Wage to Wallet Index Targets the Side Hustle Economy

By Priya Raman

PYMNTS.com launched its Wage to Wallet™ Index, a recurring measurement product tracking side work patterns in the labor economy.

For Daniela, a school nurse who books weekend photography jobs, the line between one paycheck and two has blurred. Her salary deposit lands on Friday. Her side earnings land whenever a client pays. The new index aims to measure how households like hers combine those income streams.

The product name captures the analytical arc it intends to trace. The index follows earnings from the paycheck to the moment workers spend or save them. PYMNTS.com, a research outlet that covers payments and commerce, has built a body of work on how money moves through households. The Wage to Wallet™ Index extends that research toward labor income.

What does the index measure?

The index's stated focus is side work patterns. Side work refers to paid activity outside a worker's main job. The category covers platform-based tasks, freelance contracts, and informal cash work. The new product positions itself as a way to track how these income sources combine with primary paychecks.

PYMNTS.com's payment-systems coverage gives the index a defined analytical home. The company has tracked consumer financial behavior across multiple research products. Side work sits at the intersection of those lines. Wage inflows and wallet outflows form the analytical bookends.

What does this change for workers?

Workers asking the practical question — "does this index describe me?" — will need to read the underlying methodology once PYMNTS.com releases it. The index's first edition will set the baseline. Until then, readers can look for three things:

• The sample size
• The definition of side work adopted
• The time period the index covers

For workers, the appeal is benchmarking. A regular measurement of secondary income helps individuals place their own arrangements. It also helps job seekers gauge whether the labor market rewards income diversification.

For employers, the index signals where talent pools sit. Companies hiring for flexible or part-time roles gain a read on how many workers already split their time. That shapes recruiting strategy.

For economists, the index adds a data series to consumer-spending and labor-supply models. Side income affects savings rates, discretionary spending, and household resilience during downturns. A regular measurement of those patterns carries analytical weight.

What comes next?

The index carries a forward-looking question. Side work arrangements evolve as platforms change payment structures and as tax treatment shifts. An index built on today's definitions will need periodic revision to remain useful, especially given how quickly platform-payment rules and labor classifications can change. PYMNTS.com's reputation for payment-systems research suggests the methodology will receive scrutiny.

The labor economy keeps generating new income arrangements. Workers, employers and analysts will want measurement tools that keep pace with them. The Wage to Wallet™ Index joins that queue; its analytical value will turn on what comes next.
