Wedding Simple Interest Total Calculator (30 Years)

Calculate simple interest and the total amount to repay. This wedding version uses a 30-year planning term as its starting point.

The Interest figure is the extra cost of borrowing on top of the original $10,000, and the Total is the full amount to repay, so with the default figures the Interest is $15,000 and the Total is $25,000 after 30 years.

Formula

Simple interest equals principal times rate times time, divided by 100.

How it works

Interest is charged only on the original principal, not on interest already added.

Worked example

Principal $10,000, annual rate 5%, term 30 years. Simple interest is $10,000 times 5 times 30, divided by 100, which is $15,000. The total to repay is $10,000 plus $15,000, which is $25,000. That is the calculator's own result for these defaults. The principal and rate are the same on every page in this group; only the time input changes, so the interest grows by $500 for every extra year.

Who this term suits for a wedding: a comparison case against a house mortgage, where a 30-year wedding loan looks like a mortgage term but buys no house, so the couple should ask whether the debt is really a wedding cost or a home cost in disguise.

FAQs

What is simple interest?
Simple interest is interest charged only on the original amount, not on accumulated interest.

Is this wedding 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 a 30-year wedding loan the same as a house mortgage?
No, even though the term matches. A mortgage buys a house that can hold or gain value, while a wedding loan buys a day that is over at once. Over 30 years this loan costs $15,000 of interest on $10,000 borrowed, a $25,000 total for a $10,000 celebration.

What happens if the wedding is brought forward in a 30-year plan?
Bringing the wedding forward does not change the loan maths by itself, but it shortens the saving time, so the couple may need to borrow more or accept a smaller wedding. If the loan is repaid early, each year saved cuts $500 of interest.

Should a couple borrow the full $10,000 for 30 years on simple interest?
Borrowing the full amount for 30 years means paying $25,000 in total, so the couple should first check what a smaller loan, a shorter term, or saving for a few years would save. A 30-year term should be a last resort, not the default.
