Bank Loan Calculator Singapore

What Is a Bank Loan Calculator Singapore?

A Bank Loan Calculator Singapore estimates the monthly instalment, total interest and scheduled repayment for a loan.

You can compare a monthly-rest loan with a flat-rate loan using the same amount, advertised rate and tenure. The result is an estimate based on the information entered.

You can find other locally focused finance tools on the Calculator Singapores homepage.

What Does the Calculator Show?

The calculator displays:

• Estimated monthly instalment
• Total interest
• Total scheduled repayment
• Principal, rate and tenure
• Selected interest method
• First-month interest and principal for monthly-rest loans
• Repayment plus the entered upfront fee

The main Total Repayment result excludes the optional upfront fee. The detailed breakdown shows scheduled repayments plus the fee.

How to Use the Bank Loan Calculator

1. Enter the Loan Amount

Enter the amount you plan to borrow in Singapore dollars.

Use the principal amount before adding interest or fees. The value must be greater than S$0.

A company seeking financing can use the Singapore Corporate Business Loan Calculator for a business-focused repayment estimate.

2. Enter the Advertised Interest Rate

Enter the advertised annual interest rate as a percentage.

For example, enter 3.5 for a rate of 3.5% per annum.

The calculator accepts rates from 0% to 100%. It assumes the entered rate remains unchanged throughout the loan.

3. Enter the Loan Tenure

Enter the repayment period in whole years.

The calculator accepts a tenure from 1 to 40 years. It converts the entered tenure into monthly payments.

4. Select the Interest Method

Choose:

• Monthly Rest/Reducing Balance
• Flat Rate

The same advertised rate can produce different borrowing costs under these two methods.

5. Enter an Upfront Fee

Enter any known processing or other upfront fee.

Leave the field at zero if no fee applies. The calculator adds the fee to the all-in cost shown in its breakdown but does not spread it across the monthly instalments.

The Singapore Tax Calculator performs tax estimates, not borrowing-cost calculations. Loan interest and fees should not be treated as taxes.

6. Select Calculate Loan

The result shows the estimated instalment, interest and repayment.

Select Reset to clear all entries and return to the monthly-rest method.

Monthly-Rest Loan Formula

With monthly-rest or reducing-balance interest, each month’s interest is based on the outstanding principal.

The calculator uses:

Monthly payment = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)

Where:

• P is the loan principal
• r is the monthly interest rate
• n is the number of monthly payments

The monthly rate is:

Monthly rate = Annual rate ÷ 12

Each instalment contains principal and interest. The interest portion normally falls as the outstanding balance reduces.

If the entered annual rate is 0%, the calculator divides the principal equally across all months.

Flat-Rate Loan Formula

With a flat-rate loan, interest is calculated using the original principal for the full tenure.

Total interest = Principal × Annual rate × Number of years

Total repayment = Principal + Total interest

Monthly instalment = Total repayment ÷ Number of months

A flat advertised rate normally produces a higher effective borrowing cost than an identical monthly-rest rate because interest continues to be based on the original principal.

Bank Loan Calculation Example

Assume:

• Loan amount: S$100,000
• Advertised rate: 3.5% per year
• Tenure: 5 years
• Method: Monthly Rest/Reducing Balance
• Upfront fee: S$500

There are 60 monthly payments.

The monthly rate is:

3.5% ÷ 12 = 0.2917%

Using the monthly-rest formula, the estimated monthly instalment is:

S$1,819.17

The estimated results are:

• Monthly instalment: S$1,819.17
• Total interest: S$9,150.47
• Total scheduled repayment: S$109,150.47
• Repayment plus fee: S$109,650.47

The first month’s estimated interest is S$291.67. About S$1,527.51 of the first payment goes towards principal.

Later payments normally contain less interest and more principal, assuming the rate remains unchanged.

Flat Rate vs Monthly Rest

A monthly-rest loan calculates interest on the reducing outstanding balance.

A flat-rate loan calculates interest on the original amount for the full tenure. For this reason, comparing advertised percentages alone can be misleading.

The effective interest rate, or EIR, helps compare the real borrowing cost. MoneySense explains that fees, repayment frequency and the calculation method can affect EIR.

This calculator does not convert the entered fee into a regulatory EIR. Ask the bank for the official EIR and repayment schedule before accepting an offer.

Can the Calculator Check Loan Eligibility?

No. It estimates repayment amounts but does not assess whether a bank will approve an application.

The Loan Eligibility Calculator Singapore provides a separate affordability estimate using its own inputs. Actual approval still depends on the lender’s checks and policies.

Banks may consider income, existing debts, credit history, age, collateral, loan purpose and other information.

Fees and Other Loan Costs

The optional fee field helps show that upfront charges increase the total cost of borrowing.

Actual loan costs may also include:

• Processing fees
• Legal or valuation fees
• Late-payment charges
• Cancellation fees
• Early-repayment charges
• Insurance
• Rate-conversion charges

The calculator does not automatically include these costs. Enter only a known upfront fee and review the lender’s documents for other charges.

Keep Unrelated Calculations Separate

A loan amount is different from the value of an asset being purchased.

The Gold Price Calculator Singapore estimates gold value. It does not determine whether borrowing to purchase gold is affordable or suitable.

GST and service charge are also separate from loan interest. The Singapore Service Charge And GST Calculator estimates charges on a bill, not bank-loan instalments.

The Faraid Calculator Singapore estimates the estate remaining after entered expenses, debts and religious obligations. It does not calculate loan repayments or determine beneficiaries’ inheritance shares.

What the Calculator Cannot Determine

The calculator cannot determine:

• Whether a lender will approve the loan
• The official EIR
• Future floating-rate changes
• Late-payment or early-settlement charges
• Loan insurance costs
• Redraw or refinancing terms
• Whether interest is tax-deductible
• The lender’s exact repayment schedule

For a floating-rate loan, the estimate assumes the entered rate remains unchanged for the entire tenure.

Common Loan Calculation Mistakes

Comparing Advertised Rates Only

A 3% flat rate is not equal to a 3% monthly-rest rate. Compare the official EIR and total repayment.

Ignoring Fees

A lower advertised rate may still have a higher all-in cost after processing and other charges.

Choosing a Long Tenure Only for a Lower Instalment

A longer tenure may reduce the monthly payment but usually increases total interest.

Entering Months Instead of Years

The tenure field accepts whole years. Enter 5 for a five-year loan, not 60.

Assuming a Floating Rate Will Stay Fixed

The calculator uses one rate for the full calculation. Actual payments may change when a floating rate changes.

Treating the Estimate as a Bank Offer

The result does not guarantee approval, interest rate, repayment amount or loan terms.

Frequently Asked Questions

Q1: What does the bank loan calculator calculate?

A: It estimates the monthly instalment, total interest and scheduled repayment from the loan amount, rate, tenure and interest method.

Q2: What is a monthly-rest loan?

A: Interest is calculated on the outstanding balance. The interest portion normally falls as the principal is repaid.

Q3: What is a flat-rate loan?

A: Interest is calculated on the original principal for the full tenure, even as the balance is repaid.

Q4: Does the monthly instalment include the upfront fee?

A: No. The fee is shown separately in the all-in borrowing-cost breakdown.

Q5: Does the calculator show EIR?

A: No. It does not convert the rate and fees into a regulatory EIR.

Q6: Can it check whether I qualify for a loan?

A: No. It calculates repayment estimates and does not assess approval eligibility.

Q7: Can I use a floating interest rate?

A: You can enter the current rate, but the calculator assumes that rate stays unchanged for the full tenure.

Q8: Is the result the final repayment quoted by a bank?

A: No. Confirm the final instalment, fees, repayment schedule and EIR with the lender.
