MONEY / OFFER ECONOMICS
What do you keep
from each sale.
Start with your price. Subtract the costs of making, delivering and selling your offer. See exactly what is left.
What should I include?
Start with the price of one sale, then subtract its costs. For a product, that might be materials, packaging, shipping and payment fees. For a service, it might be delivery work, contractor costs, payment fees and the cost of finding that customer.
Include a value for your own time if you want the result to account for it. If a fee is a percentage, convert it to a dollar amount for this sale first. Use your actual costs or clearly estimated amounts.
This result is what is left after the costs you listed. Tax and other business costs still need to come out of it. It is not your final take-home pay. There is no monthly sales or break-even calculation here.
