How do I calculate AI receptionist ROI for my business?

Use this formula: Missed calls per week × Conversion rate × Average transaction value × 4.33 weeks = monthly missed revenue. Then estimate AAA captures roughly 70-85% of that. Subtract AAA cost ($149/month for Starter, ex GST). The result is your monthly net gain. Annualise for 12-month ROI.

How accurate is this calculator?

The calculator uses honest mid-range assumptions based on common Australian SME patterns and published industry benchmarks. ROI estimates are illustrative — actual results depend on your specific missed-call rate, conversion rates, transaction values, and how effectively you action AAA captures. Use the outputs as a starting point, not a guarantee.

Where do these numbers come from?

Sector baselines are illustrative assumptions informed by publicly available industry conversion benchmarks — they are not measured results from our clients. Where we make assumptions, we mark them in the sector notes. The formula itself is standard ROI maths — no hidden multipliers, no inflated recovery rates.

Do I need to give my contact details to use this calculator?

No. The calculator runs entirely in your browser. We don't capture inputs, results, or contact details unless you choose to book a free 30-minute demo with Niel or contact us directly. Privacy Act 1988 (Cth) compliant — your numbers stay on your device.

What's a realistic conversion rate for missed calls?

15-35% depending on industry. Tradies typically 20-30%, medical 60-80% (new patient enquiries), legal 30-50%, mortgage broking 35-55%. Use the low end of your range to be conservative.

What percentage of missed calls does AAA actually capture?

We assume 65-85% as a realistic planning range. Some callers refuse to engage with anything but a human and hang up — Steve doesn't recover those. The range is an illustrative assumption, not a guaranteed or measured result.

What's the payback period for AAA?

For most SMEs with regular missed-call patterns, payback is 1-3 weeks. For very high-value industries (mortgage broking, real estate, legal), payback can be a single captured lead. For very low-volume businesses, payback can stretch to 2-3 months.

Is AAA worth it for a solo trader?

If you're missing 3+ calls per week with average job value $200+, yes. Below that, voicemail with prompt callbacks may be cheaper. Solo tradies, solo brokers, solo conveyancers all routinely see strong ROI.

Does AAA help with after-hours calls specifically?

Yes — and after-hours calls often have the highest conversion rates because the caller is actively shopping. Most SMEs see disproportionate ROI from after-hours captures.

What if my average transaction value is very low (under $100)?

ROI maths get tougher. You'd need very high call volume (50+ missed calls/week) for AAA's $149/month to make sense. For retail or low-value businesses, evaluate against your specific numbers carefully.

How accurate are the sector benchmarks?

They're illustrative assumptions based on common patterns across Australian SMEs, and your business may differ. Use them as starting points, not absolutes. Spend 15 minutes calculating your real numbers.

Can I get a custom ROI projection for my business?

Yes. Email info@aussieaiagency.com.au with your industry, team size, and average transaction value. We'll send you a custom ROI projection within one business day.

Does AAA ROI improve over time?

Yes. As we fine-tune Steve on your real calls and your team adapts to actioning AAA notifications, conversion rates typically improve. First month ROI is usually conservative compared to month 6+.

Is there a free demo to test ROI before committing?

Yes — book a free 30-minute demo with Niel. You hear the AI receptionist handle calls like yours and we walk through the ROI numbers for your business before you pay anything. There is no money-back refund, but plans are month-to-month with no lock-in, so you can cancel any time.

What's the most common ROI mistake SMEs make?

Underestimating their missed-call rate. We see businesses think they 'rarely miss a call' then check their call logs and find 15-20 missed calls/week. Always check the actual call log before assuming.

Quick Answer

Most Australian SMEs underestimate how much revenue they lose to missed calls. The basic formula is: missed calls per week × conversion rate × average transaction value. For a typical tradie missing 8 calls a week with 25% conversion at $450 average job, that's roughly $3,900/month lost. AAA Starter at $149/month can capture most of it — paying for itself many times over.

This page walks through the calculation, gives sector-specific benchmarks, and shows realistic payback maths across the most common Australian SME industries. ROI estimates are illustrative — actual results depend on operational specifics.

Sector benchmarks for typical 12-month ROI (illustrative):

Tradies: 8-15x, payback 1-3 weeks
Medical (lifetime value): 10-30x, payback 1-4 weeks
Mortgage brokers: 15-50x, payback 1-2 weeks
Real estate: 20-100x+, payback days (one captured listing)
Conveyancing: 5-10x, payback 1-2 weeks
Accountants (lifetime): 30-300x, payback 1-3 weeks
Legal: 5-15x, payback 1-3 weeks

The formula in one paragraph

Lost revenue = missed_calls/week × conversion_rate × avg_transaction_value × 4.33 weeks/month

Worked example (typical Australian plumber):

8 missed calls/week
25% would have converted to jobs
Average job: $450
Weekly lost: 8 × 0.25 × $450 = $900/week ≈ $3,900/month

AAA Starter captures roughly 70-85%:

Recovered revenue: ~$2,700-$3,300/month
AAA cost: $149/month
Net gain: ~$2,400-$3,000/month
ROI: 800-1,000% annualised
Payback: roughly week 2 of month 1

How to think about ROI realistically

ROI calculations are often presented with implausible upside numbers (“save $50,000/year!”) that don't survive scrutiny. The honest version:

1. Not every missed call is a lost sale. Some are wrong numbers, telemarketers, existing customers with non-urgent queries, or callers who'll happily wait for a callback. Realistic conversion rate of missed calls is 15-35% depending on industry.

2. AI receptionist doesn't capture 100% of lost calls. Some callers refuse to talk to anything but a human and hang up. Realistic AI receptionist recovery rate is 65-85% of otherwise-lost calls.

3. Some captured calls take weeks to convert. A medical practice captures a new patient — they don't generate revenue until they actually show up and pay. Time-to-revenue varies by industry.

4. Sector-specific dynamics matter. A real estate listing captured is potentially $20,000+ commission. A retail enquiry captured is potentially $50 sale. The same “captured call” carries very different revenue.

This page uses honest numbers. Where we make assumptions, we've marked them clearly.

Honest interpretation: these numbers look enormous because they are. But two things are true: (1) the maths is real — for businesses with regular missed-call patterns and material transaction values, AAA pays back rapidly; (2) the numbers only work if your business actually has the missed-call pattern. If you're answering every call already, the recovered revenue is minimal.

When the ROI maths don't work

Very low call volume. If you have under 3 missed calls per week, AAA's monthly cost may exceed your monthly recovery. Voicemail with prompt callbacks may be more cost-effective.

Low average transaction value. Retail businesses with $20-$50 transactions need extremely high call volume for ROI to work. AAA's strength is mid-to-high average transaction value businesses.

Already-low missed-call rate. If you have a full-time receptionist already handling 95%+ of calls in business hours, AAA's incremental value is small (mostly after-hours and weekends).

Long sales cycles where revenue is months away. Some industries (commercial real estate, complex SaaS sales) have 6-12 month sales cycles. AAA still captures the initial enquiry, but ROI takes longer to materialise.

Repeat-only customer base. If 90% of your work is existing customers who'll happily wait for a callback, missed-call recovery has limited value.

For everyone else — and that's the vast majority of Australian SMEs — the ROI maths work.
