The budget is defined as an estimate of income and expenditure for a set period of time. The ideal budget of a business will allow you to cover your expenses and give you a profit.
in order to decide on the budget needed for a business, it is important to take into consideration both the incomes (what you get from selling or external support) and outcomes (what you spend on for creating your products or services).
Outcomes
Outcomes are the costs needed in order to be able to produce a product or offer a service. The types of outcomes are totally dependable on the type of activity you do and its requirements. A general list would include:
Materials and goods
Needed raw materials
Other materials: gas, spare parts, stationary, consumables, etc
Third parties services
Rent, utilities, telecommunication, security, waste collection, etc
Insurance, maintenance and repairing, transportation, accommodation, etc
Publicity, consultancy, etc
Human resources
Salaries and taxes

In order to obtain profit, the outcomes should be smaller than the incomes. When establishing the price of your product or service, take into account all the expenses you have to create it (utilities, rent, salaries, materials, etc.) which leads us now to the incomes you can have from your business.
Incomes
The outcomes of a business consist of the money you can obtain by selling your products or services, from other types of financial activities or grants alike. Likewise for the outcomes, the incomes depend on the type of business you have, and a general list of them could be:
