Loan EMI Calculator

How to use the loan EMI calculator

Enter the loan amount

The principal — how much you're borrowing. Type the number without thousand separators (the tool adds those when displaying results). Switch currency to match your loan; the calculation works the same way in any currency.

Enter the annual interest rate

Use the advertised rate from your lender (e.g. 6.5% for a personal loan, 3.2% for a home loan, 7.99% for an unsecured loan). Most APAC consumer loans use reducing-balance rates — that's what this calculator assumes. Avoid flat rate (sometimes called add-on rate) since it's typically 1.7-2× more expensive in real terms.

Set the term

How long you'll be repaying — in years (typical for car/home loans) or months (typical for short personal loans). Longer term = lower monthly EMI but more total interest. Use the 25-year mortgage preset to see how much interest stacks up on long loans.

Read the amortisation schedule

Below the summary cards, you'll see a month-by-month (or year-by-year for long loans) breakdown of how each EMI splits between principal repayment and interest. Notice how in the early years almost all of the EMI is interest — that's normal for reducing-balance loans.

EMI — the mathematics behind your monthly repayment

EMI ("Equated Monthly Instalment") is the fixed amount you pay every month for the life of a loan. The same amount goes out of your account every month — but what changes invisibly is the split inside that payment. In the first month, most of your EMI is interest on the still-large balance and very little goes to principal. By the final month, the balance is small, almost all of your EMI is principal, and the interest portion is tiny. The total stays constant because the interest declining is exactly balanced by the principal rising. This is the genius of the reducing-balance method — it's why your monthly outflow doesn't change even though your debt is shrinking.

The formula (it's not magic)

EMI is calculated using a single equation: E = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1). Where P is the principal (loan amount), r is the monthly interest rate (annual rate divided by 12 and then by 100 to convert from percent to decimal), and n is the total number of months. The formula comes from the requirement that the future value of all EMIs (discounted back to present) equals the original principal. Spreadsheets call this the PMT() function and bankers across the world use the same equation. Every legitimate EMI calculator gives identical results to the cent — if a calculator gives a different number, it's either using flat-rate (banned in most markets for consumer loans), adding hidden fees into the EMI, or wrong.

On a S$500,000 mortgage at 3.2% over 25 years, you pay back S$726,000 — meaning S$226,000 is interest. That's 45% of your principal added on top.

Reducing-balance vs flat rate — know which you're being quoted

Reducing-balance is the standard and the only fair method. Interest is calculated each month on the remaining (declining) balance. Flat rate is the older, predatory alternative — interest is calculated on the original full loan amount for every month of the term. A 5% flat rate loan over 5 years is roughly equivalent to a 9% reducing-balance loan — almost double. Singapore, Malaysia, Australia, Hong Kong require reducing-balance for consumer credit. India still permits flat-rate for some specific products (commercial vehicle loans, microfinance). Indonesia, Philippines, Thailand, Vietnam: mix. If a lender advertises a "low rate" but the EMI seems high — they may be quoting flat. Always ask for the effective reducing-balance rate.

The APAC consumer-credit landscape

Loan markets across APAC vary widely in pricing, accessibility, and underlying interest-rate environment. Singapore personal loans run 5-9% reducing-balance; home loans 3.0-3.8% (most pegged to SORA). Hong Kong personal loans 4-12%, home loans 3.5-4.5% (HIBOR-pegged). Malaysia personal loans 5-15% with strong tiering by income; home loans 3.5-5%. Indonesia sees personal loan rates of 12-30% (regulated cap 36%/month for digital lenders); KPR home loans 7-12%. Philippines personal loans 1.5-3% per MONTH on flat-rate quotes (~18-36% reducing). Thailand personal loans capped at 25% per year; home loans 5-7%. Vietnam personal loans 12-22%, home loans 8-12%. India personal loans 10-24%, home loans 8-9.5% (mostly RLLR-linked). Japan personal loans 1-15% (huge spread), home loans 0.5-1.5% (some of the lowest in the world). South Korea personal 4-15%, home 3.5-5.5%. China personal 4-18%, home 4-5.5% (LPR-linked). Australia personal 7-20%, home 5.5-7%. Across the region, the pattern holds: home loans cluster around the country's policy rate; personal/unsecured loans add a large risk premium. Use this calculator for any of these — the math is identical.

What this calculator doesn't show

It doesn't include the upfront processing fee (typically 1-3% of the loan, deducted from disbursement), the insurance/protection plan sometimes bundled (effectively raising your real rate by 0.5-1.5%), early-repayment penalties (common on home and car loans for the first 3-5 years), late-payment charges, or the annualised percentage rate (APR) which includes all of the above. The EMI shown here is the pure interest-rate math; for an apples-to-apples comparison between lenders, ask each for the APR. Two loans with identical EMIs can have very different total costs once fees are folded in.

10 Things You Didn't Know About Loans

01

The EMI formula was derived in the 17th century from the same compound-interest math that powers actuarial science.

02

Microsoft Excel's PMT() function uses the EMI formula and has returned identical values since 1985 — unchanged for 40 years.

03

The earliest known fixed-instalment loan with a documented amortisation table is a 1789 French government bond paying livres in monthly tranches.

04

Japan's home loan rates dropped below 1% in 2016 and have stayed there — a 0.5% home loan is currently common for prime borrowers.

05

Singapore's SORA (Singapore Overnight Rate Average) replaced SIBOR in 2024 as the benchmark for most floating-rate home loans.

06

India's Reserve Bank moved consumer loans to "external benchmark linked" (RLLR/EBLR) in 2019 — making rate-cuts pass through to borrowers within 3 months.

07

Indonesia caps consumer digital lending at 0.4%/day total cost (interest + fees) under OJK Regulation 22/2023 — about 144%/year max.

08

The Philippines' Truth in Lending Act (2001) requires lenders to disclose the EIR (Effective Interest Rate) — the closest local equivalent to APR.

09

Australia banned "flat rate" advertising for consumer loans in 2003 — all rates must be quoted as the comparable reducing-balance equivalent.

10

Hong Kong's HIBOR-pegged home loans typically adjust monthly, while Singapore's SORA loans adjust every 3 months — a borrower-protection trade-off.

FAQ

EMI (reducing-balance) calculates interest each month on the declining outstanding balance — fair to the borrower. Flat-rate calculates interest on the original full loan amount for every month — typically results in ~1.7-2× the true interest cost of an equivalent reducing-balance loan. Always prefer reducing-balance.
Yes for the pure interest math — every reducing-balance EMI calculator uses the same formula. Differences arise from fees the bank adds (processing fee, insurance, late-payment buffer) which aren't shown here. Ask your lender for the APR for a full apples-to-apples comparison.
Yes — every dollar of principal you prepay reduces the balance, so future interest calculations are lower. Most loans permit prepayment but charge penalties (typically 1-3% of the prepaid amount) within the first 3-5 years. Check your loan agreement.
Because in month 1, the balance is at its largest, so interest (= balance × rate) is at its largest too. EMI is fixed, so what's left after interest = principal portion = small. As the balance shrinks each month, the interest portion shrinks and the principal portion grows.
Depends heavily on country and credit profile. Rough good-rates: Singapore 5-7%, Malaysia 6-10%, Hong Kong 4-8%, India 10-14%, Indonesia 12-18%, Philippines 12-20%, Thailand 12-18%, Australia 7-12%, Japan 2-5%. Below these is excellent; above these, shop around.
Same math, different rate. Car loans are secured by the vehicle so rates are 1-2% lower than personal loans (typically 3-6% in Singapore/Malaysia/Australia, 7-12% in India/Indonesia). Term is usually 5-9 years. Watch for residual value / balloon-payment structures which keep monthly low but require a big final payment.
It depends on what you optimise for. Longer term = lower monthly cash outflow = more comfortable monthly budget — but significantly more total interest paid. A 25-year mortgage costs roughly 2× the interest of a 15-year mortgage at the same rate. Pick term to match your stable monthly cashflow, not the lowest possible EMI.
Yes — the math is identical regardless of loan type. For SG-specific mortgage calculation including HDB/BTO scenarios and CPF deductions, use our Mortgage Calculator instead.
This tool assumes a fixed rate for the full term. For variable-rate loans (SORA-linked in Singapore, HIBOR in Hong Kong, RLLR in India), calculate with the current rate as a baseline, then recalculate if rates change significantly. Most APAC home loans are floating-rate.
