Now this enables you to perform basic calculations on how long your savings will last. If you spend 1000 monetary units per month, 12k monetary units will last you entire year, and so on. Base your budget on burn rate that gives you balance between comfort and frugality.

Do a financial review every month. Look into how much you are spending for each category of expenses and see if it can be reasonably reduced. Are you within budget? Also recalculate runway duration that your stash of personal savings converts into. Calculate the date of your money running out under your current burn rate if you made zero new money. Write all of this down to keep track of your financial situation during the year.

Avoid taking out money out of your new company until you reach the point of being able to do so without hurting the business. Keep your personal funds separate from business funds even if you are the sole owner of your startup.
