How the price column is worked out. One search returning 50 sales, one request per search, at each product's published prices. SoldComps.io: A 50-sale search costs 20 + 50 × 1 = 70 credits; Starter: 50,000 credits ÷ 70 = 714 searches for $5, so $7.00 per 1,000 searches; Growth: 300,000 credits ÷ 70 = 4,285 searches for $29, so $6.77 per 1,000 searches; Scale: 850,000 credits ÷ 70 = 12,142 searches for $79, so $6.51 per 1,000 searches; Pay as you go: 50,000 credits ÷ 70 = 714 searches for $6, so $8.40 per 1,000 searches; Fewer sales cost less: a 20-sale search is 40 credits, $4.00 per 1,000 on Starter. sold-comps.com: Starter: $9 ÷ 2,000 requests × 1,000 = $4.50; Growth: $29 ÷ 10,000 requests × 1,000 = $2.90; Scale: $79 ÷ 50,000 requests × 1,000 = $1.58; high-volume plans as listed: $1.29 at 100,000 down to $0.499 at 2,000,000; credits: $3 per 1,000 requests
