The difference between money you can use and money you can only use one way, and why mixing them up is one of the most common early nonprofit mistakes.

Here's a scenario that surprises almost every new nonprofit leader: the bank account shows a healthy balance, but the organization can't pay this month's rent. Nothing shady happened. The money is simply restricted — and understanding what that means is foundational to running a nonprofit that survives.
When a donor or funder gives with conditions attached ("this is for the youth program," "this must be spent next fiscal year"), the gift is restricted. The organization legally must honor those conditions. Accounting standards call these funds "net assets with donor restrictions."
When money arrives with no strings (a general donation, most individual gifts, earned revenue), it's unrestricted. It can pay for anything the mission requires: rent, salaries, the software subscription, the electric bill.
The restriction comes from the donor's intent, not from what the money is spent on. A board can set aside unrestricted money for a purpose (a "board-designated" fund), but it can also undo that decision. A donor restriction can only be changed by the donor.
Program-restricted money is easier to raise; funders love funding visible programs and are historically reluctant to fund "overhead." So young nonprofits often build budgets that are majority-restricted. The result: programs are funded, but nobody funded the organization that runs them. This is how a nonprofit can grow its revenue every year and become more fragile at the same time.
Three habits protect you:
Restricted money funds programs; unrestricted money keeps the organization alive. Watch the ratio, raise unrestricted funds on purpose, and never let a bank balance fool you — the number that matters is the unrestricted portion of it.
