Practical Financial Management: Build A Three-Month Buffer
Consultant Brooke Benson discusses the importance of setting aside a 90 buffer to cover expenses during slow seasons.

I used to let unpaid invoices run my life. Rent day was a coin toss, and I spent way too much energy stressing instead of creating. The fix wasn鈥檛 more hustling, I simply made a non-negotiable pact with myself: get three months ahead of bills 鈥 full stop.聽
Today, late payments still happen (showbiz gonna showbiz), but they no longer decide whether I can pay rent or take a day off. Here鈥檚 the system I use and teach to other solopreneurs and self-employed entrepreneurs so they can buy the same peace of mind.
Calculate Your Two Baselines
- Business Baseline: Average monthly operating costs (software, contractors, taxes, etc.).
- Personal Baseline: Rent or mortgage, groceries, utilities.
Clarity is power. You can鈥檛 protect what you haven鈥檛 counted.
Triple Those Numbers
Take each baseline and multiply by three. That鈥檚 the amount you鈥檒l keep on standby:
- Business Reserve: 3 脳 Business Baseline
- Personal Emergency Fund: 3 脳 Personal Baseline
Keep these two funds separate so business slowdowns don鈥檛 spill into your personal life (and vice-versa).
How to Maintain It
- Automate from Day One: I use my bank鈥檚 Reserve feature to automatically transfer 25% of every payment straight into the buffer. If your income swings a lot like mine does, percentages (rather than flat amounts) helps keep your savings flexible.
- Treat Savings Like Rent: Pay your buffer before you take profit. High-earning month? Great鈥攜our future self gets a raise.
- Sweep the Surplus: At month-end, anything above your baseline goes straight into the buffer. Small, steady sweeps build momentum fast.
Non-negotiables
- Your Buffer isn鈥檛 a聽 Piggy Bank: Touch it only for true emergencies that you have defined beforehand.
- Top-up before you trade-up: Want that new camera lens? Great! Make sure you refill your Buffer afterwards.聽
- Quarterly Check-in: Recheck your baselines every quarter. Expenses creep up, and your buffer should keep pace.
If you keep this advice in mind, it won鈥檛 be long before you have a聽 90-day buffer, one that will shield you from income dips, and give you space to breathe even when the season is slow.聽
The goal isn鈥檛 perfection. Every step you take toward that buffer, every automatic transfer, every month you sweep a little extra aside, you鈥檙e one step closer to peace-of-mind.聽
鈥Three months ahead means three months of peace. A buffer allows you to seize the good surprises: discounted gear, dream conferences, or a pivot that needs upfront capital. It buys you time to think strategically instead of reacting desperately.
