How Much Should Your Business Be Saving Each Month?

A simple formula for South African SMEs

We all know that feeling. It’s the end of the month, bills have to be paid, payroll has to run and debts must be cleared. Once all that is done, then it’s time to put a little away for savings. The trouble is, some months there is nothing left over, and other months the leftover amount is whatever it happens to be. Neither tells you if your business could survive a slow quarter, a client who pays painfully late, or an unplanned repair bill.

This July marks National Savings Month, and it’s a good time to start thinking about how a solid savings plan actually works? Is there a formula to it and what does that look like? Let’s explore.

Why “whatever’s left over” doesn’t work

Saving from leftovers ties your safety net to your best months. It says nothing about your worst ones, which are exactly the months a safety net needs to cover.

This in particular, matters more for smaller businesses than for larger ones. Smaller operations carry the most exposure to rising costs and slow-paying clients, and have the least room to absorb a shock without it affecting payroll or stock orders. A vague intention to “save more” does not change that. A specific target does, because it gives you something to measure against instead of a feeling to chase.

The two numbers behind the formula

Before you can work out a savings target, you need two things about your own business.

1. Your fixed monthly costs

These are the costs that stay roughly the same whether you have a great month or a quiet one:

• Rent
• Salaries and wages
• Loan or lease repayments
• Insurance
• Software and subscriptions
• Basic utilities, including the average cost of running on backup power during load shedding

Add these up and you have one number: what it costs to keep the doors open for a month, regardless of sales.

2. How predictable your revenue actually is

Be honest with yourself here, since this is the number that decides how big your buffer needs to be:

• Predictable. Contracted clients, retainers, recurring billing.
• Variable. Seasonal trade, invoice-based work with long payment terms, walk-in retail that swings with the month.
• Volatile. Project-based income, heavy reliance on one or two large clients, or a business that loses real trading hours to load shedding or weather.

The formula

Monthly Savings Target = Fixed Monthly Costs × Buffer Months

Use this guide to choose your buffer:

This gives you a reserve target: the amount you want sitting in savings before you ease off on saving and shift focus to growth. As your costs rise, recalculate and top the reserve up.

A worked example

Say you run a small retail business. Fixed monthly costs come to R85,000, and trade is seasonal, so you sit in the variable category with a 3-month buffer.

R85,000 × 3 = R255,000 reserve target.

If you’re starting from zero, putting aside 10% of monthly revenue, a pace most small businesses can sustain without strangling cash flow, gets you there on a timeframe you can actually plan around, instead of an open-ended “save when you can.”

Where to keep it so it actually works

Keep this reserve out of your everyday operating account. Money you see every time you check your balance is money that quietly gets spent on a slightly-too-tempting opportunity.

A separate business savings account does the job. The funds stay accessible if you genuinely need them, but they’re no longer sitting in the account you dip into for day-to-day spending. This is also why account structure matters as much as the number itself: if your current accounts don’t make that separation easy, it might be worth looking at Access Bank’s tailored business banking solutions

A number, not a guess

R255,000 sounds like a lot until you have a timeframe and a reason behind it. Without those, saving is just one more intention competing against every other use for that cash this month.

This Savings Month, work out your own number. Add up your fixed costs, place your revenue honestly into one of the three categories above, and multiply. Ten minutes, one calculation, and you have a target instead of a habit you keep meaning to start.
