How much does it cost to build a SaaS in 2026?
Building it yourself with AI tools costs $0 to $50 a month. An AI venture platform costs $20 to $50 a month, though some add a 15-20% share of revenue. A developer or agency costs $5,000 to $50,000 for a first build. Below: what each route includes, the three costs almost everyone forgets, and the one expense that dwarfs all of them.

The short answer, by route
Three routes exist, and the honest headline is that two of them now cost about the same and the third costs two orders of magnitude more. First-year totals below assume a solo founder shipping one product, and exclude paid advertising and your own time.
| Route | Build cost | First-year total | Time to first version | Revenue share |
|---|---|---|---|---|
| DIY with AI build tools | $0–$50/month | $250–$650 | Hours to days | None |
| AI venture platform (flat fee) | $20–$50/month | $250–$600 | Hours to days | None |
| AI venture platform (revenue share) | $0–$50/month | $600–$5,400 | Hours to days | 15–20% of revenue |
| Developer or agency | $5,000–$50,000 one-off | $6,000–$60,000 | Weeks to months | None |
Platform pricing in the middle rows varies more than the ranges suggest, and the platform-by-platform comparison sets out who charges what. The range within each row is mostly about ambition rather than efficiency. A single-purpose tool sits at the bottom of its range; a product with user accounts, multiple integrations and a billing model sits at the top.
What you are actually paying for
Broken into line items, a first year of a small SaaS looks like this. Almost all of it is small, which is the point: the economics of starting changed, and the interesting question is no longer how to afford the build.
| Line item | Typical cost | Can you avoid it? |
|---|---|---|
| Build tool or platform | $0–$600/year | Free tiers exist, with the tool's badge on your app |
| Domain name | $10–$15/year | No, if you want to look like a business |
| Hosting | $0–$240/year | Free tiers cover early traffic; often included on platforms |
| Database | $0–$300/year | Free tiers are generous at low volume |
| Payment processing | 2.9% + $0.30 per transaction | No, once you have revenue |
| Transactional email | $0–$240/year | No, once you have users |
| Analytics | $0–$120/year | Free tiers are sufficient for a long time |
| Revenue share, if applicable | 15–20% of all revenue | Only if your platform does not charge one |
The three costs people forget
1. Payment processing
Roughly 2.9% plus 30 cents per transaction on standard online card payments. On a $20-a-month subscription that is about 4% of revenue, because the fixed 30 cents hurts disproportionately at small ticket sizes. It is unavoidable and it starts with your first sale, so build it into pricing rather than discovering it afterwards.
2. Maintenance
Software does not hold still. Dependencies need updating, security patches need applying, browsers change, and customers need support. Either the platform handles it as part of the subscription, or a developer bills for it, or you spend the hours. Nobody escapes it, and a build quote that excludes it is not a full quote.
3. Your own time
Usually the largest real cost and almost never counted. If the project takes three months of evenings, that is a genuine expense whatever the tools cost. It is also the cost most sensitive to a single decision: months spent building something nobody wanted is by far the most expensive outcome available, and it is the one this whole category makes easier to stumble into, because building has become fast enough that skipping validation feels rational.
What it costs to keep running
Year two onwards is usually cheaper than year one on tools and more expensive on everything proportional to success:
- ▸Tooling stays flat at roughly $250 to $600 a year unless you outgrow free tiers, which happens later than most people expect.
- ▸Infrastructure scales with usage, but gently. Most small SaaS products stay inside modest hosting and database tiers for a long time.
- ▸Payment processing scales exactly with revenue, at around 3%.
Where the money actually gets wasted
Three patterns account for most wasted spend, and none of them is a tool subscription.
- ▸Paid advertising before anything has converted. Advertising an offer that has never converted organically buys expensive confirmation of what a free test would have told you. Spend nothing on ads until something works without them.
- ▸Building beyond the first version. Every feature added before the first paying customer is a guess, and guesses are what you are trying to avoid paying for. Ship the smallest thing that solves one problem completely.
- ▸Buying scale early. Higher hosting tiers, premium plans and enterprise anything, bought for traffic that has not arrived. Free tiers carry a real product much further than their marketing implies.
The cheapest money in this entire exercise is what you spend finding out whether anyone wants the thing, before the build. It costs nothing but conversations, and it is the only spend that reliably prevents the large one.
Frequently asked questions
▸How much does it cost to build a SaaS in 2026?
For a solo founder building a first version, the realistic range is $250 to $650 for the whole first year using AI build tools, or $250 to $600 a year on a flat-fee AI venture platform. Hiring a developer or agency costs $5,000 to $50,000 for the initial build plus ongoing maintenance. These figures cover tools, hosting and a domain; they exclude paid advertising and your own time, which are usually the larger numbers.
▸Can you build a SaaS for free?
You can build one for close to free. Most AI build tools have genuine free tiers and most hosting platforms have a free plan that comfortably handles early traffic. The unavoidable costs are small: a domain at roughly $12 a year, and payment processing fees once you actually have revenue. What free tiers usually cost you is the tool's badge displayed on your application, with removal sold at the first paid tier. So a functional free build is realistic; a free build that looks like an independent business generally is not.
▸Is it cheaper to build a SaaS yourself or use a platform?
The monthly figures are close enough that cost is the wrong deciding factor: roughly $20 to $50 either way. What differs is scope. Doing it yourself, you handle market research, scoping, pricing, payment setup, launch and customer acquisition. A venture platform does more of that work, and the one thing to check carefully is whether it takes a share of revenue, because a 15-20% share will exceed any subscription many times over for a business that succeeds.
▸Why do developers cost $5,000 to $50,000 when AI tools cost $30?
You are buying different things. AI tools produce software from a specification and give you no guarantee about the result. A developer or agency takes responsibility for an outcome, handles the complexity that generic tools avoid, and can work inside regulatory requirements, legacy integrations and unusual architectures. For a straightforward self-serve product the AI route is now genuinely competitive. For anything with compliance obligations, deep integrations or an unusual specification, the price difference reflects a real difference in what you get.
▸What are the hidden costs of running a SaaS?
Three consistently get missed. Payment processing takes roughly 2.9% plus 30 cents per transaction and is charged from your first sale. Transactional email costs $0 to $20 a month and is not optional once you have users. And maintenance is continuous: dependencies, security updates and support do not stop, whether you pay a platform or your own hours.
▸How much should I budget before I have any customers?
Less than most people assume, and it should be almost entirely tools rather than advertising. A sensible first-90-days budget is $100 to $200 total: a domain, one build tool or platform subscription, and nothing else. Do not budget for paid advertising until something has already converted organically, because advertising an offer that has never converted for free reliably buys you expensive proof of what a free test would have shown.
