How do I convert weekly pay to monthly?

Multiply weekly pay by 52 to get the annual figure, then divide by 12 for monthly. There are not exactly four weeks in a month, so multiplying weekly by four understates monthly pay. This calculator does the conversion correctly.

Does this show take-home pay?

Yes. It applies PAYE income tax, the ACC earners levy, and optional KiwiSaver and student loan deductions to show your net pay at each frequency, not just the gross.

Why compare pay at different frequencies?

Job offers are quoted on different cycles, and bills fall on their own schedule. Seeing your pay at every frequency helps you compare offers fairly and line up your budget with your actual pay rhythm.

Pay Frequency Converter

This calculator converts your pay between weekly, fortnightly, four-weekly, monthly and annual amounts, on both a gross and an after-tax basis, so you know what a quoted salary or wage really means for your budget. New Zealand employers pay on different cycles, and it is easy to get caught out comparing a weekly wage with a monthly salary, especially since a month is not simply four weeks. You enter your pay amount, choose how often you are paid (weekly, fortnightly, four-weekly, monthly or annually), then select your KiwiSaver rate and whether you have a student loan. The calculator converts your figure to an annual amount, applies the current PAYE tax brackets, the ACC earners' levy up to its cap, your KiwiSaver contribution and any student loan repayment, then divides the gross and net annual totals back into every frequency. The results table shows gross and take-home (net) pay side by side for each frequency, so you can line up bills and automatic payments with your real pay rhythm, or compare job offers quoted on different cycles without doing the maths yourself. It is an estimate based on standard PAYE brackets, the current ACC levy and threshold, and the standard 12% student loan rate; your actual take-home may differ depending on your tax code and other deductions, so treat the figures as general information rather than financial advice.

Based on the current PAYE brackets and an ACC earners levy of 1.75% up to the annual maximum ($156,641). Student loan is estimated at the standard 12% above the repayment threshold. KiwiSaver is your employee contribution. Estimate only, tax settings change so check current figures. General information, not financial advice.

How it works

The calculator first converts your entered pay to an annual figure by multiplying by the number of pay periods in a year. It then applies the PAYE income tax brackets, the ACC earners levy up to the annual cap, your student loan repayment if it applies, and your KiwiSaver employee contribution, to find your annual take-home. Finally it divides both the gross and net annual figures back into each frequency, so you can see exactly what lands in your account weekly, fortnightly, four-weekly and monthly.

Worked example

An annual salary of $78,000 is $1,500 a week gross. After PAYE, the ACC levy and a 3% KiwiSaver contribution, the weekly take-home is lower, and the monthly figure is the annual net divided by 12, which is more than four times the weekly because a month is longer than four weeks.
