Calculation rules
Payments are monthly, using monthly compounding and the annual interest rate divided by 12. The regular payment and each month's interest are rounded to the nearest cent, with ties rounded away from zero; the final payment clears the remaining balance and interest.
Taxes, insurance, PMI and fees are not included.
Example values illustrate the calculation and are not a loan offer.
Frequently asked questions
- How is the monthly payment calculated?
- The payment uses the loan amount, monthly interest rate and number of monthly payments. A $250,000 loan at 6.5% over 30 years has a regular monthly payment of $1,580.17.
- What does the loan calculator amortization table show?
- Each monthly row shows the payment, interest, principal repaid and remaining balance. Switch to Yearly for a summary, download the schedule as CSV or copy the table.
- Can I use this as a car amortization calculator?
- Yes, for a loan with the monthly-payment assumptions shown here. Enter the amount borrowed, annual rate, term and first payment month; fees are not included.
- Why can the final payment differ?
- The regular payment and monthly interest are rounded to cents. The last payment pays off the remaining balance and interest, so multiplying the regular payment by the number of months may not match the total paid.
- What happens at 0% interest?
- Each payment repays principal without interest. The regular payment is the loan amount divided by the number of payments, rounded to cents, and the last payment clears any rounding difference.
Privacy on this page
Calculations run in your browser. The loan amounts, rates and terms you enter are not sent to the server or saved in browser storage. Reloading the page returns the inputs to their initial state.
To understand how the page is used and to improve the service, this page sends semku’s own usage statistics and automatic error reports. They go only to the dedicated endpoint under semku.com/api/telemetry/v1/. They are not used for advertising or third-party tracking.
The usage statistics include the stage of use (such as starting an operation or requesting a copy), the time it happened and fixed identifiers that distinguish the page and feature. They do not include the loan amounts, rates or terms you enter, the results shown or the text you copy. Inputs are not sent as hashes or as size categories either. The full URL and search terms are not sent.
Operations and sessions are distinguished by randomly generated identifiers. In the browser these exist only in temporary memory and are not written to cookies or browser storage. No identification based on cookies or combined device characteristics is used.
Error reports contain the error type, code and time, and, where available, a registered program-source identifier with the line and column number. The error message text and stack traces are not sent. Usage statistics and error reports also carry the site identifier, the published build and a random record identifier. For access records such as IP addresses, browser signals (User-Agent Client Hints), region and language, see the paragraph below.
The feedback form sends the rating you chose and the text you typed in the free-text field when you press the send button. A random ID that distinguishes the submission, the page, site and published build, and the type of request are also sent. There are no fields for your name, email address or phone number, and the values you enter are not attached automatically. Whatever you write in the free-text field is sent as is. Please do not enter personal data, passwords, authentication keys or payment details.
To improve the service, we record the country and state/province-level region at the time of your visit (an estimate based on the connecting network), which site you came from including the page path, and one display-language setting announced by your browser (for example, en-US). Location is kept to country and region only; no city or precise position is recorded. When you use the service, connection records, including your IP address, are automatically generated and retained to maintain service security and identify abnormal access. Cloudflare is the data processor for this site. Collection of this item is enabled only after this notice is published; we do not collect it retrospectively for use before collection is enabled. Query strings such as search terms are not recorded, and neither is the full list of preferred languages or the raw request headers. To identify bots, we may collect and use signals your browser reports about its type and version, along with an indication of whether automation tools are being used. These browser signals are estimates and do not conclusively identify your browser's type or version or whether automation tools are being used. Collection of this information is currently disabled and will only be enabled after this notice is published. We do not collect it retrospectively for use before collection is enabled. The raw User-Agent request header is not recorded. These records are per visit only and use no identifier that links one visit to another. Recording starts only with visits after this notice is published and is not applied retroactively to earlier visits. The region and the referring site have been recorded since 2026-09-20; the display language since 2026-09-24. Browser signals are not recorded yet.
Separately, when you visit the site, the hosting provider records your IP address, the time of the request and user-agent information about your browser and device in Cloudflare Pages’ standard access logs.
