Singapore Divorce Maintenance Calculator

What Is a Singapore Divorce Maintenance Calculator?

The Singapore Divorce Maintenance Calculator provides a neutral budgeting estimate for child and spousal maintenance discussions.

Enter the number of children, their reasonable monthly expenses and the available monthly resources of both parents.

The calculator compares how the child expenses could be shared in proportion to the entered resources.

You may also enter a monthly spousal need or shortfall for separate review.

The result is not a recommended court award. Singapore courts do not use a fixed maintenance percentage or a universal online formula.

How to Use the Calculator

Enter the number of children included in the calculation.

Next, enter their total reasonable monthly expenses. Use one combined amount for all children rather than the expense for only one child.

Enter Parent A’s monthly income or available resources.

Then enter Parent B’s monthly income or available resources.

If there is a possible monthly spousal need or shortfall to discuss, enter it in the optional final field. Enter zero when you do not want to include this planning figure.

Select Calculate Planning Estimate to view the comparison.

Use Reset before checking another scenario.

What Child Expenses Can Be Included?

Use reasonable recurring expenses connected with the children’s needs.

These may include:

• food;
• the children’s share of housing costs;
• clothing;
• childcare;
• school expenses;
• transport;
• healthcare; and
• other necessary recurring costs.

Avoid automatically including every household expense in full.

Keep invoices, account statements and receipts where available. Exceptional medical, educational or other large expenses may require separate evidence and discussion.

Restaurant service charge and GST should not be treated automatically as a child-maintenance category. Use the Singapore Service Charge and GST Calculator only when checking the total of an actual bill.

Child Expense Allocation Formula

This calculator uses a proportional budgeting comparison.

First, it combines the entered resources:

Combined resources = Parent A resources + Parent B resources

It then estimates each parent’s proportion:

Parent A proportion = Parent A resources ÷ Combined resources

Parent B proportion = Parent B resources ÷ Combined resources

The child-expense comparison is:

Parent A estimated share = Total child expenses × Parent A proportion

Parent B estimated share = Total child expenses × Parent B proportion

The per-child expense is:

Expense per child = Total child expenses ÷ Number of children

This is a mathematical budgeting model. Proportional income sharing is not a guaranteed legal formula.

Divorce Maintenance Calculation Example

Suppose the following amounts are entered:

• number of children: 2;
• total monthly child expenses: S$1,800;
• Parent A’s available resources: S$5,000; and
• Parent B’s available resources: S$7,000.

Combined monthly resources are:

S$5,000 + S$7,000 = S$12,000

Parent A’s proportion is:

S$5,000 ÷ S$12,000 = 41.67%

Parent B’s proportion is:

S$7,000 ÷ S$12,000 = 58.33%

The neutral child-expense comparison becomes:

Parent A: S$1,800 × 41.67% = S$750

Parent B: S$1,800 × 58.33% = S$1,050

The monthly expense per child is:

S$1,800 ÷ 2 = S$900

These figures do not mean that Parent A must pay Parent B S$750 or that Parent B must pay S$1,050.

The calculator does not know which expenses each parent already pays directly, where the children live, the care arrangements or the facts a court would consider.

How Spousal Shortfall Is Treated

The monthly spousal-needs field is an optional planning input.

If you enter S$500, the calculator can show S$500 as an amount requiring separate review. It does not calculate that amount from the parents’ incomes or automatically add it to either parent’s child-expense share.

Spousal maintenance depends on the individual circumstances of the case.

Relevant matters can include financial needs, income, earning capacity, age, health, the duration of the marriage, the standard of living during the marriage and the division of matrimonial assets.

Do not enter an amount merely because one spouse earns less. Prepare a realistic monthly budget and obtain legal advice where needed.

There Is No Fixed Maintenance Percentage

Singapore does not have one fixed percentage that determines child or spousal maintenance in every divorce.

The court considers the evidence and circumstances of the case.

Maintenance orders can involve:

• a fixed monthly payment;
• repayment of specific expenses;
• direct payment to a service provider; or
• another arrangement considered appropriate.

Official maintenance information is available from the Courts.

An online calculation cannot replace an agreement, legal advice or court order.

Income and Available Resources

Use realistic and supportable figures for both parents.

Monthly salary alone may not show the full financial position. Depending on the circumstances, relevant information can include:

• employment income;
• regular allowances;
• bonuses;
• business income;
• investment income;
• other financial resources;
• reasonable personal expenses; and
• existing financial obligations.

The calculator does not verify any entered amount or assess earning capacity.

The Singapore Tax Calculator can provide a separate personal income-tax estimate. Do not treat its result as the exact disposable income available for maintenance.

Assets and Maintenance Are Different

Maintenance is not calculated only from the value of personal assets.

However, assets and other financial resources may form part of a wider financial assessment.

If gold is included in a person’s financial records, the Gold Price Calculator Singapore can provide a basic metal-value estimate.

It does not prove ownership, determine matrimonial-asset division or decide how much maintenance should be paid.

Property division, ownership and maintenance are related legal issues but are not the same calculation.

Existing Payments Must Be Considered

The calculator shows a proportional comparison of total child expenses.

Before using the result in a discussion, identify expenses already paid directly by each parent.

For example, one parent may already pay school fees and insurance while the other covers food, transport and childcare.

Ignoring direct payments can create a misleading picture.

Prepare a simple list showing:

• each recurring expense;
• the monthly amount;
• who currently pays it;
• whether it is reasonable and necessary; and
• supporting documents available.

Civil and Muslim Family Matters

The correct process can depend on the law under which the marriage and divorce are handled.

Orders connected with Muslim divorces may involve the Syariah Court and can include matters such as maintenance, nafkah iddah or mutaah.

Faraid is a separate inheritance matter. The Faraid Calculator Singapore should not be used to calculate divorce maintenance.

Likewise, the Fidyah Calculator Singapore estimates a separate religious obligation and has no role in the maintenance-allocation formula.

More Singapore planning tools are available on the Calculator Singapores homepage.

When the Actual Order May Differ

A court order or negotiated agreement may differ from the calculator because it can consider:

• whether the expenses are reasonable;
• each parent’s income and earning capacity;
• other available resources;
• the children’s needs;
• care arrangements;
• direct payments already made;
• health and education requirements;
• existing liabilities;
• spousal needs;
• the matrimonial-asset outcome; and
• all other facts of the case.

The number shown by the calculator is only a starting point for preparing a budget.

Common Maintenance Calculation Mistakes

Avoid these common mistakes:

• treating the calculator as a court formula;
• entering one child’s expenses as the total for all children;
• including unreasonable or unsupported expenses;
• using gross income as available spending money without context;
• hiding income or financial resources;
• ignoring direct payments made by either parent;
• combining child and spousal maintenance without distinction;
• assuming equal care always means equal payment;
• confusing maintenance with matrimonial-asset division; or
• changing an existing court-ordered payment based only on this estimate.

Follow the existing order unless it is legally varied or replaced.

Frequently Asked Questions

Q1: What does the Singapore Divorce Maintenance Calculator calculate?

A: It provides a neutral proportional comparison of monthly child expenses using both parents’ entered resources. It also displays an entered spousal shortfall separately.

Q2: Does Singapore use a fixed percentage for child maintenance?

A: No. There is no universal percentage that decides every case.

Q3: Does the calculator predict a court order?

A: No. It cannot assess all the evidence and circumstances considered by a court.

Q4: Should I enter gross or net income?

A: Enter comparable and supportable monthly resource figures for both parents. Record how the figures were calculated and consider obtaining advice if the correct basis is disputed.

Q5: Does the higher-earning parent always pay all expenses?

A: Not necessarily. The actual arrangement depends on the children’s needs, both parents’ means, direct contributions and the circumstances of the case.

Q6: Does the spousal-shortfall field calculate legal entitlement?

A: No. It displays the amount entered for separate discussion and does not establish entitlement.

Q7: Can I use the result to reduce an existing maintenance order?

A: No. An existing order should be followed unless it is varied, suspended or cancelled through the proper process.

Q8: Does the calculator cover Syariah Court maintenance?

A: It is only a general budgeting tool. Muslim divorce matters can involve different orders and procedures, so obtain appropriate guidance.

Q9: Is the result legally binding?

A: No. It is an estimate for budgeting and discussion, not legal advice, an agreement or a court order.
