The Finance Algorithm

What we got wrong, and fixed.

Most of the numbers here come straight from banks, insurers, energy retailers and government agencies, and sometimes their data is wrong, or we read it wrongly. When a reader could have seen it, the fix goes here with the date and what changed.

    • Overdraft and business loan tables

      Sorted lowest rate first, they opened with products at 0.00% or 0.01%: placeholders some lenders publish, not rates anyone is charged. Those products now show no rate and sort after the ones that publish one, as the summaries above the tables already did.

    • Super balance projector

      Its retirement chart compared your balance with old ASFA figures: $595,000 for a comfortable retirement as a single and $690,000 as a couple, when the current Retirement Standard says $630,000 and $730,000. It also quoted fee and contribution figures with no source. The chart now uses ASFA's current lump sums, and the unsourced figures are gone.

    • Calculator charts

      Five chart captions didn't match the numbers under them. The 2026-27 tax cut chart said middle incomes save the most, when everyone earning $45,000 or more saves the same $268. The family tax benefit chart gave old income limits ($67k and $117k, now $69,131 and $123,078). The card comparison said points were valued at 0.75c, when it uses the value you enter for each card. The dividend chart said it assumed 5% growth, when it uses your own figure, 4% unless you change it. The super withdrawal chart said withdrawals from 60 are tax-free "up to large amounts"; from a taxed fund they're tax-free in full.

    • Government support finder

      It counted the First Home Guarantee as $10,000 a year and HECS-HELP as $12,000 a year of support. The guarantee is a one-off saving on lenders mortgage insurance when you buy, and HECS-HELP is a loan repaid through tax. Both now say what they are and stay out of the yearly total.

    • Government support finder

      With no support areas ticked, it treated every area as ticked, so its starting figures (a 35-year-old employed citizen on $55,000 with one child) listed nine programs worth about $69,000 a year, including ABSTUDY, which is only for Aboriginal and Torres Strait Islander students, and HECS-HELP. Programs that depend on something the form doesn't ask, such as renting, study, childcare or Indigenous status, now show only when you tick that area, and the starting figures show Family Tax Benefit Part A.

    • Seasonal energy plans

      About one plan in five changes its prices with the seasons, and their headline rates showed the first season only: one NSW plan showed a 20.70c peak rate, its April and May price, when it charges 51.90c from June to August and November to March. Headline rates are now averaged over the year, each season counted for the days it runs, and every season's rates are on the plan's page.

    • Energy hubs

      The lowest and typical usage rates on the energy and electricity pages still counted time-of-use peak rates and wholesale price estimates, so NSW's lowest showed as 15.70c a kWh against 23.80c on the NSW page. Both now count single-rate plans only, as each state's page does.

    • Calculators

      Some fields refused values inside their own limits: the payslip checker wouldn't take $3,000 of gross pay, and a few calculators couldn't be submitted with their own starting figures. Any value between a field's limits is now accepted.

    • Traditional Credit Union

      Its feed gives every rate 100 times too large (14.95 for a 14.95% loan), so its personal loan showed as 1,495% and a 0.01% savings rate as 1.00%, which also put it in the savings rankings. Its products are off the site until the feed is fixed, and any rate above 100% is now rejected for every bank.

    • Bank account and loan fees

      Where a product lists several fees, we added them up. Revolut's personal account showed $146.96 a month, the total of its five plans, when the Standard plan is free. Fee columns now show the main fee, leaving out extras only some customers pay, such as paper statements or legal work.

    • Interest rates today

      The lowest personal loan rate on the banking page was a car loan (Westpac's, at 5.74%). Car loans are now left out there, as they already were from the table beside it.

    • Crypto tax calculator

      A tip said moving coins between your own wallets is a tax event. It isn't; buying, selling, swapping and giving coins away are.

    • Calculator introductions

      Three figures we couldn't source were taken out: a balance at which a self-managed super fund becomes worthwhile, a $100,000 cost of a 0.5% super fee difference, and long-run share returns suggested as a guide.

  3. 16 October 2026

    • Electricity rates

      Plans priced as an estimate, which follow the wholesale market, were being counted as the cheapest in some states. Cheapest-rate answers now compare only single-rate plans with a published price.

    • Personal loan and credit card rates

      Car loans were being counted as personal loans in the lowest-rate answers, and one buy now, pay later product's 1,800 interest-free days was taken at face value. Car loans are now left out of the personal loan figures, and interest-free periods over 62 days are ignored.

    • Fixed home loan rates

      Loans only first home buyers can get led the five-year fixed answer. They're now marked as restricted, like staff and profession loans, so the answer covers loans anyone can apply for.

  4. 13 October 2026

    • Paid Parental Leave estimator

      The daily rate was worked out as the weekly minimum wage divided by five. It's the hourly minimum wage times 7.6 hours, which is how Services Australia sets it.

    • Insurance calculators

      Life, income protection, TPD and trauma calculators showed premium estimates no official source publishes. They now work out the cover you need, and the quote-based tools (car, pet, funeral, landlord) start from the quote you were given.

    • Market figures

      Home value and super figures from paid data providers were replaced with the ABS's lending figures and APRA's super data, or removed.

    • SMSF calculators

      A line said the ATO recommends at least $200,000 to start a self-managed super fund. The ATO sets no minimum, and neither does ASIC's Moneysmart, so the line now says that.

  5. 11 October 2026

    • HECS-HELP calculator

      It said salary-sacrificed super doesn't count towards your repayment income; it does. It also said lenders look at your HECS balance, when what they count is the repayment.

  6. 9 October 2026

    • Budgeting calculators

      Four calculators were named after real budgeting apps and described features those apps don't have. They've been removed.
