Personal loans are unsecured, so rates are far higher than mortgages. The advertised "representative APR" is only offered to a portion of successful applicants — your rate may be higher.
How it works
The calculation runs in your browser as you type — there is no submit button and nothing is sent anywhere. Change any figure and the results update immediately, which makes it easy to see how sensitive the answer is to each input.
Every formula used here is standard and documented in the questions below. Where a result depends on an assumption, the assumption is stated rather than buried.
Frequently asked questions
Why is the rate so much higher than a mortgage?
A personal loan is unsecured — there is no property the lender can recover — so the rate carries that risk.
What does representative APR mean?
Lenders only need to offer the advertised rate to a proportion of accepted applicants. Your actual rate depends on your credit profile.
Is a personal loan better than credit card debt?
Usually yes if it lowers your rate and you stop using the card. Consolidating and then rebuilding the card balance is the common failure.
Is this calculator free?
Yes, with no account, no limits and no data collection. It runs entirely in your browser.
Should I rely on this for a financial or medical decision?
No. It is a planning estimate built on standard formulas and stated assumptions. For decisions that matter, speak to a qualified professional who can account for your full circumstances.
Is this calculator accurate?
The arithmetic is exact — it uses the standard formula, shown in the questions above. What limits accuracy is the assumptions: the figures you enter, and factors the formula does not model such as fees, taxes and rule changes. Treat the result as a well-founded estimate rather than a quotation.
Do I need to sign up or download anything?
No. It runs in your browser, updates as you type, and stores nothing. There is no account, no download, and no limit on how many times you use it.
