Mae sawl ffordd y gallet ti gynilo (safio) arian, ac un o’r opsiynau i’w ystyried yw agor cyfrif cynilo.<\/h2>\n\n\n\n

Beth yw cyfrif cynilo?<\/h3>\n\n\n\n

Mae cyfrif cynilo yn le diogel i ti gadw arian at y dyfodol. Yn wahanol i gyfrif banc arferol sy’n cael ei ddefnyddio ar gyfer gwario bob dydd, mae cyfrif cynilo yn talu llog (interest) fel arfer.<\/p>\n\n\n\n

Llog yw arian sy’n cael ei ychwanegu gan y banc am gadw’r arian gyda nhw. Yr uchaf yw’r gyfradd llog (interest rate), y mwy o arian bydd yn cael ei ychwanegu. Mae’n ffordd wych i wylio dy arian yn tyfu dros gyfnod.<\/p>\n\n\n\n

Cyfrif cynilo mynediad hawdd<\/h3>\n\n\n\n

Mae cyfrif mynediad hawdd yn un o’r ffyrdd mwyaf syml i gynilo. Rwyt ti’n gallu rhoi arian i mewn a thynnu arian allan unrhyw amser. Os wyt ti angen arian yn sydyn ar gyfer anrheg pen-blwydd neu wyliau, mae posib cael at hwn yn syth. Mae’r gyfradd llog yn eithaf isel fel arfer am ei fod mor hawdd tynnu arian allan. Mae’n anoddach i ti gynilo hefyd os yw’r temtasiwn yno i dynnu’r arian allan.<\/p>\n\n\n\n

Cyfrifon cynilo rheolaidd<\/h3>\n\n\n\n

Mae cyfrif cynilo rheolaidd ychydig yn wahanol. Mae angen i ti addo rhoi swm penodol o arian i mewn bob mis, fel \u00a310 neu \u00a320. Yn aml y rhain sy’n cynnig y cyfraddau llog uchaf sydd ar gael. Mae hyn yn dda os oes gen ti swydd rhan amser neu arian poced reolaidd ac yn awyddus i ddechrau cynilo. Ond, gyda’r cyfrifon yma, mae cyfyngiad ar faint rwyt ti’n cael rhoi i mewn mis, a bydd y banc yn gostwng y gyfradd llog os wyt ti’n colli mis neu’n tynnu arian allan.<\/p>\n\n\n\n

Cyfrifon cynilo tymor penodol<\/h3>\n\n\n\n

Os wyt ti’n chwilio am gyfradd llog sicr, efallai bydd cyfrif tymor penodol yn dda i ti. Rwyt ti’n cael cyfradd llog uwch wedi’i warantu am gyfnod penodol, fel blwyddyn neu ddwy. Mae hyn yn golygu y byddi di’ n gwybod yn union faint o arian byddi di wedi elwa erbyn y diwedd. Ond y broblem yw na fedri di gael mynediad i’r arian yma nes bydd y cyfnod wedi dod i ben. Os wyt ti angen yr arian mewn argyfwng, yna ni fedri di gael yr arian yma allan, neu rwyt ti’n gorfod talu ffi fawr i wneud hyn.<\/p>\n\n\n\n

Beth yw ISA?<\/h3>\n\n\n\n

Cyfrif Cynilo Unigol yw ISA. Os wyt ti’n derbyn llawer o arian llog yna gall y llywodraeth gymryd swm o hwn gen ti mewn treth. Gyda ISA, mae’r holl log rwyt ti’n derbyn yn hollol ddi-dreth.<\/p>\n\n\n\n

Mae posib agor ISA Iau pan fydd rhywun yn cael ei eni (gyda help rhiant), a ISA arian parod safonol ar \u00f4l i ti droi’n 18 oed. Gyda ISA Iau nid wyt ti’n cael tynnu’r arian allan nes i ti droi’n 18. Unwaith i ti droi’n 18 oed, mae’r arian yma yn dod yn arian i ti.<\/p>\n\n\n\n

MoApiau a photiau cynilo arian<\/h3>\n\n\n\n

Os wyt ti dros 16 oed, mae posib agor cyfrifon gyda banciau digidol fel Monzo neu Starling. Mae gan sawl banc traddodiadol y stryd fawr apiau da hefyd.<\/p>\n\n\n\n

Mae gan lawer o’r apiau yma nodwedd gelwir yn “potiau”. Mae hyn yn caniat\u00e1u i ti rannu dy brif cynilon i mewn i gadw-mi-gei digidol llai. Gallet ti alw un pot yn ‘Gwyliau Haf’ ac un arall yn ‘Esgidiau Newydd’. Gallet ti osod yr ap i gasglu unrhyw geiniogau dros ben pan fyddi di’n prynu rhywbeth a’i roi yn syth i mewn i bot arall. Mae’n gwneud i gynilo teimlo’n awtomatig, ac rwyt ti’n cynilo heb sylweddoli!<\/p>\n\n\n\n

Chwilia o gwmpas am y fargen orau<\/h3>\n\n\n\n

Mae pob banc yn cynnig cyfraddau llog a manteision gwahanol. Efallai y bydd rhai yn rhoi taleb neu rywbeth am ddim i ti pan fyddi di’n cofrestru, neu efallai eu bod yn cynnig cyfradd llog llawer gwell. Rho amser i ymchwilio a chymharu ar-lein. Paid aros gyda’r un banc am fod dy deulu neu ffrindiau yn ei ddefnyddio, edrycha ar rai eraill gyntaf cyn gwneud penderfyniad.<\/p>\n\n\n\n

Cynilo os nad wyt ti’n ddigon hen<\/h3>\n\n\n\n

Os wyt ti’n rhy ifanc i agor cyfrif ar ben dy hun, neu os nad oes gen ti’r ID sydd ei angen eto, paid poeni. Gallet ti ofyn i riant, gofalwr, neu oedolyn gallet ti ymddiried ynddynt, i agor cyfrif cynilo plentyn i ti. Nhw fydd \u00e2 rheolaeth o’r cyfrif, ond dy arian di ydyw.<\/p>\n\n\n\n

Gallet ti hefyd gynilo gydag arian parod. Mae cael cadw-mi-gei neu jar yn dy ystafell wely yn ffordd dda i gychwyn. Mae gweld y ceiniogau a’r arian papur yn pentyrru mewn jar yn deimlad boddhaol iawn. Mae pob ceiniog rwyt ti’n arbed nawr yn helpu ti yn hwyrach ymlaen.<\/p>\n\n\n\n
