Our Mission

Provide 20+ free, accurate, fast calculators for Pakistan with live rates via /api/* showing Fetched At timestamp, 100 percent client side privacy, no signup. Built for Pakistanis in Sargodha, Lahore, Karachi, Islamabad.

How We Create Content

  3. Verify: We test with real payslip, electricity bill 300 units, gold 2 tola, USD 1000, BMI 70kg 173cm, marla 5
  4. Humanize: Add first-person local examples Sargodha, Lahore, Karachi, Urdu words Bijli Tola, mixed short long sentences, no AI phrases

Fact Checking

Every rate has timestamp: Rate Last Updated from official notification date plus Fetched At auto on page open via /api/* . For example gold via /api/gold shows last updated from gold-api.com plus fetched at time user opens link. Tax slabs via /api/tax-slabs with budget date 2026-06-13. Electricity slabs via /api/electricity with NEPRA date 2025-07-01. Forex via /api/forex hourly. Petrol via /api/petrol tries live scrape plus fallback OGRA 11 July 2026.
