The achievable total is 20 + 2 \u00d7 40 = 100 kg \u2014 an exact match with the target.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to use the calculator<\/h2>\n<ol>\n<li>Enter your <strong>Target total weight<\/strong> \u2014 the bar plus all plates together \u2014 and pick kg or lb from the <strong>Unit<\/strong> selector.<\/li>\n<li>Enter the <strong>Bar weight<\/strong> (most Olympic bars weigh 20 kg \/ 45 lb; check the sleeve end if unsure) and choose its unit.<\/li>\n<li>List your plates in <strong>Plate pairs you have<\/strong>, one plate type per entry in the form \u201cweight x pairs\u201d. For example, <code>25 x 2<\/code> means you own two pairs of 25 kg plates (four plates in total). A plain entry like <code>15<\/code> counts as one pair. Separate entries with semicolons or new lines.<\/li>\n<li>Set the <strong>Plate weight unit<\/strong> so the calculator knows what the numbers in your list mean.<\/li>\n<li>Read the result: <strong>Plates on each side<\/strong> gives the loading, <strong>Achievable total weight<\/strong> shows what you can actually reach, and <strong>Difference from target<\/strong> tells you how close that is.<\/li>\n<\/ol>\n<p>All three units (target, bar, plates) can be different \u2014 the calculator converts between kg and lb automatically, which is handy when you train in a gym that mixes metric and imperial plates.<\/p>\n<h2>What the calculator does<\/h2>\n<p>When you program a lift, the number that matters is what ends up on the bar. But translating \u201c100 kg total\u201d into physical plates is not always simple: the bar itself contributes a fixed weight, plates come in fixed denominations, and you may not own every size. This calculator takes your equipment inventory and your goal, and returns the exact loading plan.<\/p>\n<p>The key insight is the per-side calculation. Because a barbell must be loaded symmetrically, every plate you add goes on in pairs. Once the bar weight is subtracted from the target, the remainder is split in two, and the calculator searches for the combination of your plate pairs that best matches that per-side amount.<\/p>\n<p>The search never exceeds the target: if your plates cannot hit the number exactly, you get the closest achievable weight below it. Among combinations that tie, it prefers fewer plates \u2014 so you spend less time loading and more time lifting. When a target cannot be reached exactly, small plates like 1.25 kg or 2.5 kg (or 2.5 lb and 5 lb) are what make fine adjustments possible, so it is worth listing them even if you rarely use them.<\/p>\n<h2>Tips, assumptions and limitations<\/h2>\n<ul>\n<li><strong>Always load both sides equally.<\/strong> The result assumes a symmetric load. Uneven loading changes the balance of the bar and can be unsafe, especially in the squat or bench press.<\/li>\n<li><strong>The result never exceeds the target.<\/strong> If an exact match is impossible with your plates, the calculator rounds down and shows the shortfall. Lifting slightly less than planned is almost always preferable to jumping above it mid-program.<\/li>\n<li><strong>Small denominations matter.<\/strong> Without plates of 2.5 kg or smaller, many targets are unreachable \u2014 with only 5 kg steps per side you can miss by up to 5 kg. Listing your smallest plates gives the calculator room to be precise.<\/li>\n<li><strong>Count pairs, not single plates.<\/strong> The entry \u201c25 x 2\u201d means two pairs (four plates). If you only have one 25 kg plate that cannot be paired, leave it out \u2014 an odd single plate has no use in a symmetric load.<\/li>\n<li><strong>Check plate accuracy.<\/strong> Cheap or old plates are often 1\u20133% off their stated weight, so the real bar load may differ slightly from the calculated one.<\/li>\n<li><strong>Collars are not counted.<\/strong> Spring or lock-jaw collars typically add 0.2\u20130.5 kg per pair; ignore this for training purposes, or add it to the bar weight if you want to be strict.<\/li>\n<\/ul>\n<p>If you are following a percentage-based program and want to know how strong you are relative to your body weight, the <a href=\"https:\/\/wpcalc.com\/en\/beauty\/power-to-weight-ratio-calculator\/\">Power-to-Weight Ratio calculator<\/a> is a useful companion tool.
