How to Calculate Your SaaS 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.
