.
2. Update the rate and date values.
3. Run the data generation script to re-calculate values across the dataset:

   npm run generate-data
   

The current application uses a reference rate of 1 USD = ₹83.50 (as of November 2025). This rate is displayed on the Analytics page to provide context for the trend charts.

Data Unit Convention

To maintain precision while keeping the data human-readable, funding amounts are stored using the following convention:

• Internal Unit: Lakhs (INR).
• Scale: 100 units in the data file equals 1 Crore (₹10,000,000).
• Undisclosed Deals: A value of 0 represents a deal where the amount was not publicly disclosed.

Formatting Utilities

The lib/utils.ts file provides helper functions to handle the display logic for these amounts.

formatFundingAmount

Converts a raw numeric value (in Lakhs) into a formatted string with the appropriate Indian currency suffix.

Signature:

function formatFundingAmount(amount: number): string

Parameters:

• amount: The funding amount in Lakhs.

Returns:

• A string formatted with the ₹ symbol and the most appropriate unit (L, Cr, or B).
• Returns "Not Disclosed" if the amount is 0, null, or undefined.

Formatting Logic: | Amount (in Lakhs) | Display Format | Example Input | Example Output | | :--- | :--- | :--- | :--- | | 0 | String | 0 | "Not Disclosed" | | < 100 | Lakhs (L) | 50 | ₹50L | | 100 - 99,999 | Crores (Cr) | 1250 | ₹12.5Cr | | ≥ 100,000 | Billions (B) | 200000 | ₹2.00B |

Usage Example:

import { formatFundingAmount } from "@/lib/utils"

// Displaying a Series A deal of 4000 Lakhs
const displayAmount = formatFundingAmount(4000); 
// Output: "₹40Cr"

isFundingDisclosed

A utility to check if a deal has a valid monetary value attached to it. This is used to filter data for charts and aggregate statistics (like "Total Funding") where undisclosed deals should not be treated as zero-value.

Signature:

function isFundingDisclosed(amount: number): boolean

Usage Example:

const disclosedDeals = fundingData.filter(deal => isFundingDisclosed(deal.amount));

Analytics Logic

When calculating trends in the AnalyticsDashboard component, the system specifically filters for disclosed amounts to avoid skewing "Average Deal Size" or "Total Funding" metrics. Charts for "Deal Count" include all deals, whereas monetary charts (Bar/Line/Pie) represent the sum of amount / 100 to convert the base Lakhs into Crores.
