Pay and work
- Take-home pay calculator Brunei 2026In Brunei Darussalam your take-home pay is simple to work out. The Ministry of Finance and Economy says no tax is levied on personal income, so there is no income tax line on your payslip. The only statutory deduction is your share of the national retirement scheme, SPK, at 8.5% of basic salary.
- Hourly to salary calculatorHow much is your salary per hour? What does an hourly offer come to per year? Enter an amount, pick the period and we show all the others.
- Pay raise calculatorYou have been offered a raise, or you are about to ask for one. Enter your pay and the raise, as a percentage or an amount, and see how much changes each month and year.
- Time card calculatorPick the start and end time for each day, your unpaid break and your hourly pay. We show total hours, overtime and your pay for the week.
Taxes
- SPK calculator 2026: TAP and SCP contributionsYou pay 8.5% of your basic salary into the Skim Persaraan Kebangsaan (SPK), the national retirement scheme run by the Employees Trust Fund (TAP). Your employer pays a rate that falls as your salary rises, from 10.5% down to 8.5%.
- Employer cost calculator Brunei 2026Hiring in Brunei Darussalam adds one statutory cost on top of salary: your share of the Skim Persaraan Kebangsaan (SPK). The share depends on the employee's salary group. It is 10.5% for pay up to BND 1,500 and drops to 8.5% above BND 2,800.01.
- Withholding tax calculator Brunei 2026A Brunei company or permanent establishment that pays a non-resident for certain things has to hold back part of the payment and send it to the Collector of Income Tax. The rate depends on what the payment is for. Interest on a loan carries 2.5%. Royalties, know-how, technical services, management fees, rent of movable property and directors' pay carry 10%.
Money and indexes
Money and indexes
- BND to SGD converter 2026: Brunei and Singapore dollarOne Brunei dollar is worth exactly one Singapore dollar. The two countries signed the Currency Interchangeability Agreement in 1967, and the Monetary Authority of Singapore says the currencies can be exchanged at par and without charge. There is no daily rate to look up, so the answer never changes.
- Brunei inflation calculator 2026Prices in Brunei Darussalam have moved slowly. The Department of Economy and Statistics (DEPS) publishes the Consumer Price Index every month, and the latest index is 106.2 for the month starting September 1, 2026.
Loans, savings and investing
- Loan calculatorBefore you sign for a loan, two numbers matter: what you pay each month and what the loan costs you in interest.
- APR to APY calculatorTwo offers with the same rate can cost different amounts. The difference is how often interest is charged or paid.
- Mortgage calculatorA mortgage is the biggest debt most households ever take on. It pays to see the full numbers before you talk to a lender.
- Rent vs buy calculatorComparing the mortgage payment with the rent is not enough. Buyers pay interest, upkeep and property tax, but they end up owning the home. Renters can keep the down payment invested.
- Compound interest calculatorWith compound interest, the interest is added to your balance and starts earning interest of its own. That is why savings grow faster and faster.
- Simple interest calculatorSimple interest is always worked out on the original principal: interest is not added to the balance during the term.
- Savings goal calculatorA trip, a car, a deposit on a home or a cushion for surprises. A goal with an amount and a date is much easier to hit.
- Retirement savings calculatorA state pension often is not enough to keep your standard of living. Savings of your own, even small ones, make a big difference if you start early.
- Credit card payoff calculatorA credit card is usually the most expensive debt you have. Paying only the minimum stretches it out for years and piles on interest.
- 50/30/20 budget calculatorThe 50/30/20 rule is a simple way to plan your month. Half goes to essentials, 30% to things you enjoy and 20% to savings.
- Emergency fund calculatorAn emergency fund is money set aside for what you can't plan for: losing your job, a health problem or an urgent home repair.
- Car cost calculatorMost people know what they spend on fuel. Few add up insurance, maintenance, parking and, above all, the value the car loses every year.
Business and self-employment
- ROI calculatorA 50% gain sounds great, but it is not the same over 2 years as over 10. To compare investments you need the return per year.
- Profit margin calculatorMargin and markup get mixed up all the time, and the difference can cost you money. Both measure the same profit, but against a different base.
- Break-even calculatorThe break-even point is the level of sales where a business neither makes nor loses money. Below it you lose, above it you start to profit.
- Freelance rate calculatorThe most common freelance mistake is taking the salary you would want as an employee and dividing it by 160 hours. That leaves out taxes, expenses, vacation and every hour you can't bill.
Other calculators
- Corporate tax calculator Brunei 2026Brunei Darussalam taxes companies, not people. The corporate income tax rate is 18.5% of chargeable income for the year of assessment 2015 and every later year. The Ministry of Finance and Economy adds a tax threshold that lowers the effective rate for small and medium companies.
- Stamp duty late penalty calculator Brunei 2026Stamp duty in Brunei Darussalam is charged on the documents listed in the First Schedule of the Stamp Act (Chapter 34), such as a tenancy agreement, a share transfer or a conveyance. The Revenue Division assesses the duty. If you stamp late, a penalty is added on top.
- SPK self-employed calculator 2026: Match-UpIf you work for yourself in Brunei Darussalam you can save for retirement in the Skim Persaraan Kebangsaan (SPK), the scheme run by the Employees Trust Fund (TAP). Verified self-employed members get a fixed Government Match-Up of BND 17.50 when they pay in at least BND 17.50 in a month.
- Capital allowance calculator Brunei 2026Depreciation is not a tax deduction in Brunei Darussalam. The Revenue Division replaces it with capital allowances on qualifying capital expenditure. An initial allowance of 20% is given in the year of expenditure, and annual allowances follow.
- Company car tax deduction calculator Brunei 2026A Brunei company that buys a car above BND 50,000 cannot deduct all of its costs. The Income Tax Act limits both the capital allowance and the running costs to the share that BND 50,000 bears to the real price of the car.
