Lease Math: IONIQ 9 effective monthly cost beats smaller IONIQ 5

The Hyundai IONIQ 9 currently offers a lower effective monthly lease cost than the more popular IONIQ 5, despite the larger vehicle carrying a significantly higher sticker price. For drivers weighing the two electric SUVs, the three-row model provides a cheaper monthly commitment on specific terms.

The IONIQ 5 remains the top-selling non-Tesla electric vehicle in the United States, ranking third overall behind the Tesla Model Y and Model 3. Its market position relies partly on an accessible entry price. Following the expiration of the federal tax credit in September 2025, Hyundai reduced IONIQ 5 prices by nearly $10,000 on certain trims. The 2027 model year IONIQ 5 SE now starts at $35,250. The IONIQ 9 starts at $58,955, a difference of nearly $24,000.

Lease structures alter that price hierarchy. Hyundai lists the standard-range IONIQ 5 SE at $359 per month for 24 months with $4,999 due at signing. This calculates to an effective cost of $567 per month. The extended-range SE RWD lists at $369 per month for the same duration, resulting in an effective cost of $577 per month. Both figures exceed the effective monthly cost of the larger IONIQ 9.

The IONIQ 9 is advertised at $419 per month for 36 months, also with $4,999 due at signing. This structure yields an effective cost of $557 per month. Using Hyundai's own payment calculator, leasing the 2027 IONIQ 5 SE for 36 months with identical signing fees costs approximately $412 per month, or $550 effective. The gap between the two models narrows to just $7 per month on these comparable terms.

The IONIQ 9 provides more physical space and range than the IONIQ 5. The base IONIQ 9 SE offers an EPA-estimated range of up to 335 miles, compared to up to 245 miles for the standard IONIQ 5 SE. The IONIQ 9 features three rows with seating for six or seven people and up to 163.54 cubic feet of interior volume. The IONIQ 5 is a two-row midsize SUV with room for five and up to 106.5 cubic feet of interior volume.

Both vehicles are manufactured at Hyundai's Metaplant America facility outside Savannah, Georgia. Hyundai data from a facility tour earlier this year indicates that electric SUVs attract new customers to the brand at a higher rate than gas or hybrid models. The IONIQ 5 recorded a 69.8% conquest rate last year, while the IONIQ 9 recorded a 64.3% rate. The Elantra N, Palisade, and Kona Electric followed with conquest rates of 61.9%, 61.2%, and 60.9% respectively.
