How much does it cost to build a SaaS MVP?

The cost to build a SaaS MVP runs from about $15k with a freelancer to $150k+ with an agency, depending on scope and how you buy the engineering. On the devkyn subscription it runs on a plan matched to the workload, and most MVPs take six to eight weeks, so you're paying for roughly one and a half to two active months rather than a fixed lump sum.

How long does it take to build a SaaS MVP?

Most SaaS MVPs take six to eight weeks of focused senior engineering. A single-workflow tool is faster. Something with team accounts, permissions, and integrations takes longer. On a subscription you see a deployed increment every week instead of one big reveal at the end. The SaaS MVP Build page has the week-by-week breakdown.

What changes the price of an MVP build?

Scope is the biggest lever. How many workflows, whether billing and integrations are in v1, and how much product logic there is. A ready design and a deliberately narrow first version cut cost under any model. The subscription keeps this honest because you reprioritize mid-build and pause between phases instead of paying a change order.

What does a SaaS MVP cost besides the engineering?

Hosting, a managed database, and transactional email usually run $20 to $200 a month before real traffic. Stripe takes its published rate on every charge. Error tracking, analytics, and any API you depend on sit on free tiers until usage grows. Add terms and a privacy policy, plus a designer if you want custom screens. None of it is large next to engineering, and all of it arrives in month one.

Should I get a fixed-price quote for an MVP?

A fixed bid buys certainty and charges for it. The agency prices in the risk that scope moves, then bills a change order when it does, and scope always moves on a first version. A monthly rate you can pause puts that flexibility on your side, but it won't give you one contracted number before work starts. If your board needs that number, take the fixed bid and go in knowing what the change orders cost.

Is a subscription cheaper than an agency for an MVP?

Often, yes, though the honest answer is that it depends on scope. A plan matched to the workload with no contract usually beats a $30k–$150k+ agency lump sum for a first version, and you skip the account-manager overhead and the change-order fees. If you need several engineers in parallel to hit a hard deadline, an agency or a team genuinely fits better, and we'll say so.

What do I own when the build is done?

Everything. Code ships into your repo and your cloud account as it's built, not held behind a final payment. You own the codebase, the deploy pipeline, and the accounts, so leaving is never a negotiation. That holds whether you continue on the subscription for the next phase or take it fully in-house.

Cost guide - SaaS MVP Development Cost

A SaaS MVP is a month-plus build rather than a task, so the cost to build a SaaS MVP is a range and not a sticker price. What you pay comes down to how you buy the engineering. A fixed-bid agency, a freelance marketplace, a full-time hire, a no-code tool, and a senior engineer on a flat monthly subscription all price the same six-to-eight-week build very differently. Below are the honest ranges, the phases behind them, the costs founders hit in month one that were never in the quote, and what you own at the end. The SaaS MVP cost estimator further down maps your scope to a week range and a phase plan before you talk to anyone.

The honest options, compared

Most SaaS MVPs land in six to eight weeks of focused senior engineering. Those weeks are the real driver of SaaS MVP development cost and everything else is packaging. An agency wraps them in a project team and a lump-sum quote. A freelancer hands you the sourcing and the management. A full-time hire is months of recruiting before a line ships. A subscription is the middle most founders want, with one vetted senior engineer, month to month, no contract.

Option	Typical cost	Rough timeline	What to know
MVP development agency	$30k–$150k+ fixed bid	2–5 months	A project team and a lump-sum quote. Scope is predictable, but you pay for account managers and juniors, and change orders cost extra.
Freelancer / marketplace	$15k–$80k, variable	1–4 months	Cheaper hourly, but you do the sourcing, vetting, and management, and freelance handoffs are where builds stall at 70% done.
In-house hire	$130k–$220k/yr + ramp	2–4 months to hire	The right call once there's a steady roadmap. Until then it's months of recruiting and a salary you carry through the quiet stretches.
No-code (Bubble, etc.)	$0–$10k in tooling	Days to weeks	Fastest and cheapest way to validate an idea, until custom logic, real billing, or scale hit the ceiling and you rebuild it anyway.
devkyn subscription	Variable by plan	Variable by scope	One senior, founder-led engineer builds it week by week on a flat monthly rate you can pause. The selected plan is the monthly price, not the total. Most MVPs run a couple of active months, and everything ships into your repo.

About that monthly number

To be clear about the engagement, the selected monthly plan is the flat subscription the build runs on and not a fixed project total. A typical six-to-eight-week SaaS MVP is roughly one and a half to two active months of subscription. You pay for the weeks the build is active, you can pause between phases, and no contract locks you into a lump sum. If you want a single number to budget against, take the plan rate and multiply it by the active months the scope calls for.

Rough timelines by build type

Cost tracks time on the subscription, so the honest way to estimate is by build. These are the typical ranges for real devkyn builds:

Build	Typical timeline
SaaS MVP Build	6–8 weeks typical	See the build →
AI Product Build	6–10 weeks typical	See the build →
Marketplace Platform	8–12 weeks typical	See the build →

Where the money goes in an MVP build

Cost tracks weeks of senior engineering, so the useful way to read any quote is by phase. This is how a six-to-eight-week SaaS MVP spends its time and which phases move the number most.

Scoping, before anyone bills. A call and a written scope covering the one workflow the product has to nail, who logs in, and what they pay for. It costs nothing at this stage and it is the largest single lever on the total. A first version that starts narrow finishes in six weeks. One that starts broad finishes in twelve.
Foundations and auth, about 1 to 2 weeks. Data model, tenancy, accounts, and a deployable skeleton live behind your domain. These decisions are cheap to change now and expensive to change in week six, which is why the phase gets front-loaded instead of trimmed.
Core product, about 2 to 3 weeks. The main workflow and the dashboard users live in. This is the biggest block of engineering in most MVPs, and it is the block that grows when a second workflow gets added to v1.
Billing and launch, about 1 to 2 weeks. Stripe checkout, the customer portal, webhooks, plan gating, onboarding, error handling, and a staging run. Founders underestimate billing more than any other phase. Proration, failed payments, and upgrade paths are what separate a paying product from a demo.

What to budget for besides engineering

Engineering is the biggest line and it is not the only one. These are the costs that show up in month one and were never in the build quote.

Design. If you don't have Figma screens, either budget for a designer or accept a clean interface built from a component library. Both work for a first version. Only one of them costs extra.
Hosting and infrastructure. A pre-revenue SaaS on Vercel or a VPS, with managed Postgres and transactional email, usually runs somewhere between $20 and $200 a month until real traffic arrives.
Payment processing. Stripe's published US card rate is 2.9% plus 30 cents per successful charge, with higher rates on international cards and a separate fee if you switch on Stripe Tax.
Third-party services. Error tracking, product analytics, an email provider, and any API the product depends on. Most have free tiers that carry an MVP, and the bill arrives when usage does.
Legal. Terms, a privacy policy, and a data processing agreement if you sell to companies. SOC 2 is a later and much larger spend, not an MVP line item.
Your own hours. Plan on an hour or two a week reviewing increments and making the product calls only a founder can make. Builds slip when that hour doesn't happen.

When a subscription is the wrong way to buy this

The subscription fits a month-plus build with one senior engineer. Here is where it doesn't fit, so you can go price the right thing instead.

You need a signed lump sum up front. If a board or an investor wants one contracted number before work starts, a fixed-bid agency gives you that and a subscription doesn't. You're trading change-order fees for the certainty.
You need several engineers in parallel. A hard external deadline that only parallel work can hit calls for an agency or a team, not one engineer. We'll say so on the call rather than stretch this into a shape it isn't.
You have a handful of small tickets. A build is a month-plus engagement by design. If the work is a short list of fixes, task-mode work or a freelancer for a week costs you less.
Nobody has asked for it yet. If the idea is still unvalidated, a landing page with a waitlist or a no-code prototype answers that question for a fraction of a build. Come back once people are asking for the real thing.

What changes the price

How much product there is. A single-workflow tool is faster and cheaper than something with teams, roles, and permissions.
Whether billing, third-party integrations, or real-time features are in the first version or deferred until after launch.
How ready the design and spec are. A clear Figma and a narrow scope shave weeks off any of these options.
Whether you're validating a brand-new idea, which argues for starting narrow, or rebuilding a no-code prototype that already proved demand.
How many active months the build runs. On a subscription the total is the plan rate times those months, so pausing between phases lowers it.
