Calculation:
Subscription fees:
$654 per month × 3,550 agencies = $2,321,700 MRR
Financing fees:
$395,000 average borrowing per agency × 2% fee × 3,550 agencies = $28,045,000 MRR
Total MRR: $2,321,700 (subscription) + $28,045,000 (financing) = $30,366,700 MRR
Total ARR:
$30,366,700 MRR × 12 = $364,400,400 ARR
This gives a potential ARR of $364.4 million from targeting 5% of the UK and US markets.
