Storage build cost calculator
What it costs to build 10, 50 or 100 storage units in the UK — container site, conversion or ground-up build. Sourced ranges with the assumptions on show, and an honest "no benchmark exists" where that is the truthful answer.
Answers: How much capital do I need to open?
What it won’t do: It will not quote below the smallest published benchmark band, because stretching a source downward invents a number its author never stood behind.
Open the calculator →Self storage profitability calculator
Monthly and annual profit for a site, and the occupancy you need to break even — from your own unit count, licence fee and running costs, with StoreBay’s real published software price included in the model.
Answers: Will the site actually make money, and at what occupancy?
What it won’t do: It defaults business rates to zero rather than guessing, because rates depend on a site-specific rateable value and a made-up figure would produce a confident, wrong break-even.
Open the calculator →Self storage business rates calculator
The England business rates bill for a storage site: the right multiplier for your rateable value, Small Business Rate Relief and the taper — the line most storage business plans budget at zero.
Answers: What will business rates actually cost me?
What it won’t do: It is England only, said in three places. Wales, Scotland and Northern Ireland run different multipliers and reliefs, and quietly applying England’s numbers to them would be confidently wrong.
