Break-even math for side projects

Monthly net = monthly revenue − monthly costs. Months to break even = remaining loss ÷ positive monthly net. For example, a $1,000 remaining loss and $200 monthly profit takes five months to recover.

How is the break-even forecast calculated?

Remaining loss is total spent minus total earned. Divide that loss by monthly revenue minus monthly costs to estimate the months to break even. The forecast assumes those monthly amounts stay constant.

What if monthly costs are higher than revenue?

Your loss keeps growing. The difference between monthly costs and monthly revenue is the extra revenue needed each month to stop that growth. Recovering past losses requires revenue above costs.

Which costs belong in a side-project budget?

Include hosting, domains, software subscriptions, advertising and other project expenses. Put past costs in total spent and ongoing costs in monthly costs. Use USD consistently across all fields.

Does this calculator save my financial data?

No. Calculations run in this page without an account and are not saved to your ledger. Create an account separately to track actual project entries and recurring costs.
