How to calculate your SaaS budget
Practical guide to calculating your monthly software costs, finding cheaper alternatives, and optimizing your SaaS stack budget.
Who This Guide Is For
This guide is for:
- Founders trying to understand where their software budget is going
- Early-stage startups building their first tech stack
- Freelancers tracking tool costs for tax purposes
- Anyone who suspects they're overpaying for software
If you already know your tools and want to see total costs immediately, try the Budget Calculator — select your tools and see monthly totals with cheaper alternatives.
Why SaaS Costs Sneak Up on You
Software costs behave differently from other business expenses:
- Per-seat pricing scales — A $10/seat tool costs $120/year for one person, but $1,200/year for a team of ten
- Free trials turn into paid plans — Easy to forget about a trial until it converts
- Abandoned tools still bill — Services you stopped using months ago may still be charging
- Hidden fees add up — Premium integrations, overage charges, add-on features
Step 1: List Every Tool You Use
Before calculating costs, you need a complete inventory. Include:
- Active tools — What you use daily or weekly
- Occasional tools — Monthly or quarterly use
- Forgotten subscriptions — Check bank statements and credit card charges
- Free tiers — Note them too; they may have upgrade paths
Most startups use 10-30 SaaS tools. The budget calculator offers 97+ tools in its database to help you build a complete picture.
Step 2: Calculate True Monthly Cost
For each tool, determine:
| Factor | How to calculate |
|---|---|
| Base subscription | Monthly or annual fee |
| Per-seat cost | Cost × number of users |
| Add-ons | Premium features, extra storage, API calls |
| Annual vs monthly | Annual plans often save 15-20% |
Common pricing models
| Model | Example | True cost for team of 5 |
|---|---|---|
| Flat monthly | $50/month | $50 |
| Per-seat | $10/seat/month | $50 |
| Usage-based | $0.10 per API call | Varies |
| Tiered | $100 for up to 10 users | $100 |
| Freemium | Free basic, $20 for pro | $20 (if anyone needs pro) |
Step 3: Identify Cost Reduction Opportunities
Three ways to reduce SaaS costs:
1. Consolidate tools doing the same thing
If two tools overlap in functionality, you can often eliminate one. Common overlaps:
| Category | Common overlap |
|---|---|
| Analytics | Using both product analytics and web analytics when one covers both |
| Scheduling | Multiple scheduling tools for different teams |
| Writing | Both a grammar checker and an AI writing tool when one can handle both |
2. Switch to free or cheaper alternatives
Many software categories have free or lower-cost options. The Alternative Finder lets you search alternatives by price and free plan availability.
3. Right-size your plans
You may be on a plan that exceeds your needs:
- Are you actually using all the features on your current plan?
- Could some team members be on a lower tier?
- Are you paying for enterprise features you don't need?
Step 4: Calculate Stack Savings
For each tool, check if a cheaper alternative exists:
| Current tool | Monthly cost | Alternative | Monthly cost | Annual savings |
|---|---|---|---|---|
| Tool A | $50 | Tool B (free plan) | $0 | $600 |
| Tool C | $30 | Tool D | $15 | $180 |
| Tool E | $25 | Tool F (one-time) | $0 after year 1 | $300 |

Common Mistakes to Avoid
Mistake 1: Ignoring Stack Growth Over Time
The problem: Adding tools one at a time without reviewing total monthly spend.
The fix: Run a complete cost analysis every quarter. Review what you're actually paying versus what you need.
Mistake 2: Keeping Tools You Don't Use
The problem: A tool you used for one project six months ago is still billing you.
The fix: Audit your connected accounts and cancel tools you haven't used in 30 days.
Mistake 3: Free Plan Limits Costing More Than Paid Plans
The problem: Free plans with restrictive limits force inefficient workflows that cost more in time than a paid plan would.
The fix: Calculate the time cost of free tier limitations. Sometimes paying $20/month saves 5+ hours of workarounds.
Mistake 4: Overlooking Annual Plan Discounts
The problem: Monthly billing is convenient but often 15-20% more expensive than annual.
The fix: For tools you'll use for at least a year, annual billing saves money. For experimental tools, monthly is fine.
Frequently Asked Questions
How much should a startup spend on SaaS?
Most startups spend $50-200 per employee per month on SaaS tools. Early-stage companies with 1-5 people typically spend $200-800/month total. The right amount depends on your industry — a SaaS company needs more tools than a consulting business.
What's the average SaaS spend per employee?
According to industry data, the average SaaS spend per employee is around $100-150/month. However, this varies significantly by role — sales teams typically have higher tool costs than operations teams.
How often should I review my SaaS budget?
Quarterly reviews are a good cadence. Monthly is better for tracking growth, but quarterly gives you enough data to spot trends and take action. Set a recurring calendar reminder to review.
Should I use annual billing or monthly?
Annual billing saves 15-20% for tools you're committed to. Use monthly billing for experimental tools or when you're still evaluating. A hybrid approach works well — annual for core tools, monthly for everything else.
