    Hola, me podrían indicar como puedo hacer para omitir un rango de mes, requiero colocar solo 3, 6 y 12 meses, pero al colocar el salto de meses de 3, me sale el 9 necesito omitirlo. muchas gracias.

      Si ha actualizado, puede usar la opción ‘botones de término’. De esa forma podrás tener botones durante 3, 6 y 12 meses (google translation).

    Can you create something like these:



    Thanks in advance. =)

      Hi Chloe,
      Yes I can. The calculator part isn’t complicated. But if you want all those graphics and animations it can get very expensive.

    Do you have dropdown option instead of sliders in Pro?

    Reply to Marjorie

    • Graham on 13 Jul 2020:

      Hi Marjorie,
      No I don’t. Nobody has ever asked for this before. It’s possible to do but not a 5 minute fix. I can send you a quote for the work if you want. Probably around 2 hours to do everything.

    Hi Graham,

    I’ve bought the Pro Version but I can’t get the APR to work properly. Any chance you could send over the settings for the “Motorhome Finance calculator” as that’s exactly how mine should be looking?


    Reply to Jonatas

    • Graham on 18 Mar 2020:

      The motorhome finance project is a bespoke version. Their calculation is unique to their version. What are you trying to do with the APR?

      Reply to Graham

      • Jonatas on 26 Mar 2020:

        Hi Graham,

        Ah, sorry if it seemed like I’m trying to steal the bespoke version. I just need the correct settings to get APR to work properly, it can be a simple sample or something similar if it helps.

        I’m trying to set-up something that has “How much would you like to borrow”, and “Over how long?”, with different APRs based on period.

        Here’s what I’ve got until now: https://www.wizborn.co.uk/calculator/

        Thank you,

          Install this: https://loanpaymentplugin.com/qis-update/

          Then in the settings click on the ‘Show all settings’ option. You will now see 7 interest triggers you can set to change the rates at set periods.

            Hi Graham,

            Thanks for the reply.

            I’ve installed but I think I was already using this version.

            Also, I already had 5 out of those 7 triggers in use.

            Is there anything else you can do to point me in the right direction?


          • Graham on 28 Mar 2020:

            I’m obviously a bit confused as to what you want to do. The triggers is the way to change the APR based on the period. Unless you want to offer different repayment periods (eg: weekly, monthly, quarterly). If this is the case it’s a bit more complicated. You could use the Advanced Interest Options and set the rates that way.

    Hi Graham, nice and straight forward plugin. It fulfills most of my needs. Does the calculated results show up on the contact form after clicked the bottom? And you mentioned that you would create a custom contact form when you get paid. How can i show you my desired layout for the contact form so you could tell me the price? THX

    Reply to David

    • Graham on 06 Mar 2020:

      At the moment all you get when you submit the form is the amount and term. I should be able to fix it so you can email the repayment amount as well. Send your layout to mail at quick-plugins.com

    I’m wondering if you can help. I’m currently designing a collection of new websites and we want to integrate an APR calculator that we can use across 5-6 websites.

    The calculator we’re looking to use will have the following functions;

    (These answers would effect the rate thrown out)
    Drop Down: Type of Asset
    Radial Button: I consider my credit to be: Excellent, Average, Poor
    I am a: Home Owner, Tenant

    Amount of loan
    Period of loan (months)
    Representative APR:
    Payment amount: Answer

    Is this something you could possibly help us with?

    • Graham on 18 Dec 2019:

      Hi Ryan,
      I’ve got most of those options in various guises in one plugin or another. For example, the credit rating here: https://bankcomparisonplugin.com/
      I’ll send you an email with some idea of costs.

      Hi Eduardo,
      The pro version costs $35 – you can get this bu clicking on the ‘Upgrade’ tab.

      The interest rate selector only has 4 options right now but I can add more if you want.

    Hi, Graham,
    I will prefer a discussion through email. I have need a complete loan plugin that can carry out these feature. Do you have any or can you help out?
    Users should be able to ask for small money and pay some interest. They should have their own profile with their pictures, They should be able to register, login and out, make loan request, see approval status, see repayment status, upload necessary documents and fill forms as part of registration, and also reply for more loan after completion of existing loan. They should also be able to access history of all their loan request and payments.
    Admin should be able to see and review customers loan request and documents, and make correction; also approve, put in waiting, decline, and blacklist borrower. Also download, filter and update database, add new loan products.
    Website should be able to have online chat, and auto emails between borrower and admin (notifications.)

    how do i purchase the CaraCU form?
    can it be configured?
    Also, i want to do various ones, such as one for loan, one for mortgage.
    But give them the option to select bad credit, good, excellent and it will show different rates based on the selection

    Hi there, I have a client who is looking for a simple “interest saved = $xxx ” type of calc. I’m unclear from your calcs on your site if any of them will do that. What I’m hoping to create is a landing page where a user can input what they are paying now, the term left on the loan, and what their interest rate is now. My client wants to be able to input the best rate he can get them (he’s a broker) and then have the calc tell them based on his rate, how much they could be saving. Is that possible with one of your calcs?

    • Graham on 14 Nov 2018:

      Hi Neil,
      It’s not an option at the moment but I did build something similar for a real estate client some time back that did the same. Does your client want sliders or will users type in the numbers?
