Kaiwhakatatau penapena

1. Kupu Whakataki

Kaiwhakatatau penapena he taputapu e āwhina ana i a koe ki te whakatau tata me pēhea te tipu o ō moni i roto i te wā, i runga i āu tāpui me te reiti huamoni. Ahakoa kei te whakamahere koe mō te reti, kei te hanga pūtea ohorere, kei te penapena rānei mō tētahi hoko nui, ka whakarato i tētahi matapae mārama mō tō toenga ā mua.

Mā te whakakotahi i tētahi tāpui tuatahi me ngā takoha ā-marama, ka whakaatu te kaitātai me pēhea te whakatere o te huamoni pūhui i te tipu o ō penapena. Ka wehewehea hoki e ia te nui o tō toenga katoa e ahu mai ana i āu ake takoha me te huamoni kua whiwhi.

He tino whaihua tēnei taputapu mō te hunga e hiahia ana ki te kite i te tipu pūtea mō te wā roa, ki te whakataurite i ngā rautaki penapena rerekē, ki te mārama rānei me pēhea te pānga o te auau whakakotahitanga ki ngā hua. Ka taea e ngā tīmata te whakamahi hei ako i ngā mātāpono o te huamoni pūhui, ā, ka taea e ngā kaiwhakamahi matatau te whakapai ake i ā rātou whakamahere pūtea.

2. Me pēhea te mahi

Ka whakatau tata te kaitātai i te uara ā mua o ō penapena mā te whakakotahi i ngā wāhanga e rua: he tāpui tuatahi kotahi me ngā takoha ā-marama ka hoki mai anō. Ka tipu ēnei wāhanga e rua i roto i te wā mā te whakamahi i te huamoni pūhui.

Ngā tawhā tāuru

• Moni: Te momo moni e whakamahia ana hei whakaatu i ngā hua.
• Tāpui Tuatahi: Te nui ka whakangao i te tīmatanga.
• Tāpui ā-Marama: Te nui ka tāpirihia ki ngā penapena ia marama.
• Reiti Huamoni ā-Tau (%): Te reiti hua ā-tau i mua i te whakakotahitanga.
• Wā Penapena: Te roanga katoa o te haumitanga.
• Auau Whakakotahitanga: E hia ngā wā ka whakakotahitia te huamoni ia tau (hei tauira, ā-tau, ia hauwhā, ia marama, ia rā).

Arorau tatau

Ka tipu te tāpui tuatahi mā te whakamahi i te tātai paerewa o te huamoni pūhui e hāngai ana ki te auau whakakotahitanga kua tīpakohia. Ka whakaarohia ngā takoha ā-marama hei annuity due, arā, ka mahia ngā tāpui i te tīmatanga o ia wāhanga, ā, ka piki ake ngā hua.

Hei whakarite kia ōrite ngā takoha ā-marama ki ngā auau whakakotahitanga rerekē, ka huri te pūnaha i te reiti ā-tau hei reiti ā-marama whaihua. Mā tēnei ka noho pūmau ngā tatauranga tipu ahakoa ngā wā whakakotahitanga.

Ngā ture whakamana

• Me whakakī ngā āpure katoa.
• Me noho te moni ki roto i te rārangi e tautokohia ana.
• Me tau ngā uara tāpui, ā, me noho ki roto i te awhe e whakaaetia ana.
• Me noho te reiti huamoni i waenga i te 0% me te 100%.
• Me noho ngā tau hei tauoti i waenga i te 1 me te 100.
• Me noho te auau whakakotahitanga hei uara kua whakaaetia (1, 2, 4, 12, 365).

Hanganga putanga

• Toenga Whakamutunga: Te uara katoa i muri i te wā haumitanga.
• Katoa o ngā Tāpui: Te tapeke o ngā takoha katoa.
• Katoa o te Huamoni: Ngā hua mai i te huamoni anake.
• Reiti ā-Tau Whaihua: Te hua tūturu ā-tau i muri i te whakakotahitanga.
• Hōtaka ā-Tau: Te wehenga o te toenga, ngā tāpui, me te huamoni mō ia tau.

Ngā here

E whakapae ana te kaitātai he pūmau te reiti huamoni me ngā takoha ā-marama. Kāore e whai whakaaro ki ngā tāke, te pikinga utu, rānei ngā reiti huamoni hurihuri, ā, ka taea ēnei te pā ki ngā hua tūturu.

3. Me pēhea te whakamahi i tēnei taputapu

1. Kōwhiria tō momo moni e pai ana.
2. Tāurua te nui o te tāpui tuatahi.
3. Tāurua te nui e whakamahere ana koe ki te penapena ia marama.
4. Whakaratohia te reiti huamoni ā-tau e tukuna ana e tō pēke, tō haumitanga rānei.
5. Tautuhia te maha o ngā tau ka penapena koe.
6. Kōwhiria te auau whakakotahitanga o te huamoni.
7. Pāwhiritia te tatau kia kite i ngā hua.
8. Arotakehia te whakarāpopototanga me te wehenga ā-tau kia mārama ai koe ki te tipu o ō penapena.

4. Ngā tauira mahi

Tauira 1: Penapena wā roa

Tāuru:

• Tāpui Tuatahi: $10,000
• Tāpui ā-Marama: $500
• Reiti ā-Tau: 5%
• Ngā Tau: 20
• Auau Whakakotahitanga: Ia marama

Putanga:

• Toenga Whakamutunga: ~$216,300
• Katoa o ngā Tāpui: $124,000
• Katoa o te Huamoni: ~$92,300

E whakaatu ana tēnei āhuatanga me pēhea te kaha o ngā takoha ā-marama pūmau ki te whakapiki i ngā penapena mō te wā roa.

Tauira 2: Kāore he huamoni

Tāuru:

  annual_rate: 5,
  years: 20,
  compound_frequency: 12
});
console.log(result.final_balance);

Tauira (PHP)

$data = [
  'initial_deposit' => 10000,
  'monthly_deposit' => 500,
  'annual_rate' => 5,
  'years' => 20,
  'compound_frequency' => 12
];
$result = savings_calculator($data);
echo $result['final_balance'];

Me whakamana e ngā kaiwhakawhanake ngā tāuru tau katoa, me whakatinana awhe pūmau, me horoi hoki ngā waehere moni hei ārai i ngā raraunga hē, i ngā mōrea whakaurunga rānei. Me whakatakoto ngā putanga kia ōrite mō te whakaatu me ngā whakautu API.

Kei roto i tēnei taputapu ngā tāke me te pikinga utu?

Kāo, e whakapae ana he pūmau te reiti huamoni, ā, kāore e whai whakaaro ki ngā tāke, ki te pikinga utu rānei.

Ka taea e au te whakamahi uara tōraro?

Kāo, me noho ngā tāuru katoa hei kore, hei uara pai rānei i roto i te awhe e whakaaetia ana.

He aha te take nui o te auau whakakotahitanga?

Ko te whakakotahitanga auau ake ka hua ake he hua nui ake nā te mea ka tatauria te huamoni i ngā wā maha ake.

He tika tēnei kaitātai mō ngā haumitanga tūturu?

Ka tuku i tētahi whakatau tata pono, engari ka rerekē pea ngā hua tūturu i runga i ngā āhuatanga o te mākete me ngā utu.
