5G NR Throughput Calculator

Estimate theoretical 5G NR downlink and uplink throughput with carrier aggregation, NRB tables, MIMO layers, modulation, code rate, scaling factor, and TDD slot split.

Carrier Setup

The calculator uses the 3GPP TS 38.306 style throughput formula with normal CP, 14 symbols per slot, and NRB tables aligned to common FR1/FR2 bandwidth and SCS combinations.

Adjust parameters and calculate.

Calculation Notes

  • NRB table: based on common NR channel bandwidth / SCS combinations for FR1 and FR2.
  • Formula: throughput = layers × modulation order × scaling factor × code rate × NRB × 12 × 14 × slots/s × (1 - overhead) × duplex share.
  • TDD split: downlink and uplink share are derived from configured DL, UL, and flexible slot symbols.
  • SDL/SUL: supplemental downlink disables UL throughput, supplemental uplink disables DL throughput.
  • Code rate: default is the commonly used peak assumption of 948/1024 = 92.578%.
  • Extended coverage: includes FR1 35 MHz and 45 MHz bandwidths, plus 1024QAM where the device and network support it.
