A rent advertised by the week can be difficult to compare with a monthly budget. This calculator puts weekly and fortnightly rent on the same 52-week basis. Enter the rent for one complete payment period, choose weekly or fortnightly, and optionally add a start or end date for a part-month amount.
Multiplying weekly rent by four gives a four-week amount, covering 28 days. It does not give the monthly equivalent used here. A 52-week year contains thirteen four-week periods but twelve calendar months. Dividing the annual rent by twelve spreads those thirteen periods across twelve equal budgeting amounts. The result is a comparison convention, not a statement that a particular rent payment must follow it.
A fortnight contains two weeks, so there are 26 fortnights in this convention, and the calculator uses the fortnightly amount directly.
At $650 per week, yearly rent is $650 × 52 = $33,800. Dividing by twelve gives $2,816.67 a month, while a fortnight is $1,300. Entering $1,300 and selecting fortnightly produces the same three answers.
For a start date of 27 October 2026, the assumed partial month runs from 27 to 31 October. Both dates count, giving five days. The weekly daily-rate method calculates $650 ÷ 7 × 5 = $464.29. With the calendar-month method, the unrounded $2,816.666666 monthly equivalent is divided by 31 and multiplied by five, giving $454.30. The method explains the difference.
For comparison, $400 weekly converts to $1,733.33 monthly and $20,800 yearly; $500 converts to $2,166.67 and $26,000; $600 converts to $2,600 and $31,200.
Leaving the date blank still gives all three period conversions; only the prorated result needs a date. Selecting a start date counts from that date to the last day of its calendar month. Selecting an end date counts from the first day of its month through the chosen date. There is no assumed move-in date or invented lease period hidden in the result.
The weekly daily-rate method divides weekly rent by seven, or fortnightly rent by fourteen, before multiplying by the occupied days. The calendar-month method divides the unrounded monthly equivalent by the actual number of days in that month. February can have 28 or 29 days. A one-day interval counts once.
Only one calendar month is considered. A rental period beginning mid-month, an interval spanning multiple months, a rent change during the period, or a refund after an early departure requires the relevant agreement and dates. The form does not establish a legal entitlement to a refund or a right to end a tenancy. It also does not subtract rent already paid, arrears, concessions or separate utility charges.
The annual conversion always uses 52 weeks, equal to 364 days. It does not add a day for ordinary calendar years or two for leap years.
Consumer Affairs Victoria publishes a different calendar-month conversion: daily rent × 365 ÷ 12, using a 365-day year even in leap years. Starting with weekly rent, its daily amount is weekly rent divided by seven. At $650 weekly, that method gives $2,824.40 monthly. This calculator keeps its specified 52-week monthly comparison, so the two monthly results should not be mistaken for the same convention.
Victorian guidance also explains that the rental agreement identifies the payment period. Follow the agreement and the tenancy authority for your state or territory when deciding the amount payable. A general budgeting conversion does not override those requirements.
Ask your state or territory tenancy authority, or a solicitor, if the agreement and payment request use different methods, the parties disagree about the move-out day, prepaid rent is disputed, or a proposed deposit deduction includes unpaid rent. Keep the agreement, payment receipts and date records together.
For the 52-week budgeting convention used here, multiply weekly rent by 52 and divide by 12. At $650 a week that is $2,816.67 a month. Four weeks is only 28 days, so multiplying by four understates this monthly equivalent. Check the method in your agreement and local guidance before using it for payment.
Multiply fortnightly rent by 26 and divide by 12. For example, $1,300 a fortnight gives $33,800 a year and $2,816.67 a month. The calculation retains precision until the final cent; it does not round a derived weekly amount first.
Consumer Affairs Victoria’s calculator converts a daily rent to calendar monthly rent using daily rent × 365 ÷ 12, including in leap years. With a weekly input, daily rent is weekly rent ÷ 7. This differs from the 52-week monthly budgeting figure shown here. Follow the linked Victorian calculator and your rental agreement for the applicable payment amount.
Using the weekly daily-rate method, divide weekly rent by seven and multiply by five. At $650 weekly, five days cost $464.29. Select a start or end date that leaves five days within its calendar month. Both boundary dates count. The calendar-month method instead divides the unrounded monthly equivalent by that month’s actual days.
