Best Free SaaS Unit-Economics Calculators 2026
Best free SaaS unit-economics calculators 2026: no-signup what-if tools for unit economics, pricing, and valuation, vs the paid SaaS dashboards.
The best free SaaS unit-economics calculators in 2026 are the ones that let you model a scenario with no signup and no billing connection. Three on this hub cover the core questions: the Solo Founder Unit Economics calculator (LTV, CAC, payback, break-even), the Micro-SaaS Pricing Engine (what to charge), and the Business Valuation Calculator (a multiple-based valuation range). Each example below is computed live from the shipped engine, not typed by hand.
The honest distinction: these are what-if calculators, not analytics dashboards. ProfitWell Metrics (free)[1], ChartMogul (free under $10K MRR)[2], and Baremetrics (from $129/mo)[3] connect to your Stripe or Paddle account to report actuals. The calculators run on numbers you type, so you can use them before you have a single customer. Pick a calculator to model; pick a dashboard to measure.
Search for a "free SaaS calculator" and you land on two very different kinds of product wearing the same words. One is a what-if calculator: type assumptions, get a number, no account. The other is a subscription-analytics dashboard: connect your billing system, see your real metrics. Both are useful, for opposite jobs. This roundup picks the best free what-if calculators for the three questions a SaaS founder asks most — unit economics, price, and valuation — shows each one running live, and draws the honest line between them and the paid dashboards.
1. Calculator vs dashboard: two different jobs
The most common mistake when shopping for a "free SaaS metrics tool" is comparing a calculator to a dashboard as if they competed. They do not:
- A what-if calculator takes assumptions you type — price, churn, CAC, ARPU — and returns the implied metrics instantly. No account, no billing connection. It answers "what would happen if..." and works before you have any customers.
- An analytics dashboard connects to your payment processor (Stripe, Chargebee, Paddle) and reports your actual MRR, churn, and LTV from live data. It answers "what is actually happening" and requires real paying customers to be useful.
The three tools featured below are calculators, chosen because the converting search intent — "free SaaS calculator" — is overwhelmingly people who want to model a number now, not connect their billing. Each example is rendered live from the shipped engine at build time, so the inputs and outputs you see are real engine output, never hand-typed.
2. Free unit-economics calculator
The Solo Founder Unit Economics calculator takes six inputs — MRR, paying customers, monthly churn rate, CAC, ARPU, and monthly fixed costs — and returns LTV, the LTV:CAC ratio, CAC payback in months, customer lifetime, monthly profit per customer, break-even customer count, and total monthly profit. It is the fastest way to sanity-check whether a SaaS is economically sound. A worked run:

| mrr | 8000 |
|---|---|
| paying_customers | 160 |
| monthly_churn_rate | 4 |
| cac | 120 |
| arpu | 50 |
| monthly_fixed_costs | 1500 |
| arpu | 50 |
|---|---|
| ltv | 1250 |
| cac | 120 |
| ltv cac ratio | 10.4 |
| payback months | 2.4 |
| customer lifetime months | 25 |
| monthly profit per customer | 50 |
| break even customers | 30 |
| total monthly profit | 6500 |
| insight | Healthy unit economics: $1250 LTV on $120 CAC (10.4x), 25-month customer lifetime. At 160 customers you net $6500/mo after fixed costs. |
Computed live at build time.
The engine returns the full unit-economics picture from those six typed numbers, including the LTV:CAC ratio and payback months that decide whether acquisition is sustainable. Because it needs no billing connection, you can run it on a pre-launch plan to see whether the numbers work before spending a dollar on acquisition. The method behind it is laid out in solo founder unit economics after six months, and the common pre-seed traps in the unit-economics lies pre-seed founders tell.
3. Free micro-SaaS pricing engine
The Micro-SaaS Pricing Engine answers the next question: what should you charge? It takes current users, API cost per user, fixed monthly costs, a competitor price range, and a target gross margin, and returns a price recommendation grounded in both cost-plus and competitive anchoring. A worked run:
Show the recompute-verified inputs and outputs
| current_users | 200 |
|---|---|
| api_cost_per_user | 0.8 |
| fixed_monthly_costs | 1200 |
| competitor_price_low | 15 |
| competitor_price_high | 60 |
| target_gross_margin | 85 |
| price floor | 45.33 |
|---|---|
| suggested price | 45.33 |
| price ceiling | 72 |
| cost per user | 6.8 |
| total monthly cost | 1360 |
| price points › row 1 › price | 45.33 |
| price points › row 1 › mrr | 9066 |
| price points › row 1 › gross margin | 85 |
| price points › row 2 › price | 45.33 |
| price points › row 2 › mrr | 9066 |
| price points › row 2 › gross margin | 85 |
| price points › row 3 › price | 72 |
| price points › row 3 › mrr | 14400 |
| price points › row 3 › gross margin | 90.6 |
| insight | At 200 users and $45.33/mo, your projected MRR is $9066. The suggested price gives you 85% gross margin with room to grow. |
| margin warning | false |
Computed live at build time.
The engine renders a recommended price and the margin math behind it from the typed inputs. It is the model-a-price counterpart to a dashboard, which can only tell you what your current price is already earning. The reasoning behind tier-based pricing is in the micro-SaaS pricing engine at $19 vs $29 vs $49, and how it relates to the seat-versus-usage choice in the pricing model picker vs the micro-SaaS engine.
4. Free business-valuation calculator
The Business Valuation Calculator answers the exit question. It takes annual revenue and a revenue multiple, SDE and an SDE multiple, and EBITDA and an EBITDA multiple, then returns each method's range plus a blended valuation range and warnings when the inputs look inconsistent. A worked run:

| blended range › mid | 530000 |
| blended range › high | 648000 |
Computed live at build time.
The engine returns each valuation method side by side and a blended range, computed live from the typed inputs. This is the free, no-signup way to get a defensible valuation band before a broker conversation; the seller's-eye method is in valuation by revenue vs SDE vs EBITDA for a solo business, and a full walk-through in a one-person SaaS valuation and acquisition walk.
5. Honest comparison to the paid dashboards
The named alternatives most people find searching for SaaS metrics are analytics dashboards, not calculators. Verified positioning as of May 25, 2026:
| Tool | Type | Pricing | Needs billing connection? |
|---|---|---|---|
| ProfitWell Metrics (Paddle)[1] | Analytics dashboard | Free | Yes (Stripe/Chargebee/Paddle) |
| ChartMogul[2] | Analytics dashboard | Free under $10K MRR, then paid by MRR | Yes |
| Baremetrics[3][4] | Analytics dashboard | Paid from $129/mo | Yes |
| This hub's three calculators | What-if calculators | Free, no signup | No |
Read this honestly: if you already have paying customers and want to track your real MRR, churn, and LTV, ProfitWell Metrics is a genuinely free, capable dashboard, and ChartMogul or Baremetrics add depth as you scale. None of those is what the free calculators replace. The calculators win when you want to model a scenario — a launch price, a valuation band, a pre-launch unit-economics check — without connecting a billing system you may not even have yet. They are complements, not substitutes: model with a calculator, measure with a dashboard.
One thing the calculators do that a dashboard cannot: run on numbers that do not exist yet. A dashboard can only report customers you already have. If your question is "what price clears 85% margin" or "what would this be worth at a 3x revenue multiple," only a what-if calculator answers it.
6. Which free tool for which question
- "Are my unit economics sound?" → Solo Founder Unit Economics (LTV, CAC, payback, break-even).
- "What should I charge?" → Micro-SaaS Pricing Engine (cost-plus + competitive anchoring).
- "What is my business worth?" → Business Valuation Calculator (revenue, SDE, EBITDA multiples).
- "What are my actual live metrics?" → a paid/free analytics dashboard (ProfitWell Metrics free, ChartMogul, Baremetrics) — connect your billing system.
Re-verify the dashboards' pricing before committing; analytics-tool tiers change with MRR bands. For the calculators, nothing to re-verify: they are free, need no signup, and compute from numbers you type.

Frequently asked questions
What is the best free SaaS unit-economics calculator in 2026?
For what-if math with no signup, the three free standalone calculators on aibizhub cover the core questions: the Solo Founder Unit Economics calculator for LTV, CAC, payback, and break-even; the Micro-SaaS Pricing Engine for setting a price; and the Business Valuation Calculator for a multiple-based valuation range. They take typed assumptions and return numbers instantly without connecting your billing system. The paid dashboards (ProfitWell Metrics, ChartMogul, Baremetrics) solve a different job: they read your live billing data to report actuals. The right pick depends on whether you want to model a hypothetical or measure reality.
Are these free calculators the same as ProfitWell or Baremetrics?
No, and that is the point. ProfitWell Metrics (free), ChartMogul (free under $10K MRR, then paid), and Baremetrics (paid from $129/month) are subscription-analytics dashboards: you connect Stripe, Chargebee, or Paddle and they report your actual MRR, churn, and LTV from live data. The free aibizhub calculators are what-if tools: you type assumptions and get outputs with no billing connection and no signup. Use a calculator to model a price, a valuation, or a pre-launch unit-economics scenario; use a dashboard to track the real numbers once you have paying customers.
Do I have to connect my Stripe account to use these calculators?
No. All three free calculators run entirely on numbers you type — no account, no billing integration, no data leaves the page in order to compute. That is the structural difference from the analytics dashboards, which require connecting your payment processor to function. It also means you can use the calculators before you have any customers at all, to model a launch price or a pre-launch unit-economics scenario.
Which free SaaS calculator should I use to check unit economics before I have any paying customers?
Use the Solo Founder Unit Economics calculator, because it runs entirely on assumptions you type with no billing connection, so it works pre-launch when you have zero customers. You enter MRR, paying customers, monthly churn rate, CAC, ARPU, and monthly fixed costs, and it returns LTV, the LTV-to-CAC ratio, CAC payback in months, customer lifetime, profit per customer, break-even customer count, and total monthly profit. The paid analytics dashboards (ProfitWell Metrics, ChartMogul, Baremetrics) cannot help here at all, because they only report actuals from a connected payment processor and need real paying customers to function. Model the scenario with the free calculator first; connect a dashboard later, once you have live revenue to measure.
What is the best free no-signup tool to model a SaaS price or a valuation band before talking to a broker?
For setting a price, use the free Micro-SaaS Pricing Engine: it takes current users, API cost per user, fixed monthly costs, a competitor price range, and a target gross margin, and returns a price recommendation grounded in both cost-plus and competitive anchoring, with no signup. For a valuation band, use the free Business Valuation Calculator: it takes annual revenue with a revenue multiple, SDE with an SDE multiple, and EBITDA with an EBITDA multiple, then returns each method's range plus a blended valuation range. Both compute from typed inputs only and need no billing connection, so you can produce a defensible price or valuation band before any broker conversation. A dashboard cannot answer either question, because it can only report numbers you already have, not model the ones you are deciding.
