An in-house US team building a first SaaS release in 14 weeks spends about $148,000 on loaded labor alone, based on federal wage data. A production-ready version one adds roughly $412,000 more. Those numbers surprise founders who budgeted from a single quote. Plan for them.
SaaS development cost is the total spent to build and launch a subscription software product, plus the cost of running it once customers arrive. Labor drives most of it. Architecture choices, such as how tenants share infrastructure, decide much of the rest.
This guide shows the full math for three budget tiers, so you can swap in your own rates. It then walks through the scope and architecture decisions that move SaaS development cost up or down.
The cost to build a SaaS product with an in-house US team runs from about $148,000 for a 14-week MVP to $412,000 for a six-month version one. A full scale-up year, with five developers, a designer and two testers working through the product’s second year, costs around $1.45 million. Team size and duration explain the range. The table shows the hours behind each figure.
Rates come from the Bureau of Labor Statistics. In May 2025 the median software developer earned $135,980 a year, and QA analysts and testers earned $104,300. Web and digital interface designers earned a median of $104,000. Wages were 68.5% of employer costs for full-time private industry workers in June 2026, according to the BLS compensation release. That gives loaded rates of about $95 an hour for developers and $73 for designers and testers.
| Tier | Length | Team | Loaded labor cost |
| MVP | 14 weeks | 2 developers, half-time designer, half-time QA | About $148,000 |
| Version one | 6 months | 3 developers, half-time designer, 1 QA | About $412,000 |
| Scale-up year | 12 months | 5 developers, 1 designer, 2 QA | About $1.45 million |
Your own product owner’s time sits outside these totals, and so do cloud bills and any compliance audit. Median wages also understate pay in high-cost metro areas, so treat the table as the floor for SaaS development cost with an in-house team.
Partner quotes, onshore or offshore, should be compared against these totals on the same scope. The project estimator on our site gives a first range in a few minutes.
A SaaS MVP should include only what a paying customer needs to get the core job done, plus the minimum for sign-up and payment. Everything else waits for evidence. Keeping that line strict is the single biggest lever on SaaS MVP cost, because each extra module adds weeks of build and testing.
| Build in the MVP | Leave for later |
| Core workflow for one user role | Extra roles and fine-grained permissions |
| Email sign-up, password reset, multi-factor login | Single sign-on with SAML |
| One plan with card billing | Usage-based pricing, invoicing, coupons |
| Basic admin to manage accounts | Self-serve analytics dashboards |
| Error tracking and backups | Multi-region failover |
| 1 or 2 integrations customers ask for first | Public API and marketplace |
Founders often want single sign-on in the first release because one large prospect asked for it. Treat that as a paid add-on for that one deal, priced and scheduled on its own, so the rest of the release still ships on time for everyone else. It can add several weeks of work on its own.
The guide to MVP development covers how to choose the core workflow and test it with early users. Read it before scoping.

Multi-tenancy changes the SaaS development cost through the isolation model you choose. Pooled tenants share databases with row-level separation, which costs least to build and run. Dedicated resources per tenant, the silo approach, cost most, and the bridge model mixes the two, often per service.
AWS describes these three patterns in its SaaS Lens guidance. Its multi-tenant guidance notes that the silo model gives the strongest isolation at the highest cost and complexity.
| Model | How tenants are separated | Build effort | Running cost | Fits |
| Pool | Shared database, tenant ID on every row | Lowest | Lowest | SMB customers, high volume |
| Bridge | Shared app, separate schema or database per tenant | Medium | Medium | Mid-market, some data rules |
| Silo | Dedicated stack per tenant | Highest | Highest | Enterprise or regulated buyers |
Start pooled unless contracts or regulations demand more. Design the tenant ID into every table and every query from day one. Then test it. Adding it later is one of the costliest rewrites a SaaS team can face. Retrofits hurt.
We cover the trade-offs in more depth in multi-tenant SaaS architecture.
Billing and security, with the first integrations, often take a quarter to a third of an MVP’s engineering time. None of it is optional. Subscription logic covers plans, trials and failed payments. Security work covers login controls and audit logs, and every integration needs upkeep as the other system changes.
Payments. Buy before you build. Stripe lists Billing at 0.7% of billing volume on top of payment processing. At $50,000 in monthly recurring revenue, that is $350 a month, far less than a developer’s time spent on proration and dunning logic.
Security. Budget for multi-factor login, role-based access, encryption at rest and in transit, and audit logs in the MVP. Plan a penetration test against the OWASP Top 10 before the first enterprise sale. Mid-market and enterprise buyers usually ask for a SOC 2 Type II report, which takes months of evidence collection. Start early.
Integrations. Each takes one to three weeks. The other system’s API sets the pace. Customers will ask for many. Ship the 1 or 2 that block the most deals, then add others against signed demand. Say no often.
Running a SaaS product costs cloud hosting and third-party services every month, plus support and maintenance, and maintenance is usually the largest line. Assume engineering upkeep of roughly 15% to 20% of the original SaaS development cost each year, then adjust with real data after six months.
| Running cost | What drives it | How to keep it down |
| Cloud hosting | Users, data volume, tenancy model | Right-size instances, pooled tenancy |
| Billing and payments | Revenue processed | Buy, then review fees yearly |
| Monitoring, email, error tracking | Users and event volume | Tiered plans, sampling |
| Maintenance engineering | Bugs, security patches, dependency updates | Automated tests, scheduled upgrades |
| Compliance | SOC 2 audits, penetration tests | Collect evidence continuously |
Cloud bills creep as usage grows, especially when test environments, old snapshots and oversized databases keep running long after the launch rush ends. The post on cloud cost optimization covers the checks that keep hosting in line with revenue.
The features that drive SaaS development cost most are permissions with many roles, real-time collaboration, usage-based billing, offline or mobile apps, and AI features with their own data pipelines. Each adds weeks of build and a long tail of testing. Simple CRUD screens rarely move the budget much.
| Feature | Typical added build time | Why it costs more |
| Fine-grained roles and permissions | 3 to 6 weeks | Every screen and API needs checks |
| Real-time collaboration | 6 to 10 weeks | Sync, conflicts, presence |
| Usage-based billing | 3 to 5 weeks | Metering, accuracy, disputes |
| Native mobile apps | 10 to 16 weeks | Second and third codebases |
| AI features | 4 to 12 weeks | Data pipeline, evaluation, cost per call |
These ranges assume a team that has built similar features before, and they feed straight into SaaS development cost. A first attempt usually takes longer.
Pricing decisions affect the build as well. Usage-based plans need metering that per-seat plans skip, so settle the model early with our guide to SaaS pricing models. For a team that has shipped multi-tenant products before, see our SaaS application development services.

For an in-house US team, a 14-week build with two developers plus part-time design and QA costs about $148,000 in loaded labor, based on May 2025 BLS wages. Cloud bills and your own product time come on top. Smaller scopes can come in under $100,000.
Expect 12 to 16 weeks for a focused SaaS MVP with one core workflow, card billing and basic admin. Single sign-on or native mobile apps each add several weeks, and a team building either for the first time should plan a buffer of two to three weeks. A clear scope signed off in week one keeps the date realistic.
Cut the first release to one user role and one core workflow. Buy billing and authentication services. Start with pooled multi-tenancy, and delay native mobile apps until web usage proves demand. Those four moves can remove whole modules from the first SaaS development cost estimate.
Yes. Building controls such as access reviews and change management takes engineering time, and the audit itself is a separate fee. Enterprise buyers often ask for a SOC 2 Type II report, which covers a review period of several months, so start collecting evidence early.
Budget for hosting and third-party services first. As a planning assumption, set engineering upkeep at 15% to 20% of the original build cost each year. Add billing fees, such as Stripe Billing at 0.7% of billing volume, and yearly security testing.
