How to use the No-Code vs Custom Development Calculator
This calculator compares the total cost of running an app on a no-code platform such as Bubble or Webflow with building it as custom software, over 2, 3 or 5 years. It prices each path from fixed allowances tied to the app's complexity, then adds a recommendation that also weighs user count and horizon. It is for founders and product owners deciding how to build a first version.
Step by step
-
Set expected users
Drag Expected users between 100 and 500,000 in steps of 100. It starts at 5,000. Users do not change either cost; they only feed the recommendation.
-
Choose app complexity
Under App complexity, pick Simple (forms, CRUD, a dashboard), Standard (auth, payments, integrations) or Complex (real-time, heavy logic, scale). Standard is the default. Complexity sets both the no-code setup allowance and the custom build estimate.
-
Pick a time horizon
Choose 2 yrs, 3 yrs or 5 yrs under Time horizon. The default is 3 years, and both totals use the same span.
-
Enter the platform fee
Type your monthly subscription in No-code platform cost / month. The default is $300 and the arrows move it in steps of $50. Include the add-ons and usage charges you expect to pay.
Reading the result
- No-code TCO is the monthly fee × 12 × years plus a one time setup of $8k, $20k or $45k for Simple, Standard or Complex. Defaults: $10,800 + $20,000 = $30,800, shown as $31k.
- Custom TCO is a build estimate of $40k, $100k or $220k by complexity, plus 18% of that build for every year. Defaults: $100,000 + $54,000 = $154,000, shown as $154k.
- The large number under Cost difference over your horizon is the gap, $123,200 with the defaults, and the line below it names the cheaper path. The cheaper card is highlighted and the bars compare both totals.
- The verdict leans custom when the app is Complex, the horizon is 5 years or users reach 50,000. It favors no-code when the app is Simple, the horizon is 3 years or less and users are 20,000 or fewer. Anything else, including the defaults, is shown as a toss-up.
Tips and common mistakes
- The verdict can disagree with the cheaper total. That is deliberate: it weighs platform limits and lock in that the cost lines do not price.
- You cannot type your own build quote. If you already have one, compare it with the Custom TCO card by hand, adding 18% of it for each year.
- The platform fee stays flat however many users you enter, so set it to the plan you would need at your expected user count, not the starter plan.
- Try the same inputs at 2 yrs and at 5 yrs. Subscriptions and upkeep both grow every year, and the gap between them can change sides.

How it works
Choosing no-code versus custom development is rarely just a price comparison, it is a bet on how far a platform can carry your product before you outgrow it. This calculator models both paths over your chosen horizon so you can see the total cost of ownership side by side, then layers a recommendation on top that accounts for the things a spreadsheet misses: the feature ceiling, per-record pricing, and vendor lock-in.
The no-code path adds a one-time setup effort (roughly $8k simple, $20k standard, $45k complex to configure and design the app) to your recurring platform subscription across the full horizon. The custom path takes a build estimate ($40k, $100k, or $220k by complexity) and adds annual maintenance at an industry-standard 15-20% of the build cost per year, we use 18%. Whichever total is lower wins the sticker-price comparison, but the verdict weighs ownership too.
The guidance flips to custom whenever complexity is high, the horizon is long, or your user count is large, because those are precisely the conditions where no-code platforms hit walls, usage-based pricing climbs, you cannot ship a feature the platform does not support, and migrating off later costs more than building right the first time.
No-code TCO = (monthly × 12 × years) + setup | Custom TCO = build + (build × 18% × years)
For a deeper build estimate, use the software development cost calculator, or compare buying an off-the-shelf tool against building with the build vs buy calculator.

FAQs
When does no-code stop making sense?
No-code loses its edge when complexity, scale, or your time horizon grows. Real-time features, heavy custom logic, deep integrations, and large user counts push you past what platforms like Bubble or Adalo handle gracefully, and their usage-based pricing starts to outweigh the savings. That is the ceiling the calculator flags as a reason to lean custom.
Why does the calculator add 18% a year for custom software?
Ongoing maintenance, bug fixes, security patches, dependency upgrades, and small improvements, typically runs 15-20% of the original build cost per year. Using 18% keeps the custom estimate honest, since the build price alone understates the true cost of ownership over a multi-year horizon.
Can I start on no-code and move to custom later?
Yes, and it is often the smart play for a simple MVP on a short horizon. You validate the idea fast and cheap, then re-platform to custom code once traffic, complexity, or the roadmap justifies it. Just plan the migration path early so the switch is a deliberate step, not an emergency.
