Jquery: calculations with real money mask and date sum

Question

I have a screen ready. But there are some adjustments that I’m having trouble solving.

One of them is the calculation of values with the mask of Real. Without it, it works perfectly. With it the result is Nan (the "Value" field receives the same and calculates for "Provision franchising royalties", "Provision advertising fund" and "Provision franchising royalties"). The date is adding up, but with crazy results (the "Issue date" calculates for "1st maturity", "2nd maturity" and "3rd maturity").

I’ve been working on it all day and I tried to add the script links, but I couldn’t.

This is the mask for Real (* maskMoney plugin for jQuery * http://plentz.github.com/jquery-maskmoney/) and this is the date mask (jQuery Mask Plugin v1.14.10 // github.com/igorescobar/jQuery-Mask-Plugin).

Follow what I’ve managed to do so far.

$(document).ready(function() {
  /****** Função percentual ******/
  function funcao_percentual(valor_1, destino, percentual) {
    $(valor_1).on("click", function() {
      $(destino).val('');
    });

    function arredondar(valor, casas) {
      var novo = Math.round(valor * Math.pow(10, casas)) / Math.pow(10, casas);
      return (novo);
    }

    $(valor_1).blur(function() {
      valor = $(this).val();
      porcentagem = percentual; // PORCENTAGEM A SER ADICIONADA
      total = (parseFloat((valor * porcentagem) / 100));
      $(destino).val(arredondar(total, 2));
    });
  }

  /****** Função subtrair ******/
  function funcao_subtrair(valor_1, valor_2, inicio, destino) {
    $(inicio).on("click", function() {
      $(destino).val('');
    });

    function arredondar(valor, casas) {
      var novo = Math.round(valor * Math.pow(10, casas)) / Math.pow(10, casas);
      return (novo);
    }

    $(inicio).blur(function() {
      valor_1_v = $(valor_1).val();
      valor_2_v = $(valor_2).val();
      total = (parseFloat((valor_1_v - valor_2_v)));
      $(destino).val(arredondar(total, 2));
    });
  }

  /****** Função calcular a data ******/
  function funcao_calcular_data(data_inicial, data_final, dias) {
    $(data_inicial).blur(function() {
      $(data_inicial).on("click", function() {
        $(data_final).val('');
      });

      var data_ini = $(data_inicial).val();

      var date = new Date(data_ini);
      date.setDate(date.getDate() + dias);
      var futDate = date.getDate() + "/" + date.getMonth() + "/" + date.getFullYear();


      $(data_final).val(futDate);
    });
  }

  /****** Percentual de Provisão - Royalties (franchising) ******/
  funcao_percentual("#valor", "#provisao_royalties_franchising", 39.85)

  /****** Percentual de Provisão Fundo Propaganda ******/
  funcao_percentual("#valor", "#provisao_fundo_propaganda", 3)

  /****** Subtração de Provisão - Royalties ( franchising) ******/
  funcao_subtrair("#provisao_royalties_franchising", "#provisao_fundo_propaganda", "#valor", "#provisao_royalties_franchising_2")

  /****** 1º vencimento ******/
  funcao_calcular_data("#data_emissao", "#1_venc", 28)

  /****** 2º vencimento ******/
  funcao_calcular_data("#data_emissao", "#2_venc", 42)

  /****** 3º vencimento ******/
  funcao_calcular_data("#data_emissao", "#3_venc", 56)


});

$(document).ready(function() {
  $('#data_emissao').mask('00/00/0000');
  $('#vencimento').mask('00/00/0000');
  $('#1_venc').mask('00/00/0000');
  $('#2_venc').mask('00/00/0000');
  $('#3_venc').mask('00/00/0000');
  $('#data_emissao_2').mask('00/00/0000');
  $('#vencimento_2').mask('00/00/0000');
  $('#data_emissao_3').mask('00/00/0000');
  $('#vencimento_3').mask('00/00/0000');
});

$(function() {
  $(".valor").maskMoney({
    symbol: 'R$ ',
    showSymbol: true,
    thousands: '.',
    decimal: ',',
    symbolStay: true
  });
})
