How we calculate true cost
The True Annual Cost takes the school’s mid-point USD tuition and adds city-calibrated extras for transport, uniform, registration recurrent, lunch, technology fee, and activity fees. The number is scaled by tier — premium-tier schools tend to charge proportionally higher capital levies and ancillary fees than budget schools.
