Free Google Ads budget & CPC calculator
This free tool — built by a Singapore digital marketing agency — projects what a Google Ads (or any PPC) budget will actually produce: monthly clicks, conversions, cost per conversion, revenue and estimated ROAS. Change any input and the forecast updates instantly. It’s currency-agnostic, so enter your figures in SGD or whatever you plan in.
The four inputs that drive paid-search results
- Budget sets your ceiling — how much you’ll spend per month.
- Average CPC is what each click costs; it varies hugely by industry and keyword competitiveness in Singapore.
- Conversion rate is the share of clicks that turn into a lead or sale — the biggest lever most advertisers under-optimise, driven by landing-page quality and offer.
- Average order / customer value converts conversions into revenue. For lead-gen, use the average value of a closed deal, not a raw lead.
How to improve each number
If the projected ROAS is below target, you have three levers. Lower CPC by improving Quality Score, tightening match types and cutting wasteful search terms. Raise conversion rate with faster, clearer, more relevant landing pages and stronger offers — this is usually the highest-leverage fix. And increase average order value through upsells, bundles or better lead qualification. Small gains compound: a CPC 20% lower and a conversion rate 20% higher together nearly halve your cost per conversion.
Realistic expectations for Singapore paid search
CPCs in Singapore vary from under a dollar for low-competition terms to well over $10 for competitive commercial keywords (legal, finance, B2B services). Rather than anchor on a benchmark, use this calculator with your own numbers, then set a target ROAS above your break-even ROAS. Remember paid search buys traffic only while you pay; pairing it with organic SEO builds compounding visibility that keeps returning after the ad spend stops.
Frequently asked questions
How much should I budget for Google Ads in Singapore?
Work backwards from goals: decide how many conversions you need, multiply by your cost per conversion (CPC ÷ conversion rate), and that’s your budget. This tool does the maths — adjust budget until the conversions and ROAS meet your target.
What’s a good conversion rate for Google Ads?
It varies by industry, but many accounts sit between 2% and 6% on search. It’s also the most improvable input — landing-page and offer improvements often lift it more than any bidding change.
Is this calculator only for Google Ads?
No — the same click, CPC, conversion-rate and value model works for Meta, LinkedIn, TikTok and any pay-per-click channel. Just enter that channel’s average CPC and conversion rate.
Does a ROAS above 1x mean I’m profitable?
Not necessarily — 1x only means revenue equals spend. To know true profit you need your margin; use our ROI & ROAS calculator for margin-adjusted profit and break-even ROAS.
