Funding a marketing push when your ads already work

Ad platforms are brilliant at one thing: taking your money fast. When your campaigns are working, the frustrating part isn’t the ads — it’s that you can’t afford to spend more of them before the revenue catches up. Funding a marketing push is about letting a proven engine run at full speed rather than idling while your bank balance recovers.

The important word there is proven.

When does borrowing for marketing make sense?

Here’s a simple test. Answer yes or no:

1. Do you know your return on ad spend (ROAS) or cost per acquisition for at least the last two or three months?
2. Do you know your gross margin after product cost, shipping, payment fees and discounts?
3. Does your ROAS sit comfortably above break-even at that margin?
4. Could you handle a month where results come in 30% lower than expected?

Four yeses: funding a push is a reasonable growth move. Two or fewer: spend a bit more time tightening your numbers first. Our guide to unit economics before you borrow for ads walks through each of these.

Run the numbers

Use the calculator below to sanity-check a campaign. Plug in your planned budget, a realistic ROAS (not your best week) and your gross margin. The key figure is the break-even ROAS: the point where gross profit exactly pays back the ad spend. Anything above it is contribution toward overheads and profit; anything below it is a loss funded by the loan.

What kinds of marketing do NZ businesses fund?

Two lanes to fund the push

Unsecured funding or a line of credit — for businesses trading around six months or more, sized off turnover and bank statements. Some decisions come back the same day, and weaker credit is considered. A line of credit is particularly useful for ad spend because budgets flex week to week.

Property-secured loan — from $20,000 to $1m secured against NZ property you or a supporting party own (first or second mortgage). It’s often chosen by younger businesses that have a strong product and early traction but not yet the trading history an unsecured lender wants. No financials or tax returns are needed for the initial assessment.

Protect yourself before you scale

• Scale gradually. Doubling a budget overnight often resets the platform’s learning and pushes costs up. Step increases of 20–30% give you cleaner data.
• Watch blended numbers. Platform-reported ROAS can flatter itself. Compare total revenue against total ad spend across all channels (sometimes called MER).
• Keep a stop-loss. Decide in advance the result that would make you pause spend.
• Stock up before you scale. A winning campaign that sells out wastes the momentum. If stock is the constraint, look at peak season stock funding or import order funding alongside this.
• Plan for costlier clicks in Q4. Competition for attention rises heavily around Black Friday.

Example scenario

Example scenario — generic and illustrative only. A Nelson-based supplement brand has run Meta ads for a year with a steady blended ROAS well above its break-even. The founders want to add TikTok and a creator programme for summer. They choose a line of credit sized to turnover, draw as each new channel ramps, and set a 60-day review point where they’ll pull back if blended results drop below their stop-loss.

Start with a quick enquiry

When your numbers make sense, send an enquiry. It takes about a minute and won’t affect your credit score. A lending specialist will call to talk about the size and shape of funding that fits your campaign plan.
