CAC Calculator
Sales + marketing spend in a slice ÷ newly acquired customers counted the same window.
Open calculator →SaaS Subscription Cost Calculator
Total license spend from monthly price × seats × months—good for budgeting, not capitalization.
Overview
Stack software invoices before approving headcount-heavy seat growth. Taxes, FX, proration bumps, or canceled seats still drift from plain multiplication.
When to use this calculator
- Before renewing a stack of seats across several tools
- When you quote a client on “tools included” and need a clean monthly envelope
- When headcount changes and you want total license cost for the next few months
- When you compare two vendors and need an apples-to-apples month × seat model
Rule of thumb
This is a straight license roll-up—tax, true-ups, FX, and contract ramps can drift from the spreadsheet answer.

How to interpret this result
Total cash-style spend for licenses across users and months—good for budget envelopes.
It excludes discounting to present value and taxes unless you bake them into the monthly price.
True-up and annual prepay can make realized cash differ from this simple product.
Common mistakes
- Forgetting proration and true-up charges common with seat growth.
- Counting paused or free trials as paid seats.
- Extending months without aligning renewal dates.
What to do next
Runway or net-profit snapshots help if software spend is a big share of burn.
How to improve this result
- Turn off seats you have not touched in 60 days before buying more.
- Push annual prepay only when adoption is stable—otherwise you trade cash for unused months.
- Track price bumps from true-ups so “per month” math matches invoices.
Recommended tools
- Baremetrics SaaS metrics and subscription analytics dashboards.
- ChartMogul Subscription analytics for revenue, churn, and cohort reporting.
- ConvertKit Creator-focused email marketing and audience growth tools.
- MailerLite Email marketing for newsletters, automations, and simple landing pages.
FAQ
- Should this include VAT or GST?
- Only if you deliberately typed tax-inclusive pricing.
- Do annual prepay discounts belong here?
- Convert to an effective monthly price first, then multiply by months covered.
- Why might real invoices differ?
- True-ups when seats spike mid-month and partial refunds rarely sit in spreadsheet skeletons.
- Is usage-based spend included?
- Not unless you fold variable usage back into "monthly price" as an average.
- Can agencies use this?
- Yes—for client-visible stack costs—as long as you label it planning math, not client billing audits.
