Generally speaking, the longer the term, the higher the rate but the greater the commitment.<\/p><p>You\u2019re committing to leaving your money in one place for the duration of the fixed-rate term. Technically you can withdraw your money, but will almost always incur a penalty, so it\u2019s not something to be entered into without careful consideration.<\/p><p>If you opt for a 3 year fixed-rate cash ISA then you might find rates that are better than at the shorter end of the spectrum, though that\u2019s not always the case.<\/p><h3>What is a 3-year fixed-rate cash ISA?<\/h3><p>Fixed-rate ISAs are a type of <u>cash<\/u> ISA. Unlike an instant access account with a variable rate, the rate is locked in for 3 years and you can\u2019t withdraw funds without incurring a penalty. This means that you\u2019re really committing to leaving your money alone to grow for 3 years.<\/p><p>You\u2019re allowed to pay up to a total of \u00a320,000 into ISAs each tax year.<\/p><p>Bear in mind that if you put a lump sum in a 3-year account now and rates end up rising in a year, your savings could miss out on the upturn. But the reverse is also true: if interest rates end up falling over the next year, you might be happy that you locked in when you did.<\/p><h3>Can I add more money during the 3-year term?<\/h3><p>Generally no. You will normally be given a window of time (usually several days or weeks) to deposit funds into the account, and after that time has passed, you can\u2019t add any more money. <\/p><p>From the banks\u2019 point of view, they don\u2019t know what rates will look like in the future. This means that fixed-rated accounts tend to offer an agreed amount based on what interest rates are today. <\/p><p>From the bank\u2019s perspective, if it had promised you a fixed rate and then was happy for you to add more funds while interest rates were falling, the bank would be paying over the odds on an increasing pot of money. A smart bank will always try to stay ahead of the game and limit the risk it\u2019s exposing itself to.<\/p><p>BUT, thanks to a rule change in April 2024, you can pay into more than one cash ISA in any tax year. So if you miss the window to add more money to a fixed-rate cash ISA, you could always open another one. <\/p><div class=\"importantText importantText__quote\">\n  <blockquote>\n    <div class=\"importantText__quoteIcon\"><\/div>\n    <p>Early withdrawal penalties can be harsh, so make sure you\u2019re comfortable leaving your savings alone until your fixed-rate account matures.\u201d<\/p>\n    <footer class=\"importantText__quoteAuthor\">\u2013 <cite>Katherine Denham, award-winning personal finance expert<\/cite><\/footer>\n  <\/blockquote>\n<\/div>\n<h3>An overview of our 3-year fixed-rate cash ISA comparison<\/h3>\n\n\n\n\n\n\n\n\n\n\n\n\n\n<table class=\"i_infobox product_infobox\">\n<tbody>\n<tr>\n<th>Rates up to<\/th>\n<td class=\"i_infobox_data product_infobox_data\">\n4.6% AER\n<\/td>\n<\/tr>\n<tr>\n<th>Number of accounts<\/th>\n<td class=\"i_infobox_data product_infobox_data\">\n55\n<\/td>\n<\/tr>\n<tr>\n<th>Minimum investment<\/th>\n<td class=\"i_infobox_data product_infobox_data\">\n\u00a31\n<\/td>\n<\/tr>\n<tr>\n<th>Maximum investment<\/th>\n<td class=\"i_infobox_data product_infobox_data\">\n\u00a35,000,000\n<\/td>\n<\/tr>\n<tr>\n<th>Opening options<\/th>\n<td class=\"i_infobox_data product_infobox_data\">\nBranch, website, mobile app, post, telephone<\/td>\n<\/tr>\n<\/tbody>\n<\/table><h3>Pros and cons of 3-year fixed ISAs<\/h3><div class=\"fin-pros-cons\">\n            <div class=\"fin-pros-cons__section\">\n            <h4 class=\"fin-pros-cons__heading\">Pros<\/h4>\n            <ul class=\"icon-list icon-list--check-circle\">\n                                    <li>You can usually get a better rate than on instant access or short-term accounts\u2026<\/li>\n                                    <li>\u2026and it's tax-free!<\/li>\n                                    <li>The rate is fixed until your account matures, so if market rates come down, yours won't.<\/li>\n                                    <li>If your circumstances change, then legally you are allowed to withdraw your funds (however you'd incur a penalty in doing so).<\/li>\n                            <\/ul>\n        <\/div>\n    \n            <div class=\"fin-pros-cons__section\">\n            <h4 class=\"fin-pros-cons__heading\">Cons<\/h4>\n            <ul class=\"icon-list icon-list--x-circle\">\n                                    <li>You'll need to leave the funds to grow for the full 3-year term (or incur a penalty).<\/li>\n                                    <li>If interest rates rise over the 3 years, the rate on your account won't.<\/li>\n                                    <li>You won't be able to add more funds during the 3-year term.<\/li>\n                            <\/ul>\n        <\/div>\n    <\/div>\n<h3>Frequently asked questions<\/h3><ul class=\"luna-accordionGroup accordionGroup\">\n\t<li class=\"luna-accordion\" data-accordion=\"accordion\">\n    <div class=\"luna-accordion__summary\">\n        <h4 class=\"luna-accordion__heading\">\n            <button class=\"luna-accordion__action collapsed\" aria-expanded=\"false\" aria-controls=\"faq-builder-0000000000\" data-toggle=\"collapse\" data-target=\"#faq-builder-0000000000\">\n                <span class=\"luna-accordion__title\">Can I transfer funds into a new 3-year ISA from my existing cash ISA?<\/span>\n                <svg class=\"luna-icon\" aria-hidden=\"true\">\n                    <use xlink:href=\"#chevron-down\" data-accordion-icon=\"show\"><\/use>\n                    <use xlink:href=\"#chevron-up\" data-accordion-icon=\"hide\" class=\"is-hidden\"><\/use>\n                <\/svg>\n            <\/button>\n        <\/h4>\n    <\/div>\n    <div class=\"luna-accordion__details collapse\" aria-hidden=\"true\" id=\"faq-builder-0000000000\" data-accordion=\"details\">\n        <div class=\"accordionContent\">\n            <div>\n                <p>Yes, in most cases this is possible, but you'll want to check the funding terms for the specific account that you have in mind.
