Open calculator →Why we built free marketing calculators
Good marketing decisions come down to a handful of numbers — return on investment, return on ad spend, customer acquisition cost, lifetime value, and engagement. The problem is that those numbers usually live in scattered spreadsheets, behind a login, or inside an agency deck you only see once a quarter. These calculators pull each one into the open: a single-purpose tool that runs instantly in your browser, shows its formula, and explains what a healthy result looks like, so you can pressure-test a decision in seconds rather than days.
Every calculator computes only on the numbers you type in. There is no sign-up, no email wall, and — importantly — no fabricated benchmark data padding the output. Where general guidance exists (a common LTV:CAC target, a typical break-even relationship), we say so plainly and explain the reasoning; where a number genuinely depends on your market, margin, and execution, we tell you that too. The goal is a tool you can trust to do honest math, not one that flatters a channel to sell you something.
Which calculator solves which problem
Each tool answers a distinct question. Here's how they map to the decisions marketers and founders actually face.
Modeling growth impact — the ROI calculator
Multiplies traffic, conversion rate, and average deal value to show the revenue your funnel produces and the compounding uplift from improving each input. Use it to decide whether the next win is more traffic, a better-converting page, or a bigger deal size — the three levers rarely deserve equal effort.
Checking paid profitability — the ROAS calculator
Turns ad revenue and spend into return on ad spend, then compares it to your break-even ROAS so you can see whether a campaign is genuinely profitable or just busy. A 4x ROAS is a win at a 60% margin and a loss at a 20% margin — this tool makes that difference obvious.
Testing unit economics — the CAC & LTV calculator
Computes customer acquisition cost, lifetime value, the LTV:CAC ratio, and CAC payback period — the numbers that decide whether growth builds value or burns cash. It's the tool to reach for before scaling spend, because it tells you whether each acquisition dollar returns more than a dollar of lifetime profit.
Vetting and pricing creators — the engagement-rate and influencer-rate calculators
The engagement-rate calculator reveals whether an audience is real and active — the fastest authenticity check in influencer marketing — while the influencer-rate calculator turns followers, platform, and engagement into a transparent, disclosed pricing anchor for negotiation. Together they help you pay for genuine influence, not inflated reach.
How the numbers fit together
These metrics aren't independent — they form a chain. Traffic and conversion feed ROI; ad spend and margin feed ROAS; the customers you win feed CAC and LTV; and the creators you pay influence all of the above. A campaign can post a strong ROAS while quietly failing on LTV:CAC, or generate impressive engagement that never shows up as revenue. Reading the numbers together, rather than in isolation, is what stops a channel from looking healthy in one dashboard while draining the business in another.
That's also why we tie every metric back to a real growth decision. Use the calculators to find where your leverage is — often a conversion-rate fix is cheaper than more traffic, a margin-aware ROAS target beats a generic one, and a lower churn rate does more for LTV than any acquisition tactic. If you'd rather have the numbers moved for you, Gigde runs SEO and Generative Engine Optimization, content, paid media, social, and lead generation as done-for-you services measured on revenue, not vanity metrics.

Free tools FAQs
Are Gigde's marketing calculators free?
Yes. Every calculator is completely free, runs in your browser, and needs no sign-up or email. They compute on the numbers you enter — there is no fabricated data.
What can I calculate with these tools?
Marketing ROI, social media engagement rate, return on ad spend (ROAS) with break-even, customer unit economics (CAC, LTV, LTV:CAC ratio, and payback period), and estimated influencer post rates. Each tool also explains the formula and what a healthy number looks like.
How accurate are the results?
The math is exact for the inputs you provide. Real-world outcomes depend on your market, offer, and execution, so treat the projections as directional. For a forecast tailored to your funnel, request a free growth plan.
Do these calculators store or send my data?
No. Every tool runs entirely in your browser and computes only on the numbers you type in — nothing is uploaded, stored, or shared, and there is no sign-up or email wall. You can use them freely to model private financials without handing over any information.
Which calculator should I start with?
It depends on the question you're answering. Use the ROI calculator to model the revenue impact of growth, the ROAS calculator to check whether paid campaigns are actually profitable, the CAC & LTV calculator to test whether your unit economics are sustainable, and the engagement-rate or influencer-rate calculators to vet and price creators. Most teams end up using several together.
Can these tools replace a proper financial model?
They're a fast, honest starting point, not a full financial model. Each calculator isolates one metric so you can pressure-test a decision quickly, but real forecasts layer in seasonality, cohorts, and channel interactions. Use the calculators to find where the leverage is, then build a fuller model — or ask us for a tailored growth plan.
