Work out redevelopment share instantly with clear inputs, formula shown and shareable results.
In a redevelopment offer the existing occupier receives their current carpet area plus an additional percentage, together with a corpus payment for hardship and future maintenance. Valuing the new flat at post-redevelopment rates and adding the corpus gives the total benefit, which is what should be compared against competing developer offers.

This calculator takes 4 inputs: Existing carpet area, Additional area offered, Market rate after redevelopment, Corpus and hardship payment. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
