This free tool estimates the resale price of any HDB flat in Singapore using a machine learning model trained on 227,000+ transactions from 2017 to present. It covers all 26 HDB towns and flat types — from 1 Room to Multi-Generation — and returns an instant price estimate based on location, storey, floor area, lease remaining, and proximity to amenities such as MRT stations, schools, hawker centres, and shopping malls.
The model achieves R² = 0.980 with a typical prediction error of around S$33,000, making it one of the most accurate publicly available HDB resale price calculators in Singapore.
