Start with these questions

Car budget and alternatives

Gather the purchase price, financing terms, running costs and expected holding period.

Buying or moving home

Gather income, debts, purchase price, cash/CPF balances and the sale or purchase timeline.

Loans, interest and duties

Use actual balances, rates, fees and dates. Separate interest savings from changes to monthly cash payments.

Care and household support

Keep paid costs separate from the value assigned to family time, and include backup care.

Protection gaps

Gather household spending, debts, existing cover and the period support may be needed.

Surplus cash and retirement

Compare the purpose, access restrictions and assumptions behind each allocation.

Read the result before acting on it

Cashflow: when money is paid or received, including loan repayments and deposits.
Total cost: what the model counts as consumed over the selected period. Check how it treats principal and residual value.
Net worth: assets less liabilities under the model’s future-value assumptions.
Time burden: family hours multiplied by an assumed value are not necessarily a cash bill.

Read the individual tool to see which measure it uses. The directory does not mean every model includes every fee, eligibility rule or personal circumstance.

Keep the sensitivity check simple

Save the inputs and result from your base case. Change one uncertain input, then test several adverse changes together if they could happen at the same time. A result is useful when you can explain why it changes.

In a hypothetical cost comparison, option A costs S$1,200 a month and option B S$1,050: a S$150 monthly difference. If switching costs S$1,800, it takes 12 months to recover that fee, before financing, timing or other differences. A six-month commitment would not recover it from that saving alone.

Obtain actual quotes and check current rules before a purchase, application or change in cover. Tool defaults are starting assumptions, not personal recommendations or guaranteed outcomes.

Frequently asked questions

Are the default figures a recommendation for my household?

No. Replace defaults with your own figures and read the assumptions. Verify current quotes, rules and eligibility before acting.

Why can two tools produce different results?

They may answer different questions or use different horizons, cash-flow treatment and future-value assumptions. Compare the definitions and inputs first.

Are all tools in this directory newly reviewed?

No. The directory was reviewed on the date below. Each tool has its own review date and limitations; its inclusion here does not change those.

Can I use a calculator result as an approval or quote?

No. A planning estimate is not a lender decision, insurance quotation or confirmation of tax treatment.
