What is cash flow planning?
Cash flow planning tracks the money coming in against what goes out, so you know what you can spend, what to hold back, and where each extra dollar should go.
How big should your emergency fund be?
Cash flow planning starts with an emergency reserve. Size it on essential expenses, not total spending: housing, utilities, food, insurance, minimum debt payments, childcare, and any tax not covered by withholding. Then choose a number of months based on how likely a loss of income is and how long it could last.
| Your situation | Starting point |
|---|---|
| Two steady incomes | 3 months of essential expenses |
| One steady income | 6 months |
| Commission, bonus-heavy, or self-employed income | 6 to 12 months |
| A large share of pay in company stock | Size it on base salary; vested shares can fall with the company |
| Retired or close to it | 1 to 2 years of spending in cash or short-term bonds |
Where should you keep your emergency fund?
Somewhere safe, quick to reach, and paying interest.
- 01
High-yield savings or money market
FDIC-insured up to $250,000 per depositor, per bank.
- 02
Treasury bills
Interest skips state and local tax.
- 03
Not stocks or long-term bonds
They can be down when you need the cash.
What should you do with cash above your emergency fund?
Cash left in checking above what you need gives up the interest a high-yield savings account or Treasury bills would pay. Give every dollar above the reserve a job, in roughly this order.
Set aside known bills
Hold the next 12 to 24 months of known bills in savings or Treasury bills: a tax balance from RSU vests or a bonus, tuition, a home down payment, a car.
Get the full employer match
Contribute enough to your 401(k) to get the full employer match.
Pay off high-interest debt
Clear high-interest debt, such as credit card balances.
Fund an HSA and an IRA
An HSA ($4,400 self-only or $8,750 family in 2026) and an IRA or backdoor Roth IRA ($7,500).
Raise 401(k) contributions
Work toward the $24,500 limit.
Invest the rest
Use a taxable brokerage account for goals five or more years out, or weigh paying down a higher-rate mortgage.
How do you build a monthly cash flow plan?
Pull three months of transactions and sort them into fixed bills, everyday spending, and irregular costs that come once or twice a year, such as insurance premiums, travel, and property tax. Divide the irregular costs by 12 and set that much aside each month so they stop feeling like emergencies.
Build the monthly budget on base take-home pay. Treat bonuses, RSU vests, and other irregular income as money for goals and taxes, decided before it arrives, so spending does not rise with every windfall. Managing a windfall covers the tax side of a large payment.
How Nino helps with cash flow planning
Cash flow planning shows how money coming in covers spending, debt payments, and savings over time. It helps you decide what you can spend now and what needs to stay available. Nino’s AI software brings connected transactions together; your human team can help set priorities and turn them into a financial plan.
Book a free consultation-
Understand your usual spending
Separate recurring bills from one-time purchases, and compare them with take-home income. A vacation can make one month unusually expensive; predictable annual bills still need a monthly allowance. Use Nino’s transaction view to see where the money went and ask what changed.
-
Give upcoming bills a place
Set aside cash for costs you can see coming, such as tuition, taxes, insurance, or a move. Keep those commitments separate from an emergency reserve for unexpected expenses or lost income. The right reserve depends on your household’s obligations and how reliable your income is.
-
Choose where the next dollar goes
Once your bills and reserves are covered, compare debt payments, retirement contributions, and other savings goals. Interest rates, employer contributions, and when you need the money all matter. With services, your team helps choose priorities that fit your household rather than a generic spending rule.
-
Plan for a change in income
A raise, career break, new child, or business launch can change both income and expenses. Explore the monthly gap and how long savings could cover it. Adjusting the plan before the change gives you time to build reserves or reconsider the timing.
