Running a small or medium business in Australia means making financial decisions every week that directly affect profitability, compliance, and growth. From pricing products correctly to understanding whether you can afford your next hire, each decision benefits from actual numbers rather than gut feel.
Australian business owners spend an average of 10 to 15 hours per month on manual calculations and spreadsheet work. These hours cost real money, and the errors that come with manual work cost even more. A single BAS error can trigger ATO penalties starting at $330 per 28-day period. An underpriced product can quietly drain your margin for months before you notice.
Scale Suite has built a comprehensive suite of free business calculators designed specifically for Australian SMEs. Every tool is ATO-compliant where relevant, takes seconds to use, and requires no registration or email sign-up.
Here is the full toolkit, organised by the business decision each tool supports.
Add or remove 10% GST from any amount. Use it when creating quotes, verifying invoice totals, or checking figures before lodging your BAS. Handles both GST-inclusive and GST-exclusive calculations.
Estimate GST on international transactions including GST-free export status, import liabilities, and input tax credits. Essential for businesses trading across borders.
Estimate your net GST using the three-field Simpler BAS method (G1, 1A, 1B) for businesses with GST turnover under $10 million. Ideal for quarterly BAS preparation.
Enter your turnover, reporting frequency, and lodgement method to get personalised BAS due dates for the full financial year. Includes registered agent concession dates.
Interactive 35-point pre-lodgement checklist covering GST, PAYG withholding, PAYG instalments, bank reconciliation, and review checks. Progress saves automatically.
Quick assessment of your overall ATO compliance position across GST, payroll, super, and record-keeping obligations. Identifies gaps before the ATO does.
Enter your total wages and select your state to see whether you exceed the payroll tax threshold and estimate your liability. Covers all states and territories.
Calculate employer super obligations at the current 12% rate based on ordinary time earnings. Helps with quarterly cash flow planning around super payment deadlines.
Enter a base salary and see the true total cost including super, payroll tax, leave entitlements, workers' compensation, recruitment, equipment, and management overhead. That $80,000 salary actually costs your business $105,000 or more.
Compare the fully loaded cost of an internal hire against outsourcing to Scale Suite. Shows the cost difference and potential savings across different salary levels.
Interactive tool that walks you through a series of questions about your business needs and recommends whether hiring or outsourcing makes more sense for your situation.
Enter your revenue, expenses, and the proposed salary to see whether the hire is financially viable based on your current margins and cash position.
Analyses your revenue trajectory and workload to suggest the right timing for your next hire.
Compare the cost of engaging a contractor versus employing someone directly. Includes super, payroll tax, leave, and classification considerations.
Estimate total hiring costs including agency fees, job advertising, internal time, and onboarding expenses across different recruitment channels.
Calculate the financial impact of losing and replacing an employee. Most businesses underestimate this figure, which typically ranges from 50% to 200% of the departing employee's salary.
Calculate your annualised turnover rate and compare it against Australian industry benchmarks.
Calculate gross and net profit margins for your products or services. Helps ensure your pricing strategy covers costs and delivers healthy margins.
Determine exactly how many units you need to sell (or how much revenue you need) to cover all fixed and variable costs. Essential for new product launches and business planning.
Enter project revenue, direct costs, and allocated overheads to determine true profitability at the project level. Critical for service businesses that need to understand which clients and projects are actually making money.
Input your costs, desired margin, and market positioning to generate a recommended price point. Takes the guesswork out of pricing decisions.
Rank your clients by profitability factoring in revenue, time invested, and direct costs. Identifies which clients are worth growing and which are worth exiting.
Project your cash position over the coming months based on expected inflows and outflows. Helps identify cash shortfalls before they become crises.
Enter your current cash balance and monthly burn rate to see your cash runway. A confronting but essential calculation for any business watching its cash position.
Quick assessment across key financial metrics including profitability, liquidity, efficiency, and growth. Gives you a snapshot of where your business stands.
Estimate what your business might be worth using revenue and earnings multiples. Useful for exit planning, investor conversations, or simply understanding the value you are building.
Calculate how much it costs to acquire a new customer across different marketing channels. Essential for evaluating whether your marketing spend is sustainable.
Estimate the total revenue a customer generates over their entire relationship with your business. The ratio of LTV to CAC determines whether your growth model is viable.
Interactive checklist covering every step of onboarding a new employee in Australia, from TFN declarations and super choice forms to IT setup and induction training.
Create professional, ATO-compliant tax invoices with automatic GST calculations and PDF export. Includes all mandatory fields for invoices over $82.50. See our detailed invoicing guide for best practices.
Generate tailored interview question guides based on role type, seniority level, and desired competencies. Helps structure consistent, effective hiring processes.
Accurate numbers prevent three of the most common (and expensive) SME mistakes.
Compliance errors trigger ATO penalties. Incorrect GST calculations, late BAS lodgement, or miscalculated PAYG withholding attract penalties starting at $330 per 28-day period for small entities, plus General Interest Charge at approximately 11% per annum on any underpayment.
Poor hiring decisions waste $40,000 to $160,000. Hiring when you cannot afford it, hiring at the wrong level, or underestimating the true cost of employment are among the most expensive mistakes a growing SME can make.
Incorrect pricing destroys margin silently. If your pricing does not cover all costs (including overheads most owners forget), you can be busy and broke simultaneously. The break-even calculator and profit margin calculator catch this before it compounds.
Every calculator on this page is completely free with no email gates, no account creation, and no hidden upsells. We built these tools because informed business owners make better decisions, and better-run businesses are better clients.
