As a contractor your income can fluctuate, making a disciplined savings strategy essential. This calculator helps you see exactly how much is left after living costs and lets you split the surplus between an accessible current account and a long-term compounding investment.

Frequently Asked Questions

Why split savings into current and long-term?

Current savings act as a buffer for short-term needs like tax bills, equipment purchases, and gaps between contracts. Long-term savings are invested for growth — compounding works best when you don't withdraw. Keeping them separate removes the temptation to dip into your future.

What interest rate should I use?

The default 3.6% reflects a conservative real return after inflation. High-interest savings accounts in Australia typically offer 4–5% nominal, while diversified index funds have historically returned 7–10% before inflation. Adjust the rate to match your investment vehicle.

How much should contractors save each month?

A common guideline is to save at least 20% of gross income — split between an emergency buffer (3–6 months of expenses) and longer-term wealth building. Contractors should aim higher because income is irregular.

Does this calculator account for tax?

No. Enter your after-tax (take-home) monthly income. Tax obligations should be set aside separately before you calculate disposable income.
