You can start a SaaS for under $100 a month in tooling if you build it yourself — hosting, a domain, email, and payments are cheap or free at low scale. The real costs are your time to build it and, later, customer acquisition. Outsourced development is where budgets balloon into the tens of thousands.

The actual cash to run an early-stage SaaS is low. A domain is roughly $10-15 a year. Hosting on modern platforms is free to a few dollars a month until you have real traffic. Payments via Stripe cost a per-transaction fee (around 2.9% + 30¢) with no monthly base. Transactional email, a help desk, and basic analytics all have free tiers. Most solo founders run on well under $100/month in tooling until they have paying customers.
Watch the subscription creep, though. It is easy to accumulate $50/month each across a dozen "essential" tools — email marketing, scheduling, design, CRM, analytics — and quietly reach $500/month before you have revenue. Resist this until something is actually constraining growth.
If you can code, building costs you time, not cash. If you cannot and you hire an agency or freelance developers, a basic SaaS MVP commonly runs from roughly $15,000 to $50,000+, and more for anything complex. This is where "starting a SaaS" stops being cheap.
AI app builders and AI coworkers have collapsed this. A non-technical founder can now get a working product surface and a real website without writing code or hiring out — turning a five-figure build into a free-to-low-cost one. The trade-off is that you stay closer to the product yourself, which early on is usually a good thing.
Building is no longer the bottleneck — distribution is. The cost that actually decides whether your SaaS survives is customer acquisition: ad spend, content, outreach time, and the months it takes to find a channel that works. Budget for this mentally even if it is mostly your time at first.
A sensible early plan: keep tooling under $100/month, validate with manual sales and personal outreach (near-zero cash), and only spend on paid acquisition once you have proof a message converts. Spending on ads before that is the most common way to burn a starting budget.
MadMantra removes the two biggest line items at once: it builds and hosts your website with payments wired in, and it runs the distribution — outreach, ads, content — that usually costs the most in time and money. It is free to start and the paid plans are $49 or $99/month, which replaces a stack of separate subscriptions and a developer you would otherwise hire.
Close to it, if you build it yourself. Free hosting tiers, a cheap domain, Stripe (which only charges per transaction), and free tools can get you live for a few dollars. The real investment is your time. The cost only rises when you outsource development or start paying for customer acquisition.
A basic MVP from an agency or freelancers typically ranges from about $15,000 to $50,000 or more, depending on complexity. This is the single largest startup cost for non-technical founders — and the one AI tools have most disrupted, since you can now get a working product without hiring out.
Early on, expect well under $100/month: hosting, domain renewal, email, and basic tools, plus Stripe's per-transaction fees. The bigger ongoing cost as you grow is customer acquisition — ad spend and the time or tools spent on marketing and outreach.
