Business Term Deposit Calculator Australia (2026)

A business term deposit is a fixed-rate, fixed-term cash placement product for company, trust or sole-trader funds. Mechanically similar to retail term deposits but with different tax treatment, larger typical balances, and more nuanced fit within a business's overall cash management strategy.

How business TDs work

You deposit a lump sum (typical minimum $5,000–$10,000) for a defined term — 1 month to 5 years. The bank pays a fixed rate over the term. At maturity you receive principal plus interest, or interest is paid periodically along the way for terms ≥12 months.

Most business TDs offer:

Online application (smaller amounts) or branch/manager (larger, $100k+)
Same Financial Claims Scheme guarantee as personal deposits ($250k per ADI)
Standard early break penalties (same as retail)

Tax treatment

Interest is assessable business income, taxed at the business's marginal rate:

Companies: 25% (base rate entity, turnover < $50m) or 30% (full rate)
Trusts: distributed to beneficiaries and taxed at their rates
Sole traders: taxed as personal income at the owner's marginal rate
SMSFs: 15% in accumulation phase, 0% in pension phase

The 25% company rate is meaningfully better than top personal marginal rates (47%), so businesses often have an advantage on after-tax yield versus the same amount held personally.

Where business TDs fit in the cash stack

A typical SME cash stack:

Operating account — daily working capital, no interest or minimal
Cash management account (CMA) — accessible savings buffer, variable rate ~3–4% in current environment
Term deposits — defined-date use cases (tax payments, BAS, anticipated capex)
Loans — when cash is short, borrowing fills gaps

The decision tree:

Need access at any time? → CMA
Specific date use case (tax, capex, payroll)? → TD with maturity matched to that date
Surplus cash with no near-term use? → split between CMA and laddered TDs

Laddering for liquidity + protection

For larger business cash positions ($500k+), laddering across multiple TDs and multiple ADIs achieves two things:

FCS guarantee protection — staying ≤$250k per ADI keeps everything government-guaranteed
Rolling liquidity — a portion matures periodically without breaking long-term TDs

Example with $1.2m surplus:

$250k in 6-month TD at Bank A
$250k in 12-month TD at Bank B
$250k in 18-month TD at Bank C
$250k in 24-month TD at Bank A (different account so doesn't aggregate)
$200k in CMA at Bank D for working capital

Every 6 months, ~$250k matures and can be rolled into a new term or spent. Maximum FCS protection. Spread duration risk across the rate cycle.

When TDs aren't the right move for business cash

Cases where alternatives win:

Outstanding business debt with rate higher than TD rate — pay down the debt instead (see refinance calculator)
Imminent capex or major working capital need — keep in CMA for accessibility
Investment-grade fixed income alternatives (corporate bonds, hybrid securities) — for businesses with treasury sophistication and >$5m surplus
Equity in your own business — if your business returns 15%+ ROE, internal reinvestment beats a 5% TD

For most SMEs, a simple stack of operating account + CMA + occasional TD is the right structure. The calculator above models the TD piece.

Frequently asked questions

Is interest on business term deposits taxed?

Yes. Interest is assessable income to the business at the company tax rate (25%–30% depending on size and turnover) or the relevant rate for trusts and other structures. Sole trader business TD interest is taxed at the individual's marginal rate. Tax is paid via the business's annual income tax return.

Are business term deposits covered by the FCS guarantee?

Yes — same as personal deposits. The Financial Claims Scheme guarantees up to $250,000 per account holder per ADI. For a business, the company itself is treated as one account holder, so $250k is the cap per ADI. Splitting a large business deposit across multiple ADIs is the simplest way to stay within guarantee.

What's the difference between a business TD and a cash management account?

Term deposits lock funds for a fixed term at a fixed rate. Cash management accounts (CMAs) are accessible at-call savings products with variable rates, typically used by professional services firms, investors, and SMSFs. CMAs offer better liquidity but lower rates than TDs in most environments. Choose based on whether you need access during the term.

Should I split my business cash across multiple TDs?

Two reasons to ladder: (1) FCS guarantee limit ($250k per ADI), and (2) liquidity laddering — staggered maturity dates so part of the cash is becoming available periodically. For a $1m business cash position, splitting across 3 ADIs in $250k–$300k tranches with staggered terms (3 months, 12 months, 24 months) gives you both protection and rolling access.

Are term deposits a good fit for SMSFs?

Yes — term deposits are a defensive asset class that fits well in conservative or balanced SMSF allocations. SMSF interest is taxed at 15% in accumulation phase or 0% in pension phase, so the after-tax yield in pension phase can be higher than in a personal account. Discuss SMSF asset allocation with your adviser.

What's the early break penalty on a business TD?

Same as retail TDs — typically a 0.50%–2.50% reduction in the interest rate, plus 31 days' notice required at most banks. Penalty often eliminates interest earned to date. Treat business TDs as locked away; only deposit money you're confident the business won't need during the term.

Is a TD better than paying down a business loan early?

Compare after-tax yields. If your business loan is at 7% and your TD is at 5%, paying down the loan effectively returns 7% (loan rate) tax-free, while the TD returns 5% pre-tax (~3.5% after company tax). Loan paydown wins at most current rates. Term deposits make sense when you have surplus cash with a defined-date use, OR when you need to maintain working capital flexibility (loan repayments are not redrawable in many facilities).
