Your Runway Is Lying to You

Most founders calculate runway the same way:

Cash in the bank ÷ monthly burn = months left.

It’s clean. It’s simple. It’s usually wrong.

Not because you can’t divide.

Because that formula ignores the real structure of your company.

And in Canada, especially if you’re VC-backed and building technology, it often ignores hundreds of thousands of dollars already sitting in your business.

The Simple Formula (And Why It Fails)

Let’s say:

You raised a $1.8M seed round.

You’re burning $225K per month.

You have $1.35M left in the bank.

On paper:

$1.35M ÷ $225K = 6 months of runway.

That’s what you tell your board.

But here’s what that calculation ignores.

Burn Is Not the Same as Expense

Your income statement might show:

• $160K in engineering salaries

• $30K in marketing

• $20K in G&A

• $15K in SaaS tools

Total: $225K.

But your real cash burn could be:

• Higher (if you prepaid annual SaaS, hardware, insurance)

• Lower (if some costs were capitalized)

• Distorted (if you received deferred revenue or grants)

Founders often mix:

• Accounting loss

• Cash burn

• Committed contractual burn

They are not the same. And small differences matter when you only have 6 months left.

The Hidden Line Item Most Founders Ignore

Now here’s where it gets interesting.

Let’s assume:

• Of that $160K monthly engineering spend, $140K qualifies as eligible R&D.

• Over 12 months, that’s roughly:

• $1.68M in eligible technical salaries.

If you’re a Canadian-controlled private corporation (CCPC) in Ontario or Quebec, under the enhanced thresholds, that can translate into:

Roughly 30%–45% combined federal + provincial refundable credits (depending on province, structure, assistance, and thresholds).

Conservatively:

Let’s assume $500K in total SR&ED-related refundable credits, which is earned non-dilutive capital. But it doesn’t show up in your bank account yet.

It shows up as a receivable if it’s filed properly.

Why This Changes Everything

If your base runway is 6 months…

But you’re entitled to ~$500K in refundable tax credits…

That could represent 2 additional months of runway at your current burn.

Two months can mean:

• Delaying a raise

• Negotiating from strength

• Avoiding a down round

• Hitting a product milestone before your next pitch

In venture terms, that’s leverage.

The Dangerous Mistake

There are two ways founders get this wrong.

Mistake 1: Ignoring SR&ED entirely

They raise earlier than necessary. 

They dilute more than necessary. 

They leave non-dilutive capital on the table.

Mistake 2: Overestimating it

They assume:

• Everything qualifies

• The refund arrives immediately

• There’s no review risk

• There are no phase-outs

Then the claim gets reduced. Or processed slower. Or partially denied.

Now runway compresses overnight.

That’s how liquidity crises happen.

Timing Matters More Than Amount

Even if you’re entitled to $500K…

You still have to consider:

• When your taxation year ends

• When you file

• CRA processing timelines

• Review likelihood

• Whether you crossed enhanced thresholds

• Whether provincial credits reduce your federal base

SR&ED is not instant cash. It’s structured working capital.

And working capital needs forecasting.

Ontario vs Quebec: Why Province Matters

If you’re in Ontario, refundable provincial credits layer differently than in Quebec.

If you’re in Quebec, the ecosystem is heavily R&D-driven and often interacts with other grants and incentives.

The structure of your credits can materially change:

• Cash timing

• Refundability

• Net benefit

That’s why provincial modeling matters before you build it into your runway assumptions.

A Smarter Way to Model Runway

Instead of:

Cash ÷ burn = runway

Model three scenarios:

1️⃣ Base runway (no credits included)

2️⃣ Adjusted runway (credits modeled conservatively)

3️⃣ Stress-case runway (refund delayed or partially reduced)

That’s how you plan like a CFO.

Final Thought

SR&ED isn’t “free money.”

It’s non-dilutive capital tied directly to your technical execution.

If you’re VC-backed and building in Canada, your runway model should include tax credit forecasting, but only if it’s defensible and timed correctly.

Because in a venture, two months of runway can change everything.
