Most Singapore agents should start Google Ads at S$1,000–2,000/month in media spend — but the right number scales with the price of what you sell. A HDB-focused agent and a prime-district new-launch specialist face completely different click costs and deal values. Below is a budget framework by tier, the hidden costs agents forget (agency fees, GST, tracking), and the break-even maths that tells you if it's working.
"How much should I spend on Google Ads?" is the wrong question. The right one is: how much is one closed client worth to me, and how many clicks does it take to get one? Answer those two and your budget calculates itself. Get it wrong and you'll either starve a campaign before it can work — or burn S$3,000 chasing leads worth S$1,500.
Here's how to size your budget to what you actually sell.
01 Why a flat number is the wrong answer
Singapore property CPCs sit in the S$5–12 range, and search ads convert to leads at roughly 3% of clicks. That means a single lead can cost anywhere from S$150 to S$400+ in media alone before you've even spoken to anyone. But a lead is not a client — you'll close some fraction of leads. So the budget that makes sense depends entirely on your deal value, which varies wildly by what you sell.
The two numbers to write down first
Before setting any budget: (1) your average commission per closed deal, and (2) your honest lead-to-client close rate. Everything else is arithmetic. If you don't know these, that's the first problem to fix — not the budget.
02 A starting budget by tier
These are sensible media-spend starting points to gather enough data to optimise. They are not ceilings — once a tier is profitable, scale it.
| Your focus | Typical CPC | Suggested monthly media | Why |
|---|---|---|---|
| HDB resale | Lower end (S$3–6) | S$800–1,200 | Lower deal value; keep cost-per-lead tight |
| Mass-market condo / EC | S$5–9 | S$1,200–2,500 | Higher value justifies more reach |
| Prime / new launch | S$8–12+ | S$2,500–5,000+ | Large commissions; competitive keywords |
| Luxury / landed / foreign buyer | Highest | S$3,000–6,000+ | Few buyers, very high value per deal |
03 The hidden costs agents forget
Media spend is not your total cost. The real outlay includes:
- Management fees — if you use an agency, typically 10–20% of media spend, or a flat S$800–1,200/month.
- GST (9%) — applied to both media spend and fees.
- Tracking and tools — call tracking, CRM, conversion setup. Small but real, and skipping it means flying blind.
- The landing page — paid clicks sent to a weak page waste the entire media budget.
A worked example: budget S$3,000 in media and your true monthly cost is closer to S$4,500–5,000 once fees, GST and tools are included. Plan for the full number, not just the media line.
04 The break-even maths
Here's the calculation that tells you if any budget is sane. Suppose your average commission is S$8,000 and you close 1 in 8 leads:
- At S$250 cost-per-lead, 8 leads = S$2,000 to win one S$8,000 deal. 4x return — healthy.
- At S$500 cost-per-lead, 8 leads = S$4,000 to win the same deal. 2x return — thin but viable.
- At S$800 cost-per-lead, you're spending S$6,400 to earn S$8,000. Barely break-even — fix the funnel before scaling.
The lever that moves cost-per-lead most isn't your bid — it's your landing page conversion rate and Quality Score. Lifting Quality Score from 3 to 8 can cut your effective CPC by up to half for the same position. That's why the page matters as much as the budget.
05 How to scale safely
Start at the lower end of your tier for 4–6 weeks to gather data. Watch cost per qualified lead and cost per appointment, not vanity clicks. Once a campaign is profitably under your target cost-per-lead, increase budget 20–30% at a time and re-check — scaling too fast resets the algorithm's learning and spikes costs.
