Tough Love Lending: Why Parents Are Charging Their Grown Kids 5.1% Interest

The Bank of Mom & Dad Just Got Tougher

For decades, the Bank of Mom & Dad has been the most forgiving financial institution in America—no overdraft fees, no hidden charges, and repayment schedules as loose as the family fridge calendar. However, parents charging kids interest on loans is becoming more common, revealing that even parents have limits.

In a survey of 3,014 parents, MarketBeat found that many are now charging their grown children interest on family loans, averaging a surprisingly precise 5.1%. That’s still a bargain compared to today’s national average personal loan rate of 11.25% (Federal Reserve, FRED database). Consequently, parents charging kids interest on loans has made it more structured and formal.

Where Parents Charge the Most

Not all states are created equal when it comes to tough love lending. Parents in Nebraska and Oregon top the list, charging their adult children an average of 6.8% interest—higher than some credit card promotional rates. Moreover, this trend of charging kids by parents reveals broader shifts in family dynamics.

Top 5 States With the Highest Parent-to-Child Loan Interest Rates:

Nebraska – 6.8%
Oregon – 6.8%
Mississippi – 6.5%
Georgia – 6.4%
Arkansas – 6.3%

When Parents Expect Repayment

Patience may be a virtue, but not all moms and dads have endless amounts of it. Over 40% of parents charging kids interest on loans expect repayment within six months, reflecting a trend towards treating family loans more like structured financial agreements than open-ended gifts.

Within 1 month: 21%
Within 6 months: 21%
Within 1 year: 15%
More than 1 year: 8%

That means more than 4 in 10 parents expect repayment within six months, treating family loans more like structured financial agreements than open-ended gifts.

Inflation Is Changing Family Finance

With rising living costs, half of parents say inflation has impacted how much they’re willing to lend. For some, generosity is unchanged. For others, the purse strings are tighter than ever in the context of parents charging interest to their kids on loans.

59% say helping their kids brings no stress.
27% do it reluctantly.
4% admit to feeling resentful.

And while money is often emotional, only 14% say lending has damaged their relationship with their adult children.

Expert Take

MarketBeat founder Matt Paulson sums it up:

“The Bank of Mom & Dad has always been generous, but even generosity comes with boundaries. What’s striking is that while most parents don’t expect repayment – and certainly not at commercial interest rates – inflation and rising costs are starting to reshape how families think about money. In many cases, these family loans aren’t just financial lifelines; they’re also emotional transactions that test trust, responsibility, and family dynamics.”

What It Means for Families

Whether you’re a parent debating whether to charge interest, or an adult child wondering how to approach Mom or Dad for a loan, the takeaway is clear: The dynamics are changing, with parents now charging their kids interest on loans.

Talk openly about terms. Interest rates, repayment expectations, and boundaries should be clear.
Recognize the emotional weight. Loans within families aren’t just financial—they can impact relationships.
Remember it’s still a gift. Even at 5.1%, the Bank of Mom & Dad is more generous than any commercial lender.
