What the Altitude Platinum Card calculator works out

This is an interactive calculator for the Altitude Platinum Card. It estimates how many Westpac Altitude Rewards Points the card earns from your own spending, what those points are worth at a valuation you set, and what the card is worth across a year once benefits and the annual fee are accounted for. The figures below are the card's published rates; enter your spending to replace them with your own numbers.

Altitude Platinum Card earning rates

The calculator applies these rates to the spending you enter, dropping to the lower rate automatically once a cap is reached.

Example: Altitude Platinum Card earnings on International Purchases

Putting $1,000 a month into International Purchases ($12,000 a year) with the Altitude Platinum Card earns about 24,000 Westpac Altitude Rewards Points a year. At a baseline of 0.44¢–0.65¢ per point, that's about $106.19–$156 in value, against $175 in annual fee. You can set your own value per point in the calculator. Change the spending figures to work this out for your own budget across every category at once.

How the Altitude Platinum Card result is calculated

Net annual value = (Westpac Altitude Rewards Points earned from your spending × your value per point) + the value you assign to the card's credits and benefits − the $175 annual fee.

Westpac Altitude Rewards Points start at a baseline of 0.44¢–0.65¢ each. That figure is a starting point, not a fixed rate — the calculator lets you replace it with your own.

Every input is adjustable: spending per category, the value of a single point, what each credit or benefit is worth to you, and whether to count the intro bonus. Up to 10 cards or multi-card wallets can be compared side by side, and each card can be set to earn a different rewards currency, including any of the 6 programs Westpac Altitude Rewards Points transfer to — so a card can be valued at what its points are worth after a transfer rather than at the baseline rate.

How This Credit Card Rewards Calculator Works

This tool uses a Net Value framework to estimate what you earn minus the costs of holding the card, based on your inputs.

The formula: Net Value = ((Rewards Earned from Spend × Value per points) + Perk Value) − (Annual Fee + Foreign Transaction Fees)
If you include intro bonuses in the calculator, they're added to annual value using the same points valuation you set.
Total customization: Baseline estimates may pre-fill for convenience, but you can override values (valuations, spend, perks, and fees) to match your strategy.
Transfer modeling: For transferable rewards, conversions are modeled using standard ratios for your region. You can adjust ratios to reflect transfer bonuses or recent changes.
Verified rates: Default earning multipliers and fees are based on current issuer/program terms, then your calculator inputs determine the final result.
