How Veowe works out the numbers

Veowe keeps a hard line between the two, because mixing them is how money apps end up feeling untrustworthy.

Confirmed — the current balance you entered or confirmed at a check-in, each payment you recorded, the APR you typed, the goal amount you set, and the dates you chose. Veowe does not adjust these behind your back.

Estimated — the payoff date, months remaining, total interest, monthly interest, and any “what if you paid more” comparison. These are calculated from the confirmed inputs and are marked as estimates in the interface.

For each month in a projection, Veowe does the same thing:

1. Work out one month of interest by dividing the annual APR you entered by twelve and applying it to the current balance.
2. Add that interest to the balance.
3. Subtract the payment amount you told Veowe you pay.
4. Repeat with the new balance, until the balance reaches zero or it becomes clear it never will.

Savings goals run the same loop in the other direction: your contribution is added each month until the target is reached. Savings projections do not assume any interest or investment growth, because Veowe has no basis for guessing a return.

The model is deliberately simple and stated openly rather than hidden behind a friendly number:

• Your APR stays the same for the whole projection.
• Your payment stays the same every month.
• Interest is added once a month, not daily, and always before your payment is applied.
• No fees, charges, promotional periods or missed payments are modelled.
• Nothing new is borrowed on the same balance.

Real life breaks at least one of these most months. That is what the monthly check-in is for: you confirm the real balance, and the estimates re-base on the truth instead of drifting further from it.

Amounts are stored and calculated in whole pennies rather than as decimal fractions, so repeated arithmetic cannot accumulate rounding drift. Only the final figure shown to you is formatted as currency.

If a payment is smaller than the monthly interest, the balance never falls, so Veowe does not manufacture a payoff date. It says so instead. Projections are also bounded to a sensible number of years rather than running indefinitely, so a near-impossible plan does not produce an absurdly precise date far in the future.

Simplified-number and privacy display settings change only how a figure is drawn on screen. The stored amounts and the calculations behind them are untouched.

A difference between Veowe and a statement usually is not an error in either. Lenders commonly accrue interest daily, apply fees, run promotional or tiered rates, treat minimum payments as a percentage that changes as the balance falls, and cut statements on their own dates.

Veowe does none of that, on purpose: a reproducible estimate you can understand is more useful for seeing progress than an unverifiable one that merely looks precise. When the two disagree, your lender’s statement is the authority for what you owe — record it at your next check-in.

Veowe explains approaches such as snowball and avalanche without recommending one, never moves or changes a real payment, and does not provide regulated financial, debt or investment advice. If you are struggling with debt, free regulated advice is available and worth using — Veowe is a way to see the picture, not a substitute for that help.
