Affordability is usually tested against gross income, which is the least informative measure available. What decides whether a premium is affordable is what remains after the spending that cannot be moved.

This calculator works from income after tax, subtracts essential spending, and shows what share of the remainder every premium consumes - including the new one you are considering.

This is an estimate based on the values you entered. Actual premiums, coverage, eligibility and pricing vary by provider and by individual circumstances.

Insurance competes with everything else discretionary, which is why the share of discretionary income is a more honest measure than the share of gross income.

A premium that does not fit is a signal to re-examine coverage levels and deductibles before dropping cover entirely. Under-insuring to afford a premium usually costs more than it saves.

How to use the premium affordability calculator

  1. Enter monthly income after tax.
  2. Enter essential monthly spending: housing, food, transport, utilities, debt payments.
  3. Enter the total of premiums you already pay each month.
  4. Enter the new premium you are considering, then read what remains.

What people use this for

  • Deciding whether to add a policy before committing to it.
  • Checking whether total insurance spend has crept beyond what the budget supports.
  • Comparing two coverage levels on affordability rather than on price.
  • Setting a realistic premium ceiling before requesting quotes.

A premium that does not

The same household with $4,700 of essentials and a $340 new premium.

Discretionary income is the honest denominator

A premium taking 3% of gross income sounds trivial. The same premium can be 25% of what is left after housing, food, transport and debt payments - and that is the money it actually competes with.

Measuring against discretionary income also explains why two households on identical incomes reach opposite conclusions about the same policy. The difference is not the premium; it is everything above it.

What to do when it does not fit

The instinct is to drop cover. The better first step is to change the structure: a higher deductible, a shorter term, a lower limit that still matches the actual exposure, or a payment schedule with fewer fees.

Dropping cover entirely to afford a budget usually transfers a large uncertain cost onto a household that has just demonstrated it has no room for one. Reduce deliberately rather than abandon.

Methodology and assumptions

What this calculator does, and what it deliberately does not do.

  • Discretionary income is monthly income after tax minus essential spending, both as entered.
  • Shares are calculated against gross monthly income and against discretionary income separately.
  • No benchmark is applied. There is no universally correct share of income to spend on insurance.
  • All figures are estimates produced from the values you enter. This site has no rate feed and no carrier data, so it cannot quote or price a policy.
  • Nothing you type is transmitted or stored - the calculation runs entirely inside your browser.

This calculator provides an estimate based on the information you enter. Actual insurance premiums, coverage, eligibility and pricing vary by provider and individual circumstances.

This website is not an insurance company, an insurance agency or a licensed broker. It does not sell insurance, does not provide insurance quotes, and is not authorised to give advice about which policy you should buy.

No result produced here is an offer of insurance or a guarantee of coverage. Only a licensed insurer or agent, working from your verified details, can quote or bind a policy.

Frequently asked questions

What counts as essential spending?

Anything that cannot realistically be reduced within a month: housing, utilities, food, transport, childcare and contractual debt payments.

Should I include health insurance deducted from pay?

If it is deducted before you see the money, use income after that deduction and leave the premium out. Consistency matters more than which convention you pick.

Is there a maximum share I should spend?

No universal figure exists. It depends on what you own, who depends on you and how much loss you could absorb yourself.

What if the result is negative?

The premiums exceed what is available after essentials. That is a signal to restructure coverage rather than to stretch the budget.
