Travel Effective Annual Rate Calculator (5 Years)

Convert a nominal annual rate to an effective annual rate. This travel version uses a 5-year planning term as its starting point.

This effective annual rate is the true yearly cost after compounding, so use it to compare loans fairly instead of comparing nominal rates alone.

Formula

Effective rate equals one plus nominal rate divided by periods, to the power of periods, minus one.

How it works

More frequent compounding raises the effective rate slightly above the nominal rate.

Worked example

Nominal rate 6 percent, compounding 12 times a year, term 5 years. Using the page formula, the effective rate is one plus 6 percent divided by 12, to the power of 12, minus one, which is 6.17 percent a year. That is the calculator's stated-formula result for these defaults, and it is the same on every page in this group because the term is not an input: only the nominal rate and the number of compounding periods decide the rate. One year of interest on 10,000 dollars is 616.78 dollars at the effective rate, against 600.00 dollars at the nominal 6 percent, a difference of 16.78 dollars from monthly compounding.

As an illustration only, not the output of this page, 10,000 dollars grown at a steady 6.17 percent a year for 5 years would reach 13,488.50 dollars, a gain of 3,488.50 dollars. The page itself only gives the yearly rate; the illustration shows what that rate means over the term.

Who this term suits for a traveller: a traveller borrowing for a first campervan or motorhome, or for one big trip of a lifetime, where the loan is taken over about 5 years and the difference between the nominal and the effective rate is worth checking before signing.

FAQs

What is an effective rate?
The effective rate is the true yearly rate after allowing for compounding during the year.

Is this travel calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Is 6.17% the real yearly cost of a 5-year travel loan at 6% nominal?
Yes, on the page formula it is: monthly compounding lifts a 6% nominal rate to a 6.17% effective rate, so a 5-year travel loan really costs 6.17% a year before fees, not 6%.

Should a traveller compare nominal or effective rates when borrowing for a campervan?
Effective rates, because two loans with the same 6% nominal rate can cost different amounts if one compounds monthly and the other yearly. The effective rate puts them on the same footing.

Why does monthly compounding matter for a short travel loan?
Because interest is added every month and then itself earns interest, so even over 5 years the true yearly cost is 6.17%, not 6%. On 10,000 dollars that is 16.78 dollars extra in the first year alone.
