Convert the line chart to percentage growth

To convert the line chart of transaction prices for properties like Carmi Mansions, The Pinnacle@Duxton, and Enchante into percentage growth, you would need to calculate the year-over-year (YoY) or quarter-over-quarter (QoQ) percentage change in prices.

Here’s a simplified approach:

Steps to Calculate Percentage Growth

1. Obtain Price Data: Gather the transaction prices for each quarter or year for the respective properties.
2. Calculate Percentage Change:
   • For YoY growth: ((\text{Current Price} - \text{Previous Year's Price}) / \text{Previous Year's Price} \times 100)
   • For QoQ growth: ((\text{Current Price} - \text{Previous Quarter's Price}) / \text{Previous Quarter's Price} \times 100)

Example

• If the price of a unit in Carmi Mansions was $1,000,000 in Q4 2024 and $1,039,000 in Q1 2025, the QoQ growth would be:
  ((1,039,000 - 1,000,000) / 1,000,000 \times 100 = 3.9%)

General Trends

• As of the latest data, Singapore house prices grew 3.9% YoY in December 2024, which can serve as a benchmark for overall market trends.
• The Residential Property Price Index has been increasing, reaching an all-time high of 211.50 points in the first quarter of 2025.

Visual Representation

• Plot the percentage growth values on the line chart instead of the absolute prices. This will show the rate of change over time, providing a clearer picture of the growth trends for each property.

You can use the transaction data available on EdgeProp Singapore to calculate and plot these percentage growths for a more detailed analysis.
