About
Sumslip is a free site for savings, loans, and everyday prices. The publisher is Sumslip. Write to blackningtop@gmail.com.
What you can do here
You can estimate a future balance, a loan payment, a mortgage payment, a credit-card payoff, a savings deposit, a retirement balance, a return, inflation, a percentage, a wage, a discount, a sales tax, or a shared bill. Guides next to the tools explain what the formulas include.
The same tools are written in English, Korean, and Japanese. The arithmetic is the same. Labels, examples, and warnings follow the language of the page. A Korean loan page talks about level payments and equal-principal payments because both are common. An English mortgage page asks for property tax, insurance, and HOA dues because those are how a US housing payment is usually quoted.
No charge
There is no account and no fee for the calculators. Sumslip does not sell a loan, a card, or an investment.
The publisher does not take payment to change a formula, a sample number, or a sentence.
Limits
Results are estimates. Banks round in their own order, contracts add fees, and tax law depends on where you live and on facts this site does not ask for. Use the result to understand a tradeoff, then confirm the figure that actually binds you with the statement, the offer, or a qualified professional.
Sumslip is not a bank, lender, broker, insurer, or tax adviser, and it is not a government service.
