For a residential property estimate, basic Buyer’s Stamp Duty uses the higher of the purchase price and market value. Additional Buyer’s Stamp Duty is outside the tool and must be checked separately.
Compare the same costs and time period
The GST calculator covers standard-rated prices only. Keep CPF contributions, housing costs and taxes separate from general SGD budget and savings projections; these tools do not calculate those obligations.
Fixed-rate loan payment in SGD
Enter your own amount and nominal annual rate. This general formula assumes equal monthly payments and excludes fees, insurance, taxes, variable rates and product-specific contract rules.
Worked example: $20,000.00 at an assumed 6% nominal annual rate over 36 months gives $608.44 per month. This rate is an example, not a Singapore market rate or offer.
Formula: payment = P × r / (1 − (1+r)−n), where r is the annual percentage divided by 1200 and n is months. At zero interest, payment = P/n. Use the full loan calculator.

Planned local coverage
These tools are coming soon and are not available as calculations:
- net salary
- CPF
Each needs its own official sources, supported circumstances and test cases before publication.
Before you compare results
Keep the currency and time period consistent. A monthly income estimate is an annual average unless the calculator explicitly models individual pay periods. The general loan and savings tools do not apply Singapore tax law, fees, benefit rules or investment guarantees.
Changing the display currency does not convert exchange rates or change the legal jurisdiction of a calculator. Use the dedicated local tool for the scope described above.
