Google Maps API Cost vs GoGoDuk: Real Numbers for a Vietnam Startup
What a Vietnamese app actually pays Google Maps for geocoding, autocomplete, and map loads — with a worked monthly bill — versus a free-forever Vietnam map API.
Most "Google Maps is expensive" posts stop at the per-1,000 price and leave you guessing. This one does the opposite: we take a normal Vietnamese app — address search at checkout, a few geocodes, a map on the page — and add up the real monthly bill. Then we put the same workload on GoGoDuk's free Vietnam map API and compare.
If you are deciding whether to start on Google or look for a Google Maps API alternative, this is the math that actually matters.
The SKUs a Vietnam app actually hits
A typical location feature touches three Google Maps Platform SKUs, not one. Here are the 2026 list prices per 1,000 requests, after the free tier:
| SKU | What triggers it | Price / 1,000 |
|---|---|---|
| Places Autocomplete (per session) | Each address-search session at checkout | $10.00 |
| Geocoding API | Turning an address into lat/lng | $5.00 |
| Dynamic Maps | A JavaScript map loading on a page | $7.00 |
Prices are Google Maps Platform list prices as of 2026 and change over time — always check the official pricing page before you commit. Google gives ~10,000 free events per SKU per month; the old universal $200 monthly credit is gone.
The trap is the per-session autocomplete SKU. People see "$2.83 per request" and budget for that, but session pricing bills $10 per 1,000 sessions — and an abandoned session (user types, never picks) is billed as unsessioned requests anyway. The real number is usually higher than the one you planned for.
A worked monthly bill
Say you run a small but real Vietnamese commerce app:
- 30,000 checkout sessions/month → 30,000 Autocomplete sessions
- 30,000 geocodes/month (one per confirmed order)
- 60,000 map loads/month (product pages + checkout + tracking)
Subtract Google's 10,000 free events per SKU, then bill the rest:
| SKU | Billable (after free) | Cost |
|---|---|---|
| Autocomplete sessions | 20,000 | $200 |
| Geocoding | 20,000 | $100 |
| Dynamic Maps | 50,000 | $350 |
| Total | ≈ $650 / month |
That is roughly 16 million VND a month, in USD, billed to a card — before VAT handling on your side and before traffic grows. Double the traffic and you are near $1,300/month. None of this includes the engineering time spent watching the dashboard so a viral day does not produce a surprise invoice.
The same workload on GoGoDuk
GoGoDuk is free forever — 100 requests/day per account, with higher limits on request, no credit card, and pricing in your favor instead of per-SKU USD billing. The endpoints map one-to-one onto the Google features above:
/v1/suggestreplaces Places Autocomplete/v1/place/resolvereplaces Place Details/v1/reversereplaces Reverse Geocoding
For map tiles you self-host or use MapLibre, so there is no per-load "Dynamic Maps" meter running at all. The autocomplete-then-resolve flow is the same shape you already write for Google, so migrating is mostly swapping a base URL and a response field — see the 5-minute migration guide.
When Google still makes sense
Be honest about the trade: Google's data is global and battle-tested. If you serve users outside Vietnam, need worldwide POIs, or rely on Google-specific features (Street View, lane-level traffic), pay the bill — it is worth it.
But if your users are in Vietnam, addresses are Vietnamese, and the monthly invoice above made you wince, a Vietnam-first map API gives you better local address quality at a fraction of the cost. For a broader feature-by-feature view, see the best Vietnam map APIs in 2026.
