Emergency savings before extra mortgage repayments

Home equity is not emergency cash

A lower mortgage balance is valuable, but accessing that equity later may require lender approval, a new facility or sale. Revolving credit and redraw-like access have product conditions and should not replace a deliberate cash reserve.

Sorted recommends accessible emergency savings and notes that even a small starter amount can help. The reserve size should reflect income variability, dependants, insurance excesses and likely home costs.

Example: offset the reserve, repay the surplus

A household identifies three categories: urgent reserve, known annual expenses and long-term surplus. The first two stay accessible. If an offset product is cost-effective, the reserve may reduce interest while remaining separate from principal.

Only the long-term surplus is considered for direct repayment. A planned withdrawal is modelled by lowering the offset balance rather than pretending the highest balance remains all year.

Build a resilient cash floor

1. List required mortgage and essential living costs.
2. Include annual bills, repairs and insurance excesses.
3. Choose a period suited to income stability.
4. Keep the money safe and reasonably accessible.
5. Separate planned spending from emergencies.
6. Rebuild the reserve before restarting extra repayments.

Pause conditions

Stop voluntary extras after a reserve withdrawal, income shock or significant rate increase. If a required payment may be missed, contact the lender early rather than sending money to preserve an old payoff target.

• Do not count unused revolving credit as savings.
• Avoid expensive debt to maintain extra payments.
• Check offset fees and account eligibility.
• Agree the reserve with joint borrowers.
• Seek budgeting or hardship help before arrears grow.

Use a calculator as a scenario, not a promise

Use a zero-extra scenario beside the proposed plan and enter stable offset cash separately. The calculator cannot value liquidity or choose an emergency target.

The New Zealand model accrues interest across actual calendar days, using 365 days or 366 in a leap year. It supports monthly, fortnightly and weekly schedules and treats a stable offset balance separately from principal.

The estimate holds the entered rate constant, assumes extras reach principal and excludes revolving-credit cash flow. Fixed-loan limits, refix rates, break fees, posting and lender rounding can change the actual result.

Review the plan before money leaves

Compare a zero-extra case, the intended plan and an interrupted plan with identical starting inputs. For floating or split debt, rerun at other rates without presenting them as predictions. Stop the projection at a refix date when the next rate is not known.

Keep the loan agreement, latest statement and written lender answers about fixed-loan limits, break fees and payment allocation. Model each split separately when its rate, fixed expiry, offset treatment or flexibility differs.

• Secure required repayments and essential costs first.
• Keep emergency and planned-expense cash accessible.
• Name the intended loan split for an extra payment.
• Verify the transaction and principal on the next statement.
• Rerun after a refix, rate change, fee or product restructure.
