Which US services allow small/micro-payments using a credit card?
I don't know of any and it is unlikely that you will be able to find one.  Most credit card processors charge a flat fee plus percentage.  The flat fee is typically in the 35 cent range making the cost of doing business, in the manner you are suggesting, astronomical.   Also what you are suggesting is contrary to best practices as hosting services, and many other industries, offer deep discounts when making a single payment for an extended period of time. This is not very helpful, but I think it is unrealistic to find what you are suggesting.
You can split payments, and nobody judges you because most prepaid cards are actually gift cards.  They just think you have generous friends.   When you use Visa/MC at a vendor, they get dinged around 2-3% plus 35 cents flat-rate.  So when you ask them to charge 77 cents to the card, you're essentially asking they give half of it to Visa/MC.  Which is unfair.  A charity won't turn it down, but it's wasted.  So how do you solve this problem?  If you see a small merchant using Square or PayPal Here, their merchant agreements charge a flat rate (2.75% and 2.70% respectively) with no flat rate per transaction.  If you see they are on PayPal/Square, go for it.   Obviously PayPal itself doesn't have that problem, because they have a really, really good deal with Visa and Mastercard.  So feel free to buy yourself credit on your PayPal account with these residual values.   Amazon probably has a similar deal.   You are getting these small amounts because you aim to pay a $22.69 bill with a card that has $25 on it.  Reasonable, but it causes this.   Flip it around: pay a $22.69 bill with a card that has $20 on it, consume the $20 value, and pay the $2.69 in cash.  You may need to tell the cashier exactly the amount to charge (e.g. $20.00) especially if it is a Visa/MC card.  It will certainly go faster if you do.  The cashier may be able to pull up the balance, but it's an extra procedure, and an inexperienced cashier may struggle with it / have to call the manager etc. - not worth it in my book. I had $70K in credit card at one point.  Limited income, starting a business - it's the only credit available. (yes, all paid off now). There's an excellent new service called SelfScore that offers US credit cards to international students. They work with students without a credit history and even without an SSN by using other qualifying factors such as major, financial resources in their home country, and employability upon graduation. Worth clarifying: it's neither a secured credit card nor a prepaid card. It's a proper US credit card with no annual fees and a relatively low APR designed to help students build US credit. The spending limit is relatively small but that probably doesn't matter for just building a credit history. "It is called ""Credit card installments"" or ""Equal pay installments"", and I am not aware of them being widely used in the USA. While in other countries they are supported by banks directly (right?), in US you may find this option only in some big stores like home improvement stores, car dealerships, cell phone operators (so that you can buy a new phone) etc. Some stores allow 0% financing for, say, 12 months which is not exactly the same as installments but close, if you have discipline to pay $250 each month and not wait for 12 months to end. Splitting the big payment in parts means that the seller gets money in parts as well, and it adds risks of customer default, introduces debt collection possibility etc. That's why it's usually up to the merchants to support it - bank does not care in this case, from the bank point of view the store just charges the same card another $250 every month. In other countries banks support this option directly, I think, taking over or dividing the risk with the merchants. This has not happened in US. There is a company SplitIt which automates installments if stores want to support it but again, it means stores need to agree to it. Here is a simple article describing how credit cards work: https://www.usbank.com/credit-cards/how-credit-cards-work.html In general, if you move to US, you are unlikely to be able to get a regular credit card because you will not have any ""credit history"" which is a system designed to track each customer ability to get & pay off debt. The easiest way to build the history - request ""secured credit card"", which means you have to give the bank money up front and then they will give you a credit card with a credit limit equal to that amount. It's like a ""practice credit card"". You use it for 6-12 months and the bank will report your usage to credit bureaus, establishing your ""credit score"". After that you should be able to get your money back and convert your secured card into a regular credit card. Credit history can be also built by paying rent and utilities but that requires companies who collect money to report the payments to credit bureaus and very few do that. As anything else in US, there are some businesses which help to solve this problem for extra money." "I have a merchant account and accept Visa, Mastercard, and Discover but not AMEX. I don't take AMEX because they want me to go through another approval process (on top of what was required to get merchant status) and their fees are a percent or two higher than the other cards. This doesn't sound like a lot - but for a business that grosses $1M per year, an extra 2 percentage points is $20K. I don't gross $1M, but the additional cost for me to take AMEX would still use the word ""thousand"" and I don't see any reason to jump through extra hoops and fill out more forms for the privilege of giving extra money away. I haven't found anyone yet who wanted to pay me with AMEX who can't pay me with another card or a check instead." Dwolla looks to be a great option. But it requires users to have an account there (Free to sign up). And there rates are absolutely amazing.  Free for transactions under $10 $0.25 to receive money on transactions over $10 It may seem very simple on its face but you don't know the merchant's agreement.  You don't know who is providing the processing equipment.  You don't know a lot of things.  You know that Visa, Mastercard, Discover, Amex and others have network requirements and agreements.  You know that laws have been changed to allow merchant surcharges (previously it was contracts that prohibited surcharges, not laws).   That gas station, or that pizza parlor, or any other merchant doesn't have a direct relationship with Visa or Mastercard; it has an agreement with a bank or other processing entity.  The issue here, is whom do you even call?  And what would you gain?  Find out what bank is contracted for that particular equipment and file a complaint that the merchant charged you $0.35?  Maybe the merchant agreement allows surcharges up to state and local maximums?  You don't know the terms of their agreement.  Calling around to figure out what parties are involved to understand the terms of their agreement is a waste of time, like you said you can just go across the street if it's so offensive to you.  Or just carry a little cash.   If that's not the answer you're looking for, here's one for you: There is no practical recourse. I don't know of any that are comparable to credit cards. There's a reason for that. Debit cards, being newer, have a much lower interchange rate. Since collecting on debt is risky and less predictable, rewards / miles are paid from those interchange fees. This means with a debit card there's less money to pay you with. So what can you do? Assuming your credit isn't terrible, you can just open a credit card account and pay in full for purchases by the grace period. I don't know how all cards work, but my grace period allows me to pay in full by the billing date (roughly a month from purchase) and incur no finance charges. In effect, I get a small 30 day loan with no interest, and a cash back incentive (I dislike miles). You're also less liable for fraud via CC than debit. A lot of stores, especially smaller ones, won't accept card payments under $10.00. They pay a fee for taking cards and for small transactions it is not worth it. As long as you can be trusted with a Credit Card i find that if you have a setup that uses three accounts: 1. your Credit Card, 2. 2. a high interest internet account (most of these accounts don’t have fees), 3. a savings account.  The Method that works for me is: 1st i calculate my fixed monthly bills i.e Rent and utilities and then transfer it into my high interest account.  for the month whenever i make a purchase i transfer the money into the high interest account ( this way I can keep a running balance of what money I have left to spend in the month. Then when the Credit Card bill comes I transfer the money out of the high interest account across to pay off the Credit Card ( this way you generate interest on the money which you would have spent throughout the month and still maintain $0 of interest from the Credit Card) over a year you can generate at least enough money in interest to go out for dinner on one of free flights! Yes, but note that some credit card companies let you create virtual cards--you can define how much money is on them and how long they last.  If you're worried about a site you can use such a card to make the payment, then get rid of the virtual number so nobody can do dirty deeds with it. In practice, however, companies that do this are going to get stomped on hard by the credit card companies--other than outright scams it basically does not happen.  (Hacking is another matter--just pick up the newspaper.  It's not exactly unusual to read of hackers getting access to credit card information that they weren't supposed to have access to in the first place.) So long as you deal with a company that's been around for a while the risk is trivial. The short term loan that accept any credit score is really merchant cash advance. They call it loan because clients do have options to pay as direct deposit but most of the times they would make clients switch to their credit card terminals so they can get percentage of daily sales as payment as well as percentage from their partner credit card company. And that kind of payment (percentage of daily credit card sales) is merchant cash advance. There's never been a good micropayment system on the internet.  Credit card and paypal transaction costs are too high, and the whole thing takes too long.  The hassle of a credit card transaction only makes sense if you are making a major (5$ and up) purchase.  For micropayments there should be no lower limit on amounts, and contributing should take under a second.  Like a button that contributes 5 cents. "@Joe's original answer and the  example with proportionate application of the payment to the two balances is not quite what will happen with US credit cards. By US law (CARD Act of 2009), if you make only the minimum  required payment (or less), the credit-card company can choose which part of the balance that sum is applied to. I am not aware of any company that chooses to apply such payments to anything other than that part of the balance which carries the least interest rate  (including the 0% rate that ""results"" from acceptance of balance transfer  offers). If you make more than the minimum required payment, then the excess must, by law, be applied to paying off the highest rate balance. If the highest rate balance gets paid off completely, any remaining amount must be applied to second-highest rate balance, and so on.  Thus, it is not the case that that $600 payment (in Joe's example) is applied proportionately to the $5000 and $1000 balances owed. It depends on what the required minimum payment is. So, what would be the minimum required payment? The minimum payment is the total of (i) all finance charges incurred during that month, (ii) all service fees and penalties (e.g. fee for exceeding credit limit, fee for taking a cash advance, late payment penalty) and other charges (e.g. annual card fee) and (iii) a fraction of the outstanding balance that (by law) must be large enough to allow the customer to pay off the entire balance in a reasonable length of time. The law is silent on what is reasonable, but most companies use 1% (which would pay off the balance over 8.33 years).  Consider the numbers in Joe's example together with the following assumptions: $5000 and $1000 are the balances owed at the beginning of the month, no new charges or service fees during that month, and the previous month's minimum monthly payment was made on the day that the statement paid so that the finance charge for the current month is on the balances stated). The finance charge on the $5000 balance is $56.25, while the finance charge on the $1000 balance is $18.33, giving a minimum required payment of $56.25+18.33+60 = $134.58. Of the $600 payment, $134.58 would be applied to the lower-rate balance ($5000 + $56.25 = $5056.25) and reduce it to $4921.67. The excess $465.42 would be applied to the high-rate balance of $1000+18.33 = $1018.33 and reduce it to $552.91. In general, it is a bad idea to take a cash advance from a credit card. Don't do it unless you absolutely must have cash then and there to buy something from a merchant who does not accept credit cards, only cash, and don't be tempted to use the ""convenience checks"" that credit-card companies send you from time to time. All such cash advances not only carry larger rates of interest (there may also be upfront fees for taking an advance) but any purchases made during the rest of the month also become subject to finance charge. In other words, there is no ""grace period"" for new charges, and this state of affairs will last for one month beyond the first credit-card statement whose statement is paid off in full in timely fashion. Finally, turning to the question asked, viz. "" I am trying to determine how much I need to pay monthly to zero the balance, ...."", as per the above calculations, if the OP makes the minimum required payment of $134.58 plus $1018.33, that $134.58 will be applied to the low-rate balance and the rest $1018.33 will pay off the high-rate balance in full if the payment is made on the day the statement is issued. If payment is made later, but before the due date, that $1018.33 will be accruing finance charges until the date the payment is made, and these will appear as 22% rate balance on next month's statement. Similarly for the low-rate balance. What if several monthly payments will be required? The best calculator known to me is at https://powerpay.org (free but it is necessary to set up a username and password).  Enter in all the credit card balances and the different interest rates, and the total amount of  money that can be used to pay off the balances, and the site will lay out a payment plan.  (Basically, pay off the highest-interest rate balance as much as possible while making minimum required payments on the rest). Most people are surprised at how much can be saved (and how much shorter the time to be debt-free is) if one is willing to pay just a little bit more each month." There's no such service. The Israeli Credit Cards law is such that it will be very easy to defraud credit card issuers if such service was available. Check with the postal company if they allow doing it through their bank account, although their online service was horrible last time I checked. This is obviously country-dependent as laws differ from place to place.
