Budgeting calculator
Use the monthly budget calculator to see how much you have left over after all your monthly commitments are taken into consideration. This will help provide an idea of how much you could afford towards a mortgage on a monthly basis.
When filling in the planner, try to think about everything you earn, spend and save in an average month. Be honest, and where items you think of aren't included on the list, make sure you add them into the 'other' category.
