Formula
For a fixed-rate loan, monthly payment = principal x monthly rate / (1 - (1 + monthly rate)^-months). If APR is 0, the calculator divides the financed amount evenly across the months.
Estimate a fixed monthly loan repayment, total paid over the term and the interest/fees cost.
For a fixed-rate loan, monthly payment = principal x monthly rate / (1 - (1 + monthly rate)^-months). If APR is 0, the calculator divides the financed amount evenly across the months.
Compare at least two terms. A longer term can reduce the monthly payment but increase the total interest. A shorter term can save interest but may be too tight for a real monthly budget.
This page estimates a simple fixed-rate repayment. Real offers can include arrangement fees, early repayment charges, payment holidays, variable rates and eligibility checks.
A loan payment is not only a monthly affordability number. It is a tradeoff between amount borrowed, APR, term length and total interest. A longer term can make the monthly payment look comfortable while increasing the total amount paid over the life of the loan.
Borrowing 10000 over 36 months at 8% APR produces a higher monthly payment than a 60-month term, but the shorter term usually costs less total interest. That is why the calculator should be used twice: once for the offer that feels affordable and once for the shortest term that still fits the budget.
This calculator uses a standard amortizing loan pattern. It does not include arrangement fees, early repayment charges, variable-rate changes, missed payments or insurance products bundled into a quote. If a lender quotes an APR and a separate total amount payable, use both numbers to check whether fees are already included.
Use Credit Card Repayment for revolving debt, Vehicle Finance for car offers and Can I afford this monthly payment? before adding a new fixed commitment.
Estimate monthly repayments, total repayment and total interest for a fixed-rate personal or bank loan. The useful part is not just the first answer; it is checking whether the answer still makes sense when the uncertain number changes.
Run one realistic example, then run one cautious version. For a cost page that might mean a higher price or longer time. For a date page it might mean a different deadline. For a health, study or work page it might mean a more conservative target.
If both answers point to the same next step, the result is easier to trust as a rough planning number. If they are very different, the input you changed is the one to check before you rely on the answer.
