    Hello,
    is there a way to perform calculations in the output options? like [total] – [principle]?

      Hi Joseph,

      Not really possible. But it’s very easy to create new shortcodes that show the result you want. I can add [cost] which is total – principle. If you have paid for the pro version I can add this for free.

    hello
    how do i configure the calculator to use reducing balance method at an interest rate of 8%?
    for example, someone wants to borrow 2,000,000 so monthly instalments will be 776,067 but ensuring the calculator shows that, i have failed

      Hi Yebo,

      You need to upgrade and select amortisation in the interest settings

    Hello Support Team,
    I have following working out loan repayment but could not make it happen on calculator. Please I need help.

    Here is example of Repayment Table:
    Week; 5 6 7 8 9 10
    $500: 122.50 104.17 91.07 81.25 73.61 67.50

    Working out Formula:

    Principal x Interest / # of week in a year x No.# of week
    = Answer + $50 (Hidden Fee)= Interest
    = Interest + Principal
    = Answer (Balance Payable) / No.# of week Repayable

    Hi Graham,

    How do I go about displaying the repayment for weekly, fornightly and monthly repayment like the calculator on this page https://www.jacarandafinance.com.au/

    We will be using the paid version.

    Reply to Sandy

    • Graham on 08 Jul 2020:

      Hi Sandy,
      You can try these shortcodes: [weekly], [monthly] and [annual]. It’s been a long time since I added these so can’t remember exactly how they work.

    Hi Graham.

    I have the slider running on this page – https://turnerstraveller.co.za/payment-options/
    Under the LayUp (Pay Now, Travel Later) payment option.

    I’d like to have the slider under the Mobicred (Travel Now, Pay Later) payment option as well, but here it will use an interest rate to determine the monthly repayment amounts.

    Please, can you assist?

      Hi Hein,
      If you have the pro version you can put two calculators on the same page.

      Hi Nick,
      You can output anything you like. Set the ‘Repayment Divider’ value to 52 to get weeks from years.

      Reply to Graham

  9. shaun kelly on 24 Sep 2019:

    Can I set the term to years and repayment to weeks? I set the divider to 52 but it still shows as a yearly amount

    • Graham on 24 Sep 2019:

      Hi Shaun,
      Seems to be working now. On a $2000 loan over 2 years the weekly repayments are $34

    Annual rate: 36%
    monthly rate: 3.0%
    total interest: $ 12,000.00
    commission: 8%

    *I don’t know if numbers are ok, but this is the example of how a i want to see the results pf calculation

    The parameters of the calculator are:

    Minimum amount: $ 50,000
    Maximum Amount: $ 150,000
    Minimum term: 3 months
    Maximum period: 24 months

  13. tariq on 13 Apr 2019:

    Yes. That just calculates interest with (principle+service fee)

    i want the output to show the monthly repayment with service included. eg if the total payment including fees is 5000.
    The output should be 5000/term. im getting 5000 -fees/term

    Reply to tariq

    • Graham on 15 Apr 2019:

      Tariq,
      I’ve tested and the fees get added before interest is calculated. So not sure why it’s not working for you.

      Reply to Graham

  14. tariq on 13 Apr 2019:

    Hi

    How do you display monthly repayments = principal + interest + service fee /months.
    The repayments are calculating before the service fee is added ,displaying excluding the service fee.

    Reply to tariq

    • Graham on 13 Apr 2019:

      Hi Tariq,
      Have you tried using the option to add the fees before interest is calculated?

    Is it possible to do the following: Home sold for ($xxxxx) amount. You would save 3% = ($xxxxx) amount.

    Hi, I would like the Loan Period to be in “Years”, and display the repayment amount in “Months”.

    This is an expected requirement in most banks’ calculators. How do i do that ? It seems that if i select the Loan Period in “Years”, the repayment shown will be in “Years” too.

    If there’s no way around this, can i please request a refund on my purchase? thanks and much appreciated.

    Reply to James

    • Graham on 27 Nov 2018:

      Hi James,
      Set the repayment divider to 12 to get monthly repayments. Then use the [repayment] shortcode in the repayment terms.

      Reply to Graham

  20. tariq on 22 Nov 2018:

    hi. how do you get it to output on a new line in “output repayment terms”
    all the outputs go on a single line? should i use a comma or colon etc?

    Reply to tariq

    • Graham on 22 Nov 2018:

      I do this:
      Interest: [rate]<br>Repayment: [repayment] each [period]
      or this:
      p>Interest: <b>[rate]</b></p><p>Repayment: <b>[repayment]</b> each [period]</p>
      or you can use the [table] shortcode

    Hi there,

    I am trying to do an interest only loan so my [repayment] value seems to be incorrect…from what I can see it is including the actual repayment value too.

    Is there any way of outputting the monthly interest payment?

    Reply to Adam Johnson

    • Graham on 09 Oct 2018:

      Hi Adam,
      I could develop a shortcode for this but it would need a bit of thought as it will have to cope with loan periods of years, months and weeks. All you can do at the moment is output the total interest.

  22. Thanh on 25 Aug 2018:

    Hello, I want to substract an amount from the interest and display this result.
    Ex : interest 20 000€ and downpayment 2 000€, I want to display the result 18 000€.
    Please help me

    Reply to Thanh

    • Graham on 26 Aug 2018:

      Hi Thanh,
      I’m not sure you can do that. Downpayments are usually subtracted from the principle not the interest. In theory it could work but it may be that the downpayment is greater than the interest which would mean you owe them money.

    Hi Graham,
    Thank you for the reply. I put AUD as the currency code but you are right the error doesn’t stop it from working.
    Maybe custom shortcodes or is there a way to execute php (https://wordpress.org/plugins/allow-php-in-posts-and-pages/) to do something like [princple]*0.083 and or other calculations and display in the “Output Options”?

    Kind regards

    Thank you for your plugin. I have it at https://payx.com.au/ . I am having trouble with Warning: Invalid argument supplied for foreach() in /home/payxcom/public_html/wp-content/plugins/quick-interest-slider/settings.php on line 193 . Maybe it doesn’t like PHP 7.1?

    I am also have issues with calculating 90% and 8.3% of the slider value.

    Reply to Tim Lester

    • Graham on 31 Jul 2018:

      Hi Tim,
      Not sure why you are seeing the error message. That line is to do with the currency options and shouldn’t affect anything. As to the dual interest rates. You are trying to do something the plugin was never designed to do. I might be able to do something to use the primary and secondary interest rates but it’s not a simple fix.
