What it means
The term was coined as a counterpart to DINKs (dual income, no kids). Where DINKs enjoy two salaries and few commitments, DEWKS have two salaries but a growing list of expenses.
Marketers and economists use the label to describe a distinct group of consumers. Two incomes bring benefits, such as greater earning power and a built-in safety net if one partner loses their job.
However, children bring costs that are large and hard to avoid, including childcare, food, health care, school fees and a bigger home. For many families, the second salary pays a large part of the childcare bill.
DEWKS are an important target for banks, insurers and retailers. They need life and disability insurance, savings plans for education, mortgages, and products that save time.
Because both adults work, they often value convenience and are willing to pay for services that give them back hours in the week. For personal budgeting, the key challenge is balancing present spending with long-term goals.
A common mistake is to spend heavily on housing and childcare while neglecting retirement saving and an emergency fund. Planners often suggest keeping several months of expenses in reserve and reviewing insurance as the family grows.
Tax rules matter too. Some countries offer childcare credits, child benefits or deductions that change the maths of whether both parents should work full time.
Because these rules change from time to time, families should check the current position in their own country. The label is a generalisation.
Households vary enormously, and not every working couple with children has the same income or spending pattern. Treat it as a starting point for thinking about a customer group, never as a description of any single family.
In practice
Real-world examples.
Example
A marketing manager and a nurse have two children under six. They compare the cost of full-time childcare at $2,000 a month with the possibility of one parent reducing hours, and choose to keep both jobs.
Example
A bank designs a family package for DEWKS that combines a mortgage, an education savings account and low-cost life cover. It markets the package through online channels because both parents are short of time, and it lets them complete the application in a single evening on their phones.
Example
A supermarket chain launches a delivery subscription aimed at working parents. It prices the service at $10 a month because research shows busy families will pay to avoid a weekly shop.
Formula
Calculation
Discretionary income = Combined take-home income - Fixed costs - Childcare and child costs
Suppose a couple earns a combined take-home income of $9,000 a month. Fixed costs such as mortgage, utilities, transport and insurance are $4,200, and childcare and child costs are $2,400. Discretionary income is $9,000 - $4,200 - $2,400 = $2,400 a month, of which the couple decides to save $1,200 for education and retirement and keep $1,200 for everything else.Case study
Seen in the real world.
The Okafor family is a fictional household used here as an illustrative example. Both parents work full time with a combined take-home income of $8,500 a month, and they have two young children.
After childcare, housing and other fixed costs, they are left with only $1,100 a month, and they have no emergency fund. A financial planner suggests moving $400 a month into a savings account until they have three months of expenses saved, and reviewing their life and disability cover. She also recommends using a tax-advantaged childcare account if their country offers one, and setting up an automatic transfer on payday so the saving happens before the money is spent.
Within two years the family has an emergency fund of about $9,600 and has increased its insurance. The family's story is a simple illustration of how a strong income can still leave little margin once children arrive.
Watch out
Common mistakes.
- Assuming two incomes means plenty of spare money. Childcare, housing and education can absorb most of the second salary.
- Skipping retirement saving while children are young. Delaying contributions reduces the growth that compounding can provide.
- Relying on both incomes without a back-up plan. If one parent loses their job or becomes ill, insurance and savings are essential.
Questions
People also ask.
How is DEWKS different from DINKs?
DINKs have two incomes and no children, so they usually have more spare money and flexibility. DEWKS have the same income advantage but higher and less flexible costs.
Why do businesses care about DEWKS?
They are a large and valuable group of customers who need many financial and household products, from mortgages and insurance to groceries and holidays. They also tend to value time-saving services and are often willing to pay for convenience.
Is DEWKS an official statistical category?
No, it is an informal label used in marketing and personal finance discussions. Official statistics usually group households differently.
