Online business cost calculator

Replace every illustration below with your own quote or documented assumption. This calculator runs entirely in your browser: it stores nothing and sends no inputs to Locus.

Not a quote, average, or financial forecast. Currency is USD. Taxes, chargebacks, returns, insurance, compliance, and founder time can materially change the result. Use a qualified professional where appropriate.

Formation and permits ($, one-time) Use your state/local government quote. Samples, setup, and design ($, one-time) Illustration only; include samples or contractor setup. Initial inventory ($, one-time) Use zero for a service or inventory-free product. Domain ($ per year) Amortized over 12 months in ongoing cost. Software and platform ($ per month) Site, store, email, CRM, automation, and similar tools. Marketing test cap ($ per month) A hard cap, not assumed revenue. Contractors and insurance ($ per month) Include recurring professional and risk costs. Expected monthly sales ($) A scenario input, not a prediction. Expected monthly orders Use qualified leads or invoices if that better fits your model. Variable fee (% of sales) Replace with the combined official rate that applies to you. Per-order fee ($) Replace with the applicable official fee. Contingency (% of costs) A planning buffer, not insurance against loss.

Estimated first-month cash need $0.00

Estimated ongoing monthly cost $0.00

First month = one-time costs + monthly fixed costs + variable fees + contingency.
Ongoing = domain ÷ 12 + monthly software + marketing + operations + variable fees + contingency.
