Base44 tools — calculators for cost and migration.

Base44's own plans run from $0 (Free) to $200 a month (Elite) on monthly billing, or $16 to $160 a month for the paid plans billed annually, as read on base44.com/pricing on 23 September 2026. What you pay in practice adds the services you connect, which Base44's pricing FAQ says bill you directly, plus AI use beyond the plan's credits, integration fees at your user volume and the engineering time the platform takes. The cost calculator itemises those lines for your own plan, usage and integrations rather than quoting a market average.

They are estimates built on stated assumptions. Plan prices are Base44's published monthly-billing prices, and the migration costs are the prices we charge for that work. Everything else — the AI-usage bands, the per-integration costs, the volume surcharge, the engineering-time band and the target-stack run costs — is a fixed assumption, listed on its calculator's page. If your real numbers differ, the output is off by the same amount, so check the assumptions against your own invoices.

Not unless you ask. Both calculators compute in your browser, show the result without an email address, and send nothing while you change the inputs. If you use "Send me my estimate" or "Send me my ROI model", your email address and a one-line summary of your inputs and result are emailed to our team so we can reply. We treat that as an enquiry, not a sign-up, and do not add it to a marketing list. If you want an engineer to walk you through the assumptions, start at /audit or /contact.

Sometimes. The honest answer depends on whether you are paying for things base44 gives you (rapid iteration, the AI agent's early-build speed, the integrations that ship in the box) or paying for things you no longer need (the AI agent on a stable codebase, the credit ceiling on a high-traffic app, the SLA gap on an enterprise deal). The ROI calculator puts the cash side in months: it calls a payback inside 12 months a strong case to move and inside 24 months worth it if you plan to keep the app. Past that, migrate only if lock-in, compliance or SLA risk dominates.

Because we only ship a calculator when we can state every assumption behind it. The cost and ROI tools are built on Base44's published plan prices, our own published service prices and assumptions listed on each tool's page. We are working on a credit-burn forecasting tool and a security-posture self-check; both will land here when the underlying data is solid. If there is a calculation you keep doing on the back of a napkin, tell us at /contact and we will probably build it.

Fair question. The bias would be to make base44 look cheap to drive build work or look expensive to drive migration work. We do both — fix, build, migrate — so neither bias serves us. The calculator outputs a number; what to do about it is the conversation. If the number says stay, we will tell you to stay. The audit tier exists for exactly that scenario.

Talking to engineers who have shipped on this platform. The calculators are decision-aids, not decisions. They will tell you the bill is too high or the migration pays back in seven months; they will not tell you whether your specific webhook flakiness is fixable in a week or symptomatic of a deeper architecture problem. Run the numbers, then book a $497 audit if the answer points to action.
