# How Much Should a Startup Spend on Marketing? (Free Calculator)

Typical startup marketing budgets by stage as a share of burn, the people, programs and tools split, two worked examples and a free calculator to set yours.

# How Much Should a Startup Spend on Marketing? (Free Calculator)

Most early-stage startups spend somewhere between 10% and 25% of monthly burn on marketing, and that number climbs with stage. Pre-seed teams usually sit at 5% to 10% of burn, mostly founder time and tools. Seed teams land around 10% to 20%. Series A companies often run 20% to 35% once a repeatable channel shows up, and Series B can go higher. Treat these as typical ranges, not rules. The right number is the one you can tie to a specific goal, a specific channel and a kill date.

That's the short answer. The longer answer is that "how much" is the wrong first question. The better question is: what are you trying to learn or prove in the next 90 days, and what's the cheapest way to prove it?

I've watched a lot of launches across Web3, AI and security. The teams that burn money on marketing rarely overspend on a single line. They spread a modest budget across eight channels, learn nothing from any of them, and then decide "marketing doesn't work for us." The teams that win spend less, on fewer things, with sharper questions attached.

## Startup marketing budget by stage: typical ranges

This is roughly how budgets look across stages. The percentages are share of total monthly burn. The absolute ranges are rough monthly totals for a venture-backed software company, including people, programs and tools.

| Stage | Typical % of burn | Typical monthly marketing spend | What the money is mostly for |
|---|---|---|---|
| Pre-seed | 5% to 10% | $2K to $8K | Founder content, a website, a few tools, small tests |
| Seed | 10% to 20% | $8K to $40K | First marketer or contractors, content, 2 to 3 channel tests, launch PR |
| Series A | 20% to 35% | $40K to $150K | Small team, one or two scaled channels, events, brand |
| Series B | 25% to 40% | $150K to $500K+ | Full team, paid at scale, analyst relations, international |

A few honest caveats. B2B companies with enterprise sales often put more into sales than marketing, so their marketing share can look low on paper. Consumer apps can run much higher because paid acquisition is the growth engine. And Web3 projects in a pre-token phase often spend in bursts around launches rather than in a steady monthly line.

If your number sits outside these ranges, that isn't automatically wrong. It just needs a reason you can say out loud to your board.

## The three buckets: people, programs and tools

Every marketing budget splits into three buckets. Getting the ratio right matters more than the total.

- **People:** salaries, fractional operators, freelancers, agencies. This is usually 50% to 70% of the budget at seed and Series A.
- **Programs:** the money that actually goes out the door to reach someone. Paid ads, sponsorships, events, PR sprints, content production, swag, launch costs.
- **Tools:** CRM, email platform, analytics, design software, SEO tools, social scheduling. Usually 5% to 15% of the total.

The most common mistake I see is a seed team that hires a full-time marketer and then gives them almost no program budget. That person spends six months writing strategy decks because there's no money to run anything. If you're hiring, budget at least 30% to 40% of their loaded cost as program money, or they can't prove anything.

The opposite mistake is just as expensive: a big program budget with nobody senior enough to run it. $20K a month in paid social managed by an intern is a donation to Meta.

## Fixed vs variable marketing costs

Split every line into fixed or variable before you approve it.

**Fixed costs** don't move with results: salaries, retainers, tool subscriptions, your website. They're the floor you pay even in a bad month.

**Variable costs** scale up or down with performance: paid ads, affiliate payouts, referral rewards, per-event costs, usage-based tools.

A healthy early budget keeps fixed costs low enough that you could survive three months of zero results without cutting people. If more than 75% of your marketing spend is fixed at seed, you've locked yourself into a plan before you've learned what works.

Retainers sit in an awkward middle. A PR retainer is fixed for the term, but you can scope it to a 3-month window so it behaves more like a test. That's one reason I offer fractional work in 3-month minimums rather than year-long contracts.

## How to use the marketing budget calculator

I built a free [startup marketing budget calculator](/tools/marketing-budget-calculator) because founders kept asking me for a number and I kept giving the same answer: it depends on your stage, your burn and your goal. The tool makes that answer concrete.

You enter three things:

- Your stage (pre-seed through Series B)
- Your monthly burn, or a total marketing budget if you already have one
- Your main goal, such as pipeline, signups, awareness, fundraising support or a launch

It then splits the budget across channels, people and tools, estimates your customer acquisition cost and payback period, and lets you export the whole thing as a CSV. If you prefer spreadsheets, the same logic lives in the [marketing budget template](/resources/marketing-budget-template.xlsx).

Two worked examples show how this plays out in practice. Both are illustrations, not client data.

### Worked example 1: seed-stage B2B AI tool

Say you run an AI contract-review tool for mid-size law firms. You raised a $3M seed, your burn is $180K a month, and your goal for the next two quarters is qualified pipeline for a two-person sales team.

At 12% of burn, your marketing budget is about $21,600 a month. A sensible split:

| Line | Monthly amount | Bucket | Notes |
|---|---|---|---|
| Fractional content and demand lead | $8,000 | People | Owns the plan, writes or edits content |
| Design and video contractor | $2,000 | People | Landing pages, demo clips, case study layouts |
| LinkedIn ads test | $4,000 | Programs | Targeted at legal ops and GC titles |
| Legal-tech event sponsorship (amortized) | $3,000 | Programs | One regional event per quarter |
| Content production and webinars | $2,500 | Programs | Two webinars per quarter with a customer |
| Tools | $2,100 | Tools | CRM, email, analytics, enrichment |

Now check it against the goal. If a closed deal is worth $30K in first-year contract value and your sales team closes 20% of qualified opportunities, you need 5 qualified opportunities to win 1 deal. If your blended cost per qualified opportunity comes in at $2,000, the marketing cost per deal is $10,000. Against $30K in first-year value, that's a payback well under a year. Worth scaling.

If cost per qualified opportunity comes in at $6,000, the marketing cost per deal is $30,000 and payback stretches past a year before you count sales salaries. Cut the weakest channel and move money to the one producing opportunities.

### Worked example 2: pre-seed consumer AI app

Say you're building an AI study assistant for university students. You raised $750K, your burn is $45K a month, and the goal is 10,000 signups before you raise again.

At 10% of burn, you have $4,500 a month. That's not enough for a hire, so the founders do the work and the money goes almost entirely into programs:

| Line | Monthly amount | Bucket | Notes |
|---|---|---|---|
| Micro-creator partnerships | $2,000 | Programs | 4 to 8 student creators on TikTok and Shorts |
| Referral rewards | $800 | Programs | Paid only when a referred user activates |
| Paid social test | $1,000 | Programs | Retarget video viewers, test 3 hooks |
| Tools | $700 | Tools | Analytics, email, link tracking |

The math here is cost per activated user, not per signup. If you're paying $1.50 per signup but only 30% activate, your real cost is $5 per activated user. At 10,000 signups and 30% activation, that's 3,000 real users for roughly $15,000. That's a fundable story only if retention holds past week four.

## A simple formula for setting your number

If you want one formula to start from, use this:

```text
Monthly marketing budget = (Target new customers per month x Target CAC) + Fixed marketing costs
```

Target CAC should come from your unit economics, not your hopes. A common rule of thumb for SaaS is that you want to recover CAC within 12 to 18 months of gross margin. So:

```text
Max CAC = Monthly gross margin per customer x Target payback months
```

Example: a customer pays $1,000 a month at 80% gross margin. That's $800 a month in margin. With a 15-month payback target, your max CAC is $12,000. If you want 4 new customers a month, your variable marketing and sales spend should not exceed $48,000 a month, plus whatever fixed costs you carry.

If you need a deeper walkthrough of the payback math, I cover it in [CAC, LTV and payback period explained](/blog/cac-ltv-payback-period-explained).

## Where PR and launches fit in the budget

PR is usually a burst cost tied to a moment: a funding round, a product launch, a token generation event, a market entry. It doesn't need to be a permanent line at pre-seed.

The pattern that works for most seed teams is a 4 to 8 week launch sprint around one real piece of news, then a decision about whether to keep a smaller monthly retainer. For reference, my fractional retainers run $5K to $12K a month and launch sprints $15K to $40K total. Traditional AI PR agencies often charge $20K to $50K a month, which is a lot of a seed budget to commit before you know whether earned media moves your pipeline.

The rule I give founders: don't fund ongoing PR until you have a calendar with at least one real news moment every six to eight weeks. Without news, a retainer turns into a monthly status call.

## Common marketing budgeting mistakes

These show up again and again, at every stage.

- **Spreading thin.** Eight channels at $500 each teaches you nothing. Three channels at $1,500 each, with clear kill criteria, teaches you a lot.
- **No kill date.** Every test needs a date and a number. "We'll try LinkedIn ads" isn't a test. "We'll spend $3K on LinkedIn ads over 6 weeks and kill it if cost per demo is above $400" is.
- **Measuring the wrong thing.** Impressions and followers are easy to buy. Measure the step closest to revenue you can actually track.
- **Hiring before budgeting programs.** A marketer without a program budget is a strategist with no army.
- **Copying a later-stage company.** A Series C playbook with a seed budget produces a smaller, sadder Series C playbook.
- **Ignoring founder time.** At pre-seed and seed, founder hours are your largest marketing resource. Budget them like money.
- **Annual tool contracts too early.** Pay monthly until a tool has proven itself for a quarter.

## Your 30-minute budget checklist

Use this before you take a number to your co-founder or board.

- [ ] I know my monthly burn and the percentage going to marketing
- [ ] I've split the budget into people, programs and tools
- [ ] At least 30% of the total is program money I can actually spend
- [ ] Fixed costs are under 75% of total marketing spend
- [ ] Every channel test has a budget, a duration and a kill number
- [ ] I know my target CAC and payback period
- [ ] PR spend is tied to a specific news moment, not an open-ended retainer
- [ ] I've run my numbers through the [budget calculator](/tools/marketing-budget-calculator) or the template
- [ ] Someone senior owns the budget and reports on it monthly

If you want the line-by-line version for a seed company, I break every item down in the [seed-stage marketing budget template](/blog/seed-stage-marketing-budget-template).

The right budget isn't the biggest one you can defend. It's the smallest one that can answer your most expensive open question.
