BYD Sealion 7 Dynamic cost to own in Singapore — the true 5-year total
As of August 6, 2026, the BYD Sealion 7 Dynamic costs S$277,888 on the road (price with COE). Over 5 years, owning one (EV) costs about S$155,209 in Singapore — S$2,587/month, S$1.77/km — where COE and ARF, not electricity, dominate. That's S$20,527 less than a comparable Honda CR-V 1.5 VTEC Turbo (7-Seater) over the same 5 years.
COE is set by a biweekly auction and swings thousands of dollars — every figure here uses the S$124,790 (Cat A) / S$126,236 (Cat B) COE assumption. Confirm the current COE before you commit; it is the single biggest line in the price. Source: LTA registration-cost sheet, 2026-08-06.
EV Early Adoption Incentive: the EEAI (45% off ARF, capped S$7,500) is baked into the EV figures for 2026 registrations — and it sunsets 31 Dec 2026. Register a BEV from 2027 and it costs more. Source: LTA.

Where the money really goes — COE + ARF dwarf the fuel
The registered price with COE for the BYD Sealion 7 Dynamic is S$277,888. COE + ARF alone are S$138,771 of that — many multiples of the electricity or petrol you'll ever buy. That is the honest story of Singapore car cost.

How depreciation works here: it is the registered "price with COE" minus what you get back at de-registration — the unused COE (rebatable over the 10-year licence), the PARF rebate (a capped % of ARF paid), and the car's remaining market value. Where a published Singapore depreciation figure exists (PaperValue / sgCarMart), we use it — the straight-line S$/yr buyers actually quote. That is why the S$100k+ upfront, not electricity or petrol, dominates the 5-year total. What you'd get back at deregistration (official PARF + COE rebate) →

Cost to charge the BYD Sealion 7 Dynamic at home
The BYD Sealion 7 Dynamic runs about S$7.69 per 100 km at home — versus about S$23.94 for a typical 7 L/100km petrol car. Home charging only (the ~10% AC charging loss is included); public DC fast-charging is billed per session by each network — often 2–3× the home rate — and isn't in these figures.

What the numbers say
- Not close in Singapore: the BYD Sealion 7 Dynamic costs S$20,527 less than the Honda CR-V 1.5 VTEC Turbo (7-Seater) over 5 years — about 12% of the Honda CR-V 1.5 VTEC Turbo (7-Seater)'s total, and almost all of that decided upfront by COE, ARF and VES rather than by what it drinks.
- On cost per month the BYD Sealion 7 Dynamic ranks #6 of 12 SUV models we price in Singapore.
What the Singapore stack does to the BYD Sealion 7 Dynamic specifically
The BYD Sealion 7 Dynamic declares an OMV of S$37,129 — the import value every Singapore tax on it is computed from. That produces S$43,981 of gross ARF before any adjustment. Its VES band A takes S$22,500 back off that ARF (≤90 g/km CO2 (efficient BEVs, via 0.4 g CO2/Wh factor) → S$22,500 rebate), and the 2026-only EEAI a further S$7,500. It registers in COE category A, so this page prices it at the S$124,790 Cat A assumption — 45% of its S$277,888 registered price on its own, and COE plus ARF together are 50% of it. For scale, the COE alone is about 19× everything the BYD Sealion 7 Dynamic will spend on electricity in 5 years (S$6,729).
The Singapore market quotes depreciation on this car at S$20,900/yr (PaperValue Sealion 7 2025-reg (~S$20,900/yr). OMV S$37,129 + 100kW + VES Band A (CO2 ~80 g/km) from LTA M032 May-2026; retail S$277,888 with COE (LTA M032 distributor-quoted).) — that published figure, not a residual curve of ours, is what drives the 5-year total above. Road tax on the BYD Sealion 7 Dynamic is assessed on motor power — 100 kW, plus the flat S$700/yr Additional Flat Component every EV pays in lieu of fuel duty.
