Average hourly rates by region.

Where you hire affects what you pay by up to 3×. Comparable quality is available across regions - the rate gap between the priciest and cheapest is the single biggest lever on a project budget.

Average hourly rate · USD

USNorth America$106/hr$106
AUOceania$92/hr$92

INSouth Asia$39/hr$39

What the gap actually buys you

The rate gap between the highest- and lowest-cost regions is largely a cost-of-living and labor-market gap - not a quality gap. Top-tier firms in lower-cost regions routinely deliver work competitive with premium markets at a fraction of the cost.

That said, time-zone overlap, language alignment, and IP protection vary by region. Eastern Europe and LATAM hit a sweet spot: meaningful cost savings with same-day overlap for US/EU clients.

~70%

Typical cost savings when moving a $100K/year dev contract from a premium market to a top value destination - comparable skill, comparable delivery quality.

Match by work-hour overlap with your team.

Cost matters - but so does being able to actually talk to your developer during your workday. Here are the best destinations for each major hub.

If you're in US (PT/ET)Recommended

Look for nearshore LATAM partners - same-day collaboration, similar time zones, and 50-60% cost savings vs domestic.

MXMexico~7h overlap
ARArgentina~6h overlap
BRBrazil~5h overlap
CACanada~8h overlap
If you're in Europe (CET/GMT)Recommended

Eastern Europe is your sweet spot - 1-2h time zone shift, EU GDPR alignment, and 40-50% lower rates than Western Europe.

Every cell in the grid above is the count of firms in (place × hourly-rate tier). Firms are placed by their published hourly rate; those without a disclosed rate are not plotted.

Top company names per cell are surfaced by Value Score - a weighted blend of affordability (50%) + rating (35%) + review volume (15%).
