How it works

Clear calculations.
No black box.

interest.sg connects inputs, rules, results and source references in one understandable path.

Choose one financial question

Start with the calculator closest to the decision in front of you—not a long, generic questionnaire.

Add inputs you can verify

The page separates your values from rule settings and shows how each input is used.

Read the result and its limits

Key figures, applied limits, assumptions, liquidity conditions and sources appear in one view.

Save or download

Once accounts and reports are connected, calculations can be saved and exported as dated summaries.

Platform boundary

Information and calculation—not personalised financial advice.

The tools help people understand how figures change. The platform is not a bank, broker, trading platform or government body, and it does not promise outcomes.

Start with one question

Explore all 14 financial tools.

Preview the scope, inputs, outputs and primary source for every tool.
