How the startup costs calculator works
Build a one-page picture of how much funding you need to launch. List your one-off setup costs and your monthly running costs, and the calculator helps you estimate the cash required to get to launch and through the early months before the business is self-sustaining.
Getting this right — and choosing the correct business structure from day one — avoids expensive mistakes. Our business start-up service guides you through it.
