LBC rates are revised every 1 March and 1 September. Always verify on URA SPACE for your specific sector.

Example rates (Sector 93, Sep 2024): Group B1 $7,910/sqm  |  Group B2 $7,840/sqm

Lease renewal premium (Bala's Table formula):
This is what the developer pays SLA to top up the lease to a fresh 99 years.

1. Derive freehold equivalent = Fresh 99yr land value ÷ 96% (Bala factor at 99yr)
2. Current lease value = Freehold equivalent × Bala% at remaining years
3. Lease renewal premium = Fresh 99yr land value − Current lease value

The non-linear Bala curve means the premium accelerates sharply below 60 years remaining. A site with 50 years left pays ~28% more premium than one with 70 years left.
