Build a one-month cash cushion

A small buffer turns a scary slow month into a shrug. Here is how to build one without a big windfall.

Kerythos team · July 5, 2026

Most cash-flow panic is not caused by a bad business. It is caused by timing. A client pays late, a big cost lands early, and suddenly a healthy company cannot cover the week. A cushion is what stands between a timing wobble and a real crisis.

What a cushion actually buys you

The goal is simple: enough set aside to cover one full month of your fixed costs without a single new payment coming in. Rent, wages, subscriptions, the essentials that leave whether you sell anything or not.

That one month buys you the most valuable thing in business: room to make good decisions. With a cushion, you chase a late invoice calmly instead of desperately. You turn down bad-fit work instead of grabbing it out of fear.

A cushion does not just protect your bank balance. It protects your judgment.

Build it in small, boring slices

You do not need a windfall. You need a habit.

  • Set a target. Add up one month of fixed costs. That is your finish line.
  • Pay the cushion like a bill. Move a small fixed amount into a separate account every time you get paid, before you spend on anything optional.
  • Feed it the surprises. A deposit, a bigger-than-usual month, a refund. Send a slice of every windfall straight to the cushion until it is full.

Slow and steady wins here. Even a small slice per payment reaches a full month sooner than you would guess, because you stop raiding it the moment it exists.

Guard it once it is built

A cushion only works if it is boring and untouched. Keep it in a separate account so it does not blur into everyday spending, and give it one clear rule: it is for genuine gaps, not for a slow week you could ride out.

Work out your one-month number today, then move your first slice on the very next payment that lands.
