Hyundai IONIQ 9 Lease Economics: Bigger SUV Beats Smaller IONIQ 5 on Monthly Cost

Hyundai has positioned its largest electric SUV, the IONIQ 9, as a competitive lease alternative to its best-selling model, the IONIQ 5. While the IONIQ 5 holds the title of the most popular non-Tesla electric vehicle in the United States, the newer, larger IONIQ 9 currently presents a lower effective monthly cost for lessees through September 2026.

The IONIQ 5 ranks as the third top-selling EV in the country, ahead of the Chevrolet Equinox EV and Ford Mustang Mach-E. Its market position is supported by aggressive pricing following the expiration of the $7,500 federal tax credit at the end of 2025. Hyundai reduced IONIQ 5 prices by nearly $10,000 on certain trims. The 2027 IONIQ 5 standard-range SE now starts at $35,250, while the extended-range SE RWD begins at $37,750.

The IONIQ 9 starts at a higher retail price of $58,955, which is nearly $24,000 more than the base IONIQ 5. However, lease structures alter the financial comparison. The IONIQ 5 SE can be leased for $359 a month on a 24-month term with $4,999 due at signing, resulting in an effective cost of $567 per month. The extended-range version costs $577 per month effectively. The IONIQ 9 is advertised at $419 a month on a 36-month term with the same down payment, yielding an effective cost of $557 per month.

When comparing models on identical 36-month terms, the price difference narrows further. Using Hyundai's payment calculator, the 2027 IONIQ 5 SE costs approximately $412 a month, or $550 per month effectively. This is only $7 less than the IONIQ 9. The IONIQ 9 provides substantially more physical space and range compared to the midsize IONIQ 5.

The IONIQ 9 features three rows of seating and offers six or seven-seat configurations. Its interior passenger volume reaches 163.54 cubic feet, compared to 106.5 cubic feet in the IONIQ 5. Range estimates also favor the larger vehicle; the base IONIQ 9 offers up to 335 miles on a single charge, while the base IONIQ 5 offers up to 245 miles and the extended-range version offers up to 318 miles.

Both vehicles are manufactured at Hyundai's Metaplant America facility outside Savannah, Georgia. During a site tour earlier this year, Hyundai stated that its electric SUVs attract new brand buyers at a higher rate than its gas or hybrid counterparts. The IONIQ 5 recorded a 69.8% conquest rate last year, while the IONIQ 9 achieved a 64.3% rate. The Elantra N followed at 61.9%, the Palisade at 61.2%, and the Kona Electric at 60.9%.
