Would you be better off buying a home or renting and investing the difference?

Buying a home is the biggest financial decision most people make, and 'rent is dead money' is only half the story. Buying comes with stamp duty, legal and moving costs, mortgage interest, repairs, insurance and selling costs – while a renter can invest the deposit and any monthly saving. This calculator follows both paths side by side, year by year for up to 30 years, using the same pot of cash and the same monthly budget. It shows your net worth on each path if you sold up (or cashed in) at the end of any year, the year buying pulls ahead, where the money goes, and how the answer changes with house prices and mortgage rates.
